GCK(L) LV withdrawable switchgear cabinets

General
GCK(L) LV withdrawable switchgear cabinets applicable to the low voltage distribution system with AC*0Hz, rated working voltage **0V. It contains power center (PC) and motor control center (MCC) functions. Each technical parameter all reaches national standards. With characteristics of advanced structure, beautiful appearance, high electric performance, high protection grade, reliable and safe and easy to maintain. It is the ideal distribution device for low voltage power supply system in metallurgy, petroleum, chemical, power, machinery and light weaving industries etc.
The product accords with standards IEC***9, GB***1.1.

Characteristics
1. GCK(L)1 and YFGCJ1 are assemble type combined structure. The basic skeleton is assembled by adopting special bar steel.
2. Cabinet skeleton, component dimension and starter size change according to basic modulus E=*5mm.
3. In MCC project, parts in cabinet are divided into ve zones (compartment): horizontal bus bar zone, vertical bus bar zone, function unit zone, cable compartment, and neutral earthing bus bar zone. Each zone is separated mutually for circuit's normal running and effectively preventing fault expansion.
4. As all structures of framework are connected and firmed by bolts, so it avoids the welding distortion and stress, and upgrades the precision.
5. Strong general performance, well applicability and high standardization degree for components.
6. Draw-out and insert of function unit (drawer) is lever operation, which is easy and reliable with rolling bearing.

Conditions for normal operating environment
1. Altitude above sea level should not exceed ***0M.
2. Ambient air temperature: *5℃~**0℃ and the average temperature should not exceed **5℃ in *4h.
3. Air condition: With clean air. Relative humidity should not exceed *0% at **0℃. Higher relative humidity is allowed at lower temperature. Ex. *0% at **0℃.
4. Places without re, explosive danger, serious pollution, chemical corrosion and fierce vibration.
5. Installation gradient not exceed 5℃.
6. Control center is suitable to the transportation and store with following temperature :**5℃ ~**5℃, in short time (within *4h) it should not exceed **0℃.
