High-voltage disconnector JW5-1100/J63

groundingoutdoor

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. 1.Products meet the following standards and technical conditions GB 1985-2004 High-voltage alternating-current disconnectors and earthing switches GB/T 191-2008 packaging-pictorial marking for handling of goods GB/T 4585-2004 Artifitial pollution tests on high-voltage insulators to be used on a.c. systems GB/T 11022-1999 Common specifications for high-voltage switchgear and controlgear standards GB/T 13540-2009 Seismic qualification for high-voltage switchgear and controlgear GB/T 20635-2006 Special environment condition Technical requirements for high-voltage apparatuses for plateau DL/T 486-2000 Specifications for HV AC disconnectors and earthing switches DL/T 593-2006 Common specifications for high-voltage switchgear and controlgear standards 2.
