Specification:
GCS Low-voltage withdrawable swithchgear is a new-type low-voltage complete switchgear with foreign advanced techniques,it is meeting the rquirements of loadability expansion,computer interfacing,power-control centralization, easy assembly and maintenance.It meets the rquirements of IEC60439 《Low-voltage complete switch equipment and controller 》 GB 7251.1 《Low-voltage complete switch equipment and controller 》standard.

Product feature:
·The frame of the quipment is combination-structure,the fundamental framework is assembled by KS-profiled bar with 20 mm modulus.All structural components are treated with galvanization, and connecting up to form the fundamental framework by self-lock bolt and 8.8 grade hexagon head tap bolt.The internal size of equipment and the sizes of components and isolation compartments could be according to the change of modulus(E=20mm).
·The cubicle is divided into three compartments:horizontal busbar compartment(at the rear end of a cubicle),function unit compartment(at the front of the cubicle),cable compartment(at the bottom of the cubicle or the right hand of fore part of the cubicle).There have galvanized armor plate of high strength flame retardant plastic function boards of part the compartments,and the function of the compartments is independent from each other. There have metal plates with blowholes to insulate the drawers top and bottom,it effectively avoids the electric arc arise from the fault of eectric components and the accidents arise from short circuit of busbar or other circuits.Classified by wire incoming and outgoing:incoming on top and outgoing on top,incoming on top and outgoing at the bottom,incoming at the bottom and outgoing on top,incoming atthe bottom and outgoing at the bottom.The design of the cable make it owns outgoing & incoming channel on top and at the bottom,that solves the question of without outgoing & incoming on top for the old product.
·For reducing the temperature rise of inserts,cable terminals and clapboards,we have designed special transferrer of GCS switchgear,comparing with the same kind of product,the thermal capacity of thistransferrer is increased, and the temperature rise is reduced.
·There have special cable compartment is feeder switchgear and motor control switchgear,the width of it is 440mm.There adopts transferrer or transfer busbar to connect function unit compartment and cable compartment together,it improves the use reliability of cables,and makes the installation and maintenance convenience.
