LW10B-550 SF6 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.

LW10B-550/CYT SF6 circuit breaker, with the advantages of strong current-carrying capacity, excellent breaking performance, high reliability and so on, is equipped with CYT hydraulic mechanism, which adopts modular design, built-in hydraulic pipes, so as to realize no external pipe, no leakage.

 

Main Features

1        High insulation level, excellent breaking performance of the interrupter.

2        Equipped with independently-developed CYT hydraulic mechanism, all    hydraulic pipes built in, no leakage, good mechanical reliability.

3        Adopting imported control valve, with stable performance and anti-slow-opening function in case of pressure loss.

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