Between the circuit breaker and the three-position isolation mechanism is the five-prevention interlock,
a simple and reliable structure. It prevents operators from mis-operation.
The integrated transformer is installed at the cable bushing, more than 700 mm high.
If high-voltage incoming wires are live or the operating handle is pulled out, it can immediately realize automatic locking.
Over-temperature protection function is built in the device, so it keeps the device safe and reliable. In case of emergency, it can realize mechanical unlocking.
It’s of easy operation, good insulation performance and convenient maintenance. It’s used for uneven installation base.
