Product Detail

Model No.: PYXZ

Production Capacity: 500sets/month

Delivery Date: 1month

Means of Transport: Ocean

Packing: wooden packing

rated voltage: 10KV

PYXZ type prefabricated switching station apply to AC 50 HZ,12KV industrial and civil cable power supply system,especially suitable for cable ring net

All of the charged component in the switching station sealed in metal box that filled with SF6 gas, switching station fulled of SF6 as interrupter and insulating medium,using manual or electric energy storage spring mechanism.Each device has a barometer that it can check the internal pressure, each device also provides safety valve to pressure relief to ensure the safety of operation in the condition of internal overpressure. the grounding switch of actuator, fuses and outlet ends is still in the air, convenient for maintaining and replacing fuses.
