Power and Distribution Transformers

Listing ID #4325572

Three phase transformers are designed to effectively reduce line cost and line loss and improve the quality and reliability of the electrical energy supply system they are overhead type distribution transformers, suitable for direct pole mounting, completely self protected against lightning or switching, surges and secondary overloads. Three phase transformers are capable of withstanding mechanical and thermal stress caused by short circuiting in accordance with IS 2026. It can be supplied either in corrugated panel or pressed steel radiators.

Power transformers ranging from 10KVA to 5MVA with voltage class of 33 KV. Power transformers convert-level voltages from one level or phase configuration to another. They can include features for electrical isolation, power distribution, and control and instrumentation applications. Transformers typically rely on the principle of magnetic induction between coils to convert and / current levels.

Power transformers can be configured as either a single-phase primary configuration or a three-phase configuration. Transformers are available with either copper or aluminum windings. These transformers can be free breathing while hermetically sealed are without breathing with bolted cover.

The liquid filled transformers can be supplied with cooling either by corrugations on the side of the tank or Pressed Steel Radiators mounted on Tank body. Transformers can be filled with either oil one of several low flammability synthetic fluids Both type can be supplied with HV and LV Switchgear incorporated into substations.
