75KVA Single Phase Pole Mounted Transformer

Single Phase Pole Mounted Transformer

BYT self-protected distribution transformer, which can protect itself from thunder and lighting, short circuit. Except from some similarities such as cylinder tank, hooks, lifting lugs, grounding devices, nameplates, core and winding with the conventional type.

Introduction of 75KVA Single Phase Pole Mounted Transformer

This type of transformers have characteristics and devices as follows:

1) One or two high voltage bushings are on the cover with fuse.

2) One or two arresters are installed on the wall of the tank, whose top end is near to the high voltage bushing, and connected to the bushing by a copper strip. One secondary breaker switch is above the winding inside the tank, and here are operating handle,overload reset and signal light.

3) Low voltage bushing is educed from the wall of the tank, grounding device is fixed to position X2. One end of the single bushing leads out through the high voltage bushing, the other end is ground connection.

4) All units are built in accordance with IEC60076, ANSI/IEEEC57.12.20, CSA C2.1-06,CSA C2.2-06 and etc.
