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.
