12kV Indoor 3 Phases Switchgear Isolating Switch

3 Phases Switchgear Isolating Switch 11250A, 50Hz, 2.Usage:Power 3.L/C ,T/T 4.Compact, small volume, safety and reliable

12kV Indoor 3 Phases Switchgear Isolating Switch

1.  Features of Main Structure

1.1 Functions of isolating switch and earthing switch are realized by one driving shaff and one movable contact knife in the condition of air insulation. The product is a new multi-function switch that owns three operation positions of on, isolating (off) and earthing.

1.2 The structure of products is reasonable, copact, smsall volume, safety and reliable. The performance of anti-wrong-operation is quite good. It is an ideal matched product of minimized switchgear.

1.3 When on and off operation, turn a crank connecting to a shaft by an operating handle, a connection rod make a movable contact knife rotate for closing, isolating(testing) and earthing.
