GW23B-252D(G) is  three-phase  AC 50 hz outdoor  high-voltage equipemt for cutting off or connecting circuit without load to change high-voltage circuitry and mode. It

can safely create electric isolation on repaired generatrix, breaker and some high-voltage equipment.

The product is double-column level-fracture open-air folding  type that annex with JW10-252 earthing switch on one side or both sides, disconneting switch adopt SRCJ3 type three pole catenating mechanism, earthing switch adopt SRCS1type three pole catenating mechanism.

Product feature :

The strucure is level-fracture standing open-air folding, phase

distance is short

After separating brake, occupied upper space is small. It is suitable for inlet and outlet of line disconnection switch. Two sets product compose dual static contactor proper for 1.5 times wire, save the area. It also can compose the open-air composite apparatus with transformer. Conduct tube adopt aluminum alloy with high strength, high conductivity,Light weight,  high intensity, good anti-erosion.

   Dynamic contactor is insert-type, with ability of self-cleaning. One end of U contact finger of static contactor is fixed on the contact finger socket that create securing contact, reliable conduct

   Rotating parts adopt staimless pin axis, self-libricate bearing, stainless bearing joint bearing

all colour metal parts use hot-dip galvanizing.

   Earthing switching is one-step action type, simple structure, convenient maintenance, make fiily  use of electrodynamic to clamp contactor and keep knife on the position of closing, endurance to high-currency is strong, parameter of switching indutive currenty is high. 

   Driven rod adopt assembly type without cuting welding at he site, rod is made from hop-dip galvanizing steel pipe.

    Interlock between main knife and earthing knife apply structure of cam slide, action is direct, interlock is reliable.

   Operating mechanism box is made from stainless plate with riveting , non-welding that has elegent shape. Eletric mechanism apply vaccum decelerated box and nylon-gear box,  calm and stable, adopt foreign-brand electric component, block function is completed.

  Manpower setup take advantage of relay inside box to implement function of electromagnetic lock, reliable interlock, overcome shortage of rust and action failure from  electromagnetism lock used by home customer.
