    ZW7-40.5 outdoor vacuum circuit breaker

    Product Description

    ZW7-40.5 series outdoor high vacuum circuit breaker phase AC 50Hz, rated voltage of 40.5kV outdoor high-voltage electrical equipment. Spring mechanism attached to or electromagnetic actuator can remote control electrical sub, sub-gate can also be storage place manually, manually opening and closing. design performance meet GB1984-2003 AC voltage circuit breaker as the national standard, and meet IEC-56 high voltage AC circuit breakers IEC standards .ZW7-40.5 Type vacuum circuit breaker is mainly used for outdoor 35kV power transmission system control and protection also applies to urban and rural power distribution networks and industrial and mining enterprises in the normal operation and short circuit protection purposes. The product overall structure of the pillars for the vase style on insulator mounted within the vacuum interrupter, the main column under the porcelain vase porcelain vase. for frequent operation place. It have good sealing, anti-aging, high pressure, no burning, no explosion, long service life, installation and maintenance and convenient.
