LW10B-252/363 SF 6 Circuit Breaker

Description

Brief Description

Circuit breaker is used for making and breaking normal current, fault current and switching lines to realize the control and protection of power system.

Each pole of LW10B-252 circuit breaker has one break without parallel capacitor and each pole of LW10B-363 circuit breaker has double breaks with parallel capacitors. For both of products, each pole is equipped with a hydraulic operation mechanism, which can make single-pole operation and/or three-pole-gang operation.

Complete and rigorous type tests have been performed on the series products, the type test certificates were issued by Italy CESI Certification Center in 1998.

 

Main Features

1        Excellent breaking capacity with advanced construction.

2        Valve system of hydraulic mechanism can effectively prevent oil leak, and each pole is equipped with density relay to monitor SF6 leakage.

3        Good insulation performance.

4        The components and spare parts are highly interchangeable with other products of PINGGAO, experienced manufacturing technology, easy to maintain on site.
