Transportable Unitised Transwitch Unit:

It is a 11/6.6/3.3 KV system which consists of :
a) HT Breaker b) Transformer c) LT Panel d) HT Starters
It is used in open cast mines to feed power to over burden drill and excavator wherein the motor is operable at 3.3KV/415 Volts. The design and operational features is such that it is made of modular units viz. HV Cubicle, Transformer & LT Panel.
The system is skid mounted and the total system can be transported by pulling from one location to another. It recieves power of 11/6.6/3.3 KV & gives output of 3.3KV/415 Volts. Hence, it has multi purpose use. The incoming is through cable entry box and outgoing is through LT/HT plug socket.
