BURNDY® HYGROUNDTM vs. Exothermic Welding

Less equipment. No more than four to seven tools and accessories are required to make an average grid installation. Range-taking. Accommodate a broad range of conductor sizes and configurations that significantly reduce the number of installation components required. Compatible. Since some competitors' connectors, tools, and die designs are based on the HYGROUND system, compatibilities do exist in certain areas. Minimal space limitations. The rotatable-head feature on some BURNDY compression tool models further reduces any possible space constraints. Longer shelf life. Simple storage precautions maintain functional performance for prolonged periods. Severe space restrictions. Making exothermic connections in confined spaces is severely limited because of mold size and clamp restrictions. Shelf life/storage issues. Shelf life of exothermic powder and molds is potentially very short. Dampness and moisture can adversely affect the performance of the powder and molds by hindering the ignition sequence. Handle with care. Graphite molds are fragile and require care in handling. More equipment. Multiple tools and accessories are required to make an average grid installation. Non-range-taking. Each application requires a different mold and appropriate accessories for each conductor combination and configuration.

BURNDY HYGROUND connectors meet and exceed all industry specifications for system standards and performance.

REA Utilities The Rural Electrification Association (REA) represents more than 1,000 rural electric systems that own and maintain nearly half of the nation's poles and powerlines, and many are protected by BURNDY HYGROUND. BURNDY has obtained REA listing for its YGL HYGRIDTM cross-grid connector to meet the requirements of this market.

Tool life. BURNDY's quick-charge batteries provide peace of mind in remote areas, and its tools have been life-cycle tested to over 100,000 cycles without failure. Safety. Making a compression connection using the BURNDY HYGROUND system is an inherently safe process. There are no potentially hazardous by-products, and permits use in any location. Weather or not. HYGROUND connections may be made even in wet and other inclement conditions. Inspection. HYGROUND compression connections can be easily inspected dimensionally and visually with conclusive results. Installation. Connections can be made even in the most severe site and/or weather conditions to keep jobs on schedule and man-hours to a minimum. Costs. User-friendly, all-weather installation cuts labor costs significantly.

Mold life. The weld reaction process and normal handling cause the mold openings and mating surfaces to wear and break, rendering the mold inoperative, normal life expectancy is 50 to 75 connections per mold. Safety. Making an exothermic connection requires adherence to strict installation procedures, including fire safety. This may restrict the use of where equipment can be used. Weather restrictions. Exothermic connections can be made under dry conditions only.

Federal Government · FAA 019B-85 Airport Grounding · Occupational Safety Hazard Association

Army Corps of Engineers While the Army Corps of Engineers has not adopted one central standard for below-grade grounding, BURNDY HYGROUND has been included in several major projects of the Armed Forces and is also approved for use by other federal agencies including the FAA and OSHA.

International Firms Many international firms are having difficulty in obtaining export and import licenses for exothermic material. Current world conditions are forcing some governments to consider exothermic powder an explosive. Care and shipment of this material are other problems, as is proper training for overseas installers. None of these inherent problems exist with BURNDY HYGROUND materials.

Distributors Unlike exothermic materials, distributors can stock BURNDY HYGROUND connectors without fear of any safety issues or fear of any inventoried product becoming damp and inoperable. By stocking relatively few HYGROUND items, a distributor can easily service the majority of enduser requirements. And BURNDY's customer service and sales departments are well regarded within the industry.

Petrochemical Plants At petrochemical plants, safety is a primary concern. Proper grounding is a large part of safety as managers look to protect their people, plants, and equipment. Your facility can realize huge cost savings -- and great peace of mind -- by using the BURNDY HYGROUND compression system that can be safely installed in areas containing hazardous chemicals or gases.

The inspectability of completed grounding connections is of great concern within the electrical community. A growing number of industries are demanding a higher degree of traceability to confirm the quality of an installation. This is another solid example of why the BURNDY HYGROUND compression grounding system is the clear choice. When a BURNDY HYGROUND tool and die combination makes a compression connection, it also embosses an identification code into the installed connector. This mark allows you and the electrical inspector to visually -- and quickly -- confirm that the proper connector, tool, and installation die were used and that the connector has been correctly placed. And since BURNDY HYGROUND compression tools are designed to complete the crimp before releasing, you can be further assured of the installation quality. The permanent embossment of BURNDY HYGROUND's range-taking connectors allows for proper inspection days or even weeks after the installation was completed. This method of inspection is far more reliable and less subjective than checking an exothermic connection with the tap of a hammer.

Range-taking tool and die design minimize inventory and provide for multiple connector combinations that are consistent and reliable.

Most compression elements are prefilled with our exclusive PENETROXTM compound to inhibit moisture and contaminants.

Inspection ports are provided in terminal and splice connectors to ensure proper insertion of the conductor for increased quality assurance.
