Product Description

 

126 kv dead tank for general substation use electric circuit breaker

 

Quick Detail: 

Type LW24 outdoor H.V A.C dead tank SF6 with voltage range from 125 to 220kv is a new kind of circuit breaker

with self-blast interrupter and spring operating mechanism.

 

The lastest achieve-arc gas-blast pressure adapter for breaking current extinguishing principle is employed, most of the

energy for the breaking of short-circuit current is required by the arc itself. Therefore, the demand for operating

power is reduced significanlty. The three phase interrupters are placed inside three metal enclosures respectively.

 

The circuit breaker can be machanically three phase gang-operated, from both a remote electrical control and a

local manual control. Type CT20-II spring operating mechanism, provided with the product, is a mechanism with

low operating power, minimun maintenance work need and high realiabiity.
