10 DESIGN DATA 10.1 Design Basis

The design basis for this specification mirrors that in ENA TS 43-40, utilising an empirical approach. 10.2 Conductors

The tension of any line conductor at a temperature of -5.6º Celsius and subjected to a design wind and ice loading appropriate to the environment in which the line will be situated, shall ensure that the conductor will have a minimum factor of safety of 2.5 over the rated breaking strength of the conductor. The basic span length is specific to the conductor and environment in which the line will be situated and will be specified in the relevant appendix. 10.3 Crossarms

The minimum factor of safety on all Crossarm assemblies and associated steelwork is 2.5 in a Non Severe Weather Environment and up to 3.5 in a Severe Weather Environment on the yield stress of the steel.

10.4

Supports

The strength of supports is derived from formulae contained in BS 1990 part 1. The stresses created in intermediate supports are bending stresses due to windage on conductors, the loading point being 230mm above pole tops. All "in-line" intermediate and section poles have a minimum factor of safety of 3.5 in all Weather Environments. The stresses created in stayed supports are crippling stresses due to stay tension, steelwork and vertical conductor loads acting at the pole top. All angle and terminal poles have a minimum factor of safety of 2.5 in a Non Severe Weather Environment and up to 3.5 in a Severe Weather Environment. Pole top horizontal loading has also to be maintained within specified limits to prevent pole top splitting. Poles shall be of a sufficient diameter to withstand the above-mentioned stresses. Therefore the minimum pole grade allowable in Appendix 1 only shall be "Medium", all other Appendices require a minimum pole grade of "Stout" to BS 1990 Part 1 for the purpose of this Specification. In addition a minimum pole top diameter is specified in Table 11 of appendix 1 or Table 10 in all other appendices, this pole top diameter may exceed the minimum pole top diameter quoted in BS 1990 Part 1. This more onerous requirement should be taken into account when selecting poles. For Pinus Sylvestris, the average ultimate extreme fibre stress value used is in all pole calculations is 53.3N/mm².the average modulus of elasticity fibre stress is 10054N/mm². In all cases, the appropriate pole strength has been calculated using a maximum taper of 11.25mm/m. 10.5 Stays

The minimum factor of safety on stay assemblies is 2.5 in a Non Severe Weather Environment and up to 3.5 in a Severe Weather Environment based on the minimum failing load of the assembly. 11 MATERIALS Except where otherwise specified all materials used in the construction of lines to this Specification shall comply with current British Standards and ENA Technical Specifications as appropriate. Only Energy Networks Approved materials shall be used.

12 TECHNICAL REQUIREMENTS FOR THE ERECTION OF LINES 12.1 Structure Type and Capabilities

Table 1 of appendices 1 to 6 contained within this specification provides details of the various structure types, limiting span length and angle of deviation detailed under gradient conditions as applicable, together with the appropriate Energy Networks drawing reference numbers. The maximum span lengths indicated take account of conductor clashing and steelwork strength limitations. Poles, which are subject to Uplift at ­5.6ºC, shall be sectioned. 12.2 Wood Poles

Wooden poles shall be of the species Scots Pine (Pinus Sylvestris) and shall be imported from a Nordic Country and grown at latitude greater than 60°00'00"N. Poles shall be creosoted to BS144 using the Rueping empty cell process. In all circumstances poles shall comply with BS 1990 Part 1 and ENATS 43-88 Parts 1 and 2. They shall be supplied drilled and scarfed. Pole blocks shall be fabricated to ENATS 43-91 drawing 439103 Type 2 and drawing 439112 Type 1 & 2 as required. 12.2.1 Section, Section Angle and Terminal Supports

The gradient limitations quoted in Table 1 of appendices 1 to 6 are derived from the conductor vertical load, which can be accommodated by the Crossarms and is expressed as a Downpull gradient, which is measured between adjacent pole tops. The gradient limitations quoted in Table 1 refer to Downpull gradients on each side of the support and therefore it is acceptable to summate gradients. The gradients limitations quoted in Table 1 are therefore permitted on both sides of the supports. Terminal supports are designed to allow for the appropriate value on one side of the structure only. The Uplift limits on section, section angle and terminal structures shall be taken as being the same as for Downpull detailed in Table 1 of the relevant appendices.

12.2.2

Supports

For Section and intermediate structures the maximum Downpull shall be no greater than an equivalent gradient of 1:10 to the horizontal plane on either side of the structure.

