Outdoor high voltage vacuum circuit breaker Focus on the details of quality to win
概述 Overview
ZW32-12 型户外真空断路器 ( 以下简称断路器 ) 为额定电压 12kV,三相交流 50Hz 的户外配电设备。主要用于开断、关合电力系统中的负荷电流、过载电流
及短路电流。适用于变电站及工矿企业配电系统中作保护和控制之用,及农村电网频繁操作的场所。
本断路器具有体积小、重量轻、防凝露、免维护等特点,能适应较恶劣的气候条件和污秽环境。
最新小型柜
ZW32-12 outdoor vacuum circuit breaker (hereinafter referred to as circuit breaker) for the rated voltage 12kV, three-phase AC 50Hz outdoor power distribution
equipment. Mainly used for breaking, close the power system load current, overload current and short circuit current. Suitable for substation and industrial and
mining enterprises in the distribution system for the protection and control purposes, and rural power grid frequent operation of the place.
The circuit breaker has a small size, light weight, anti-condensation, maintenance-free features, can adapt to the more harsh weather conditions and dirty
environment.
