HV Isolation Switch

الوصف

a, the main knife rotating conductive contact with advanced friction-type contact structure;
　　b, sub-closing self-locking two states have maintained, effectively prevent the wind, electric power and other factors which led the movement away from contact;
　　c, rotate the use of oil-bearing areas and copper alloy sleeve shaft, with self-lubricating ability, to overcome the rotating part of the rust and catching;
　　d, using advanced surface treatment technology and use a rust-proof aluminum, stainless steel and other materials, greatly increased the surface corrosion resistance;
　　e, three-pole main switch for the linkage, there are electric and manual operation;
　　f, equipped with the same isolation switch short-circuit current carrying capacity of the grounding switch;
　　g, isolating switches and earthing switches between the dual electrical and mechanical interlock, prevent misuse.