1910

1:10*

1:10*

For hillside applications, the maximum gradient quoted in Table 1 of appendices 1 to 6 for intermediate supports is limited by the method of conductor attachment and is permitted only where angle 1660 and where angle 1910 where these limitations cannot be satisfied a section structure should be employed. 1910 1660

1:4

For Terminal structures the maximum Downpull shall be equivalent to a gradient of 1:5 to the horizontal plane on one side of the structure only. Any structure not complying with the requirements set out above shall be subject to approval. Approval will normally be sought when the line is being planned.

12.3

Pole Strut Loadings

The strut loading imposed on poles due to vertical components of stay and conductor tensions including any auxiliary equipment at specified angles of line deviation and ground slope conditions are specified in the Tables 7, 8 & 9 of appendices 1 to 6. For all single pole 11kV structures an allowance of 600kg has been included for the attachment of auxiliary equipment. During construction, section poles may be utilised as temporary terminals. Where a single pole section structure is required for this situation, the pole must be graded such that it is capable of a terminal load condition as detailed in pole strut loading tables of the relevant appendices. Temporary terminal stays will be fitted in accordance with Energy Networks Approved staying methods and placed at the ends of the crossarm and the stay anchors positioned no closer to the pole than two pole lengths, this may require to be increased significantly where conductors in excess of 100mm2 are employed to limit the loading applied to the pole and crossarm assembly. 12.4 Windspan and Foundation Requirements

Pole foundations shall be designed to withstand the overturning moment due to windage on conductors, poles and insulators. Foundation design shall also take account of the rupturing capacity of the ground. In excavating foundation holes, the minimum amount of soil shall be disturbed in order to take advantage of the load bearing value of the virgin ground as far as possible. Back-filled soil shall be compacted using hand or mechanical compaction methods, not more than 150mm of loose soil shall be returned between each ramming operation. All structures shall have a minimum of one foundation block fitted at a minimum of 500mm below ground level. Where an angle of deviation exists the top foundation block shall be on the inside of the angle. Where the quality of backfill material is unsuitable it will be necessary to replace the excavated material with a suitable imported backfill, however an Energy Networks approved soil additive, e.g. Permasoil, may be used to improve the quality of poor soil.

Span Lengths

The basic span length adopted by this specification is dependant on the chosen conductor and the environment in which the line will be situated and as such is specified in the appropriate conductor appendices. Individual spans will normally be within ± 20% of the chosen basic span. The average span length of every kilometre of line (not necessarily between section supports) shall not be greater than the basic span. In extreme circumstances an occasional Maximum span shall be permitted. In such cases the maximum span length for individual structures is given in Table 1 of appendices 1 to 6. No more than two adjacent maximum spans shall be permitted as detailed in Table 1 of appendices 1 to 6 Where Long Span "H" Pole Structures are employed, in line stays shall be installed against the long spans to reduce the effect of out of balance tensions on the adjacent spans. 12.11 Section Lengths

Conductor Design/Erection Sags and Tensions

Ordinates for plotting uplift curves are based on conductor design tensions. Ordinates for plotting ground clearance curves assume the use of new conductor and include an allowance for long-term creep over a period of 25 years. Conductor design sags / tensions are given in Table 2 of appendices 1 to 6. Erection sags and tensions are given in Table 4 of appendices 1 to 6 and are based on the conductor design tensions, but have been subject to a 10% over tension to accommodate the long-term stretch of the conductor during the life of the line. The conductors shall be pre-tensioned for a minimum time of 60 minutes. At 15-minute intervals during this period, the tension or sag shall be adjusted in order to maintain the correct value. Conductor Pre-Tension sags / tensions are given in Table 3 of appendices 1 to 6. The erection sags given in Table 4 of appendices 1 to 6 have been calculated from the conductor design tensions.

