Disconnector high voltage alternating-current disconnectors is three column three-phase AC
high voltage alternating-current disconnectors is three column three-phase AC 50Hz outdoor high voltage transmission equipment, to flow in case of no-load disconnect or to connect high voltage, the UHV lines, to change the power distribution device bus operation mode, as well as bus maintenance, circuit breakers and other electrical equipment, electrical isolation to achieve security. The product can be set up into a composition of the two sets to form a static-contactor isolation switch in easily, covers an area of significant savings. Can be configured with Class B induced current earthing switches in the switching provisions of GB
