Profile:

LW36A-126/145 high voltage current SF6 breaker is suitable for the areas which current is 50HZ、126kV,

and the elevation is under 2500meters,used for turning on/off the electricity system, cutting down the under-load current 

and the short-circuit fault circuit, controlling 、protecting the power equipment and link circuit.

Breakers uses the SF6 gas( the Alpine region use the gas mixture of SF6 and CF4) as the isolate and arc extinguishing medium,

adopt the theory of automatic arc extinguishing,and match the spring operate instruction, 

has the advantages of powerful turn on/off ability and lower frequency, higher reliability...etc.

These products have passed the completely test of government high voltage electrical quality monitor center--

Xian high voltage electrical research institution.

The standards of high voltage SF6 circuit breaker:

IEC62271-100  high voltage current breaker
