Power & Distribution Transformers 8 KVA to 5000 KVA in 11 & 33 KV voltage class.
K.S. Power transformers are designed and tested as per IS: 2026, BS-171, IEC-76 & IEC-726.
Transformer will be connected as per vector group reference Dyn 11.Other vector groups can be offered as per specific requirements.
Cables are designed for a maximum temperature rise of 50/55 degree C of oil/winding. Lower temperature rise can be offered on request.
The core is considered from low loss, cold rolled, grain oriented, annealed laminations of electrical sheer steel conforming to the international standards. Special frame is built in-house for clamping the core to reduce the magnetic noise as well as making the whole structure rigid and robust.
Coils are wound with electrolysis high conductivity paper covered or synthetic enameled copper conductors. Coiling ducts are provided to keep the hot spot temperature as low as possible. Coils are dried in electric ovens. Rigid connection support and coil clamping is provided to ensure high short circuit strength.
Recompressed board, Parmali board and Japanese insulation paper of best quality in used.
Off Circuit Tap Changing Switch Tapings from +5% to -5% in steps 2.5% for HV variation or as per customer's requirements.
Tapping range as per specific requirements can be offered. OLTC for remote , auto, parallel operation can also be offered.