Appendix 7 Installation requirements for Conductors incorporating Optical Fibres 13 INTRODUCTION This Appendix has been prepared to provide a design for 33kV overhead lines suitable for installation on the companies' network, utilising optical fibre communication cores embedded within the phase conductors. The optical fibres are enclosed within two separate stainless steel tubes in a phase conductor. This appendix is complementary to the equivalent standard conductor installation requirements, and should be read in conjunction with it. This appendix details the specific stringing requirements for: 200mm² AAAC POPLAR Equivalent OPPC (L34) 300mm² AAAC UPAS Equivalent OPPC (L36). 13.1 General

When compared to a standard overhead line construction, lines incorporating optical fibres shall have the centre phase conductors substituted with an equivalent optical phase conductor (OPPC). All overhead line components and design parameters shall comply with the requirements of the standard conductor as specified in the relevant appendix with the exception of those specified in the following clauses. There are specific installation techniques, which require to be employed when installing lines incorporating optical fibres within the conductors; these are documented in Energy Networks document OHL-18-022. 13.1.1 Optical Phase Conductors

The maximum working tension of an equivalent OPPC is designed to be the same as for a standard AAAC conductor. However, due to the difference in physical construction of the OPPC when compared with standard conductor, the maximum sag of the OPPC will be marginally less than standard conductor, therefore the maximum design sag for the standard conductor should be used when profiling as indicated in Table 2 of the relevant appendix. 13.1.2 Crossarms, Supports and Stays

As the loadings for the equivalent OPPC are almost identical to the standard conductor, structure sizing, stay strength and their deployment, and Crossarm sizing shall all be as detailed in the relevant standard conductor appendix.

13.2

Materials

Except where otherwise specified, all materials used in the construction of lines to this Appendix shall comply with current British Standards, ENA Technical Specifications and international standards where appropriate. Only Energy Networks Approved materials shall be used. 13.2.1 Optical Phase Conductors (OPPC)

The optical conductors physical and electrical parameters considered by this specification are detailed in Energy Networks document OHL-03-96, each conductor shall incorporate two stainless steel buffer tubes each containing a minimum of 12 single mode optical fibres. 13.2.2 Vibration Damper

As for standard 33kV line construction, no vibration dampers are normally required to be employed on the OPPC. 13.2.3 Suspension Components

33kV polymeric post insulators and armour grip suspension clamps shall be used at all intermediate insulator positions; the proposed suspension arrangements are not designed to take any uplift load. Where the structure is deemed to be in uplift, the line should be sectioned and tension support components employed in accordance with Section 11.1.

13.3

Optical Splice Enclosures

At OPPC in-line splice and terminal positions, only Energy Networks Approved fibre optic splice enclosures may be installed. These fitting comprise of a rigid stand off composite insulator and one or two fibre optic splice chambers where appropriate. At Terminal positions these will be mounted on two H Pole Carry Over Channels as detailed in Energy Networks Drawing Reference SP4008885 and secured using two transformer-clamping plates as detailed in ENATS drawing reference 439529. At in-line splice positions, on "H" Pole section structures the unit will be mounted on the centre phase conductor section strap, on Single pole section structures the unit will be mounted on the outside of the angle on the section crossarm this component shall be substituted for items 11 & 13 of the general assembly drawings They will be located on section and terminal structures as indicated on Energy Networks drawing reference SP4019865. In order to prevent damage to the stainless steel buffer tubes containing the Optical Fibres the line conductor should be dressed directly from the dead end fitting directly to the splice enclosures and should be installed in such a manner to ensure the minimum-bending radius of the conductor is not compromised. Only Energy Networks Approved persons shall carryout the splicing of the optical fibres. 13.3.1 Electrical Connections

At terminal positions where a load carrying electrical connection is required for example to a cable termination these should be connected to the Splice enclosure jumper by one or two 3bolt parallel groove clamps. (See also general arrangement drawings and associated component listings). Parallel Groove clamps should be used for all electrical connection associated with the OPPC. It is essential that all conductors are thoroughly cleaned using a suitable wire brush and a Energy Networks approved conductive paste should be applied to the conductor prior to the application of the parallel groove clamps; the clamps should be tightened with a suitable torque wrench to the manufacturers recommended torque. Compression fittings must not be applied to the OPPC conductor. At Splice Enclosures, the termination connecting rod should be cleaned using 150-grade abrasive paper and an Energy Networks approved conductive paste should be applied to the conductor and connecting rod prior to the application of the parallel groove clamp(s).

Earthing

As is normal practise all metalwork including Optical Splice Enclosures on all structures shall be bonded and or earthed in accordance with Energy Networks document OHL-25-01. A connection hole is provided on the base plate of the Optical Termination Unit to which the earth-bonding lug should be connected. 13.5 Optical Fibre Cable Connections

The Fibre Optic underground cables shall secured every 500mm down the pole and protected at the bottom of the pole by cable guards 3.0m long sunk 150mm into the ground .

