Product Overviews

ZW7-40.5 series outdoor high-voltage vacuum circuit breaker is used in a three-phase A.C. 50Hz, voltage of 40.5kV electric system, suitable for breaking and making load current, overload current and short-circuit current.

It is applicable to power station, transformer substation, power equipment and power line for protection and control. Each set of the circuit breaker installs a LZZBJ4 current transformer which has four winding. It can be used for calculating, measuring and protecting. The circuit breaker has chara cteristics of anti-knock, strong pollution-proof ability, small volume, simple structure, easy to use, good breaking performance and high reliability, etc.
