JW5-1100/J63 type Disconnector

Description

JW5-1100/J63 type Disconnector

JW5-1100/J63 high voltage earthing switch adopts folding plug-in structure, can effectively reduce the area and reduce the cost of power station construction, uses the counter weight and balance spring together to balance the change of potential energy, flexible and convenient operation, stable and reliable opening and closing process. When the closing is finished, the support rod and grounding arbor constitute a triangular frame structure, after the closing, the product has a higher stiffness and stability. Rated short-time withstand current 63kA(3s), mechanical life 5000 times, the technical performance is stale and reliable. This product has been passed the national identification in July 2010 which was organized by China Machinery Industry Federation, its technical performance reached the international advanced level.
