GCK, GCL Series Low Pressure Shaft Cabinet Model Switchbox
GCK, GCL series low pressure shaft cabinet model switchbox are used for electric motor control central, power distributing centre. They are applied to power stations, electric substations, buildings, edifices, airports, hospitals, industrial and mining establishments as three-phase 50Hz, voltage 380V and as 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.Constitutional features:GCK, GCL switchbox skeleton is made from "FA28" model material or "c" model low-alloy channel steel. The main bus stood parallel to the top of cabinet, door sealed by silicon adhesive tape, on the upper and lower part of cabinet have trepanning for ventilation or heat exchanger systems.Main 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) Peel level of protection: IP3LO, IP4LO10) Degree of protection:a) In circuit design, operating power source adopted electric move measure (withisolation transformer)b) In mechanism design, we set much value on design between cabinet andinsulating; it up to IP40 standards provided by IEC529 and GB4208 and gives aguarantee for personal security of fixing, mending and operatorUsage condition:1) Working altitude limit it of 2,000m2) With indoor no dust, aggressive gas and rain attack3) Ambient temperature and relative humidity: no higher than 40°C, no lowerthan -5°C, the average temperature limit of 35°C, relative humidity limit of85%4) No shock and bump and the fixing inclination pitch no over 5%
