Product Description
This series of high voltage disconnectors is a new type of switching device, modernized and designed by our factory in accordance with current national and international standards to eliminate some of the problems inherent in the previous GW5 disconnectors. The disconnector itself is equipped with grounding blades, which can effectively prevent erroneous operations such as “applying grounding to a live line and turning on when grounding is applied,” while operating personnel do not need to additionally install portable grounding. The disconnector can be flexibly equipped with one-sided or two-sided grounding, manual or motor drive, and integrated installation of surge suppressors. The disconnector is equipped with a built-in mechanical interlock to prevent erroneous operations, and can also be additionally equipped with an electromagnetic lock to implement mutual interlocking between the main and grounding blades, as well as between the disconnector and the circuit breaker. Widely used as component equipment for photovoltaic and wind power plants, substations, static reactive power generators SVG. This product has superior electrical and mechanical performance and is an upgrade to existing 10-35kV class outdoor disconnect switches. This series motor drive GW5 can be combined with GW4, which can realize a perfect dual switching device and achieve higher economic efficiency as the main switching unit of a power plant.
