ELDEE holds BIS license for supply of distribution transformers up to 200 kVA, 11 kV class & 2500 kVA, 33 kV class as per IS 1180 - Part 1 (2014). ELDEE offers distribution transformers in energy level 1, 2 or 3 as per customer's requirements. ELDEE offers distribution transformer as per SAN 780 / IEC 60076 for overseas clients.
Prime grade of core materials - CRGO steel sheet material as per IS:3024 of BIS approved quality / amorphous core material is used resulting in low value of losses, magnetizing current & long life of transformer.
Electrical grade of copper or aluminum for distribution transformers up to 2500 kVA rating can be used for transformer winding resulting lesser load losses & longer life of distribution transformers.
Paper covered conductor / enameled conductors are used for HV winding.
Foil winding, latest technology is also used for high current distribution transformers (LV), resulting in compact design & excellent performance against short circuit stresses.
Sealed / non sealed type of transformer is offered as per customer's requirement.
Distribution transformers can be equipped with ERW tubes, corrugated tank or pressed steel radiators.
Transformer tanks including radiators are given shot blasting treatment followed by Zinc spray treatment by cold spray / flame gun process to give a long lasting anti rust corrosion paint finish.
Transformers with special oil / easter grade are also offered for non fire propagated areas.
Complete range of transformers are designed with solutions towards increased efficiency materials, space saving & reduced noise.
ELDEE has NABL accredited test facility for all routine & type tests & special tests. Impulse and short circuit tests are carried out at independent test houses.
Distribution transformers can be designed pole mounted as well as for ground / pad mounted.
Specially designed station /auxiliary transformers in ratio 33/0.433 kV for substation auxiliary supply could also be supplied.
