GCK, GCL series low pressure shaft cabinet model switchbox are used forelectric motor control central, power distributing centre. They are applied topower stations, electric substations, buildings, edifices, airports, hospitals,industrial and mining establishments as three-phase 50Hz, voltage 380V andas follow electric system suited for the electricity, the feed, the illumination,the motor control and the power compensates. It conforms with the GB7251-97,ZBK36001-89 and IBC439-1 standards.GCK, GCL switchbox skeleton is made from "FA28" model material or "c" modellow-alloy channel steel. The main bus stood parallel to the top of cabinet, doorsealed by silicon adhesive tape, on the upper and lower part of cabinet havetrepanning for ventilation or heat exchanger systems.Technical parameters:1) Main circuit nominal insulation voltage: 660V2) Main circuit nominal voltage: AC 380V3) Auxiliary circuit nominal voltage: AC 220V, 380V, 110V4) Rated frequency: 50 / 60Hz5) Rated current:a) Level bus: ≤3,200Ab) Vertical bus: 1,600A6) Nominal short time withstand current (IS): 50kA, 80kA7) Nominal peak reliability current: 105kA, 176kA8) Power frequency test voltage:a) Main circuit: 2,500V/minb) Auxiliary circuit: 1,760V/min9) Peeling levels of protection: IP3LO, IP4LO10) Protection:a) In circuit design, operating power source adopted electric move measure(with isolation transformer)b) In mechanism design, we set much value on design between cabinet andinsulating; it up to IP40 standards provided by IEC529 and GB4208 andgives a guarantee for personal security of fixing, mending and operatorUsage conditions:1) Working altitude limit: 2,000m2) Indoor, no dust, aggressive gas or rain3) Ambient temperature and relative humidity: no higher than 40°C, no lowerthan -5°C, average temperature limit of 35°C, relative humidity limitof 85%4) No shock and bump5) Fixing inclination pitch is not over 5%
