PRODUCTION PROGRAM Low voltage transformers LV/LV Dry type rating up to 630 KVA nominal voltage up to 1,1KV Oil immersed rating up to 630 KVA nominal voltage up to 1,1KV Distribution transformers MV/LV Dry type rating up to 2500 KVA and nominal voltage up to 24KV Dry type cast resin rating up to 2500 KVA and nominal voltage up to 36KV Oil immersed rating up to 2500 KVA and nominal voltage up to 72KV Power transformers HV/LV HV/MV Dry type cast resin rating up to 10 MVA and nominal voltage up to 36Kv Oil immersed rating up to 25 MVA and nominal voltage up to 72 Kv Power transformers can be equipped with on load tap changer. The production range includes, besides the standard types, autotransformers and transformers to be used for starting , insulation , earthing , induction furnace, rectifiers . MANUFACTURING STANDARD The transformers produced by Elettromeccanica Colombo are manufactured in compliance with the following standards and relevant updating documents: oil immersed transformers CEI 14-4 IEC 76 IEEE ANSI C 57,12.00 dry type and cast resin transformers CEI 14-8 IEC 726 IEEE ANSI C 57,12.01 Upon request it is possible to produce transformers in compliance with any other Standard, like BSS, VDE, AFNOR ... QUALITY ASSURANCE SYSTEM All transformers are submitted to accurate controls during the production and to final test in our test room , where we carry out the routine test and type tests. Special test -on request-are made normally at CESI Institute in Milano or in others University Electrical Departments. Our firm has made several complete tests at CESI Institute with positive results ; that proves the reliability of our transformers. Particular care is given to quality problems starting from the design-planning moment .The components used are accurately checked in the purchasing , stocking , construction and assembling phases . The company is applying a Quality Assurance System according to ISO 9001 Standard, certified from NQA LTD - England - NR 14794
