GCS Low-voltage Withdrawable Switchgear Cubicle  (large number) | | |
 Product Feature | GENERAL
It is suitable for power distribution system of power plants,oil and chemical industry,metallurgy industry,textile industry and high buildings especially in the place where requires for high automation and connection to computers such as large power plants and petro-chemi-cal industry.it adapts to 3-phase system with frequency 50(60)Hz,rated voltage 380V (400),(660), rated current 4000A max,and is used for low voltage distribution equipment of power supply system,motor contol center and reactive power compensation.
STRUCTURE
1. The main structure is made of shaped steel of type 8MF with two mounting holes(m=20mm,100mm,and diamet-er-9.2mm) on both sides.It is flexible and convenient to assemble.
2. The function units are diveded into three compartment:function compartment,busbar compartment,busbar compartment and cable conpartment,each has independent function.
3. The horizontal busbar arrange in parallel at the back of cubicle to strength their resistance to electeic power,which is the basic measure to make main curcuit have high intensity of short circuit.
4. The design of disconnected unit for cable makes it convenient for cable's use.
