Single Phase Transformer

We are manufacturing single phase transformer 50 Hz oil cooled pole mounted and platform mounted double woundcopper and aluminium wound step up and step downcore type transformer ranging from 5 KVA to 100 KVA up to 33 KV Class. Normally in a single phase transformer round tanks are used. These single phase transformer are capable to withstand vacuum and oil leakage tests. The core so formed has rectangular cross section and accordingly the LV and the HV coils also have rectangular geometry. Whereas enameled copper conductor is used for the HV winding paper cover or enameled rectangular strips are used for the low voltage windings. The insulation is designed to withstand the specified impulse level. The coils are progressively wound the HV being wound directly on the LV coil. This ensures that the coils are rigid compact and have high mechanical and dielectric strength. Such winding ensures better short circuit withstand capability for the transformer. The result is a single coil structure having high strength which prevents movement of conductor of the coil in the event of any short circuits on the transformer during its operation.