Appendix 8 Installation Requirements for Horse OPGW This Appendix has been prepared to provide a design for a OPGW conductor to replace the existing "Hardex" communication network on existing 33kV overhead lines structures This appendix details the specific stringing requirements for a 70mm² ACSR Horse Equivalent OPGW 14 General Where there is a requirement to modernise the existing "Hardex" communication network an Optical Ground wire may be employed in accordance with the following requirements. There are specific installation techniques, which require to be employed when installing conductors incorporating optical fibres; these are documented in Energy Networks document OHL-18-022. 14.1.1 Optical Ground Wire

The maximum working tension of an equivalent OPGW is designed to be the same as for a standard AACSR conductor. However, due to the difference in physical construction of the OPGW when compared with standard conductor, the maximum sag of the OPGW will be marginally less than standard conductor, therefore the maximum design sag for the OPGW conductor may be used when profiling as indicated in Table 2 of this Appendix. See Section 12.13.1 for guidance on minimum height of conductors. Note:- Land usage may have changed since the original line was profiled and obstacles may have been erected which could infringe on the basic requirements set out in section 11.13.1 therefore it is recommended this is given full consideration. 14.1.2 Supports and Stays

As the loadings for the OPGW are not significantly greater than the "Hardex" Communication cable there are no requirements to alter existing structures.

14.2

Materials

Except where otherwise specified, all materials used in the construction of lines to this Appendix shall comply with current British Standards, ENA Technical Specifications and international standards where appropriate. Only Energy Networks Approved materials shall be used. 14.2.1 Optical Ground Wire (OPGW)

The optical Ground Wire considered by this Appendix is detailed in Energy Networks document OHL-03-96; each conductor shall incorporate two stainless steel buffer tubes each containing a minimum of 12 single mode optical fibres. 14.2.2 Vibration Damper

No vibration dampers are normally required to be employed on the OPGW . 14.2.3 Suspension Components

The OPGW shall be supported at all intermediate positions using a standard pole outrigger bracket (ENATS Drawing Reference 431403) in conjunction with a galvanised steel suspension link connected to an Armour Grip Suspension Clamp. The pole bolt securing the outrigger bracket should be positioned 225mm above the profiled OPGW position to allow for the suspension components. The proposed suspension arrangements are not designed to take any uplift load. Where the structure is deemed to be in uplift, the line should be sectioned and tension support components employed in accordance with Section 12.1.

14.2.5

Connection to Splice Enclosures

At OPGW intermediate and terminal splice positions an optical fibre splice enclosure is required to facilitate the splicing of the optical fibres. The optical splice enclosure shall be fixed above anti climber level and secured using two 10mm x 75mm galvanised coach bolts. At terminal positions the Fibre Optic underground cables shall be secured every 500mm down the pole and protected at the bottom of the pole by cable guards 3.0m long sunk 150mm into the ground. 14.3 Conductor Design/Erection Sags and Tensions

Conductor design Sags and tension are given in Tables 2 & 3 of this appendix. The original lines incorporating "Hardex" Communications cables were profiled using a "Wolf" Sag template (normally 500C) The design sag of the Horse OPGW replacement at an Assumed maximum ambient temperature of 450C whilst greater than the "Hardex" is equal to or slightly less than the Wolf Profile used when the line was originally planned and hence the Horse OPGW may be strung as a direct replacement for the "Hardex" communications' cable. The erection tensions given in Tables 3 of this appendix are based on the conductor design tension, but have been subjected to an over tension equivalent to a -130C temperature shift to allow for bedding in of the strands and long term creep of the conductor during the life of the line. No pre-tensioning or other adjustments is necessary during the erection of the line

Location of OPGW Attachment Points on Structures.

The Attachment positions for OPGW on all structures will be as follows:14.4.1 Straight Section, Intermediate and Pin Angle Structures

The Outrigger Bracket (ENATS Drawing Reference 431403) shall be installed 1365mm below phase conductors for spans up to 107m. 1675mm below phase conductors for spans up to 152m. 14.4.2 Angle Section and Terminal Structures

The Eye Bolt (ENATS Drawing Reference 439603) shall be installed 1520mm below phase conductors for spans up to 107m. 1830mm below phase conductors for spans up to 152m 14.5 Bonding and Earthing of OPGW and Components

As is common with all metalwork on structures constructed to this specification At Optical Splice enclosure positions the splice enclosure will be required to be bonded in accordance with section 12.16. The OPGW shall also be bonded to all steelwork on the structure in addition it shall be earthed at intervals of approximately 400m in accordance with section 11.16.
