GCK switch cabinets/Switchgear panel
GCK switch cabinets/Switchgear panel apply to the exchange of 50HZ, rated insulation voltage 380V low-voltage distribution system as affected by electricity, feed, the mother Union, lighting, motor control and power compensation purposes, which includes Power Center (PC) and the Motor Control Center (MCC) the function and can be designed as a fixed cabinets and drawer cabinets hybrid systems to meet the needs of the different power supply.
GCK Switchgear panel for the whole assembly-type composite structure, the basic framework with specific profiles, assembly formed.
2. Enclosure skeleton, part dimensions and hole size according to the basic module, E = 20mm change.
3. In the MCC program, Switchgear panel parts into five areas (rooms): the level of bus zone, vertical busbar area, functional unit area, cable rooms, neutral grounding bus zone. District of mutual isolation, to ensure normal operation of line, effectively preventing the failure to expand.
4. Since all structures Shelves are sturdy self-tapping locking screw connection is made to avoid the welding deformation and stress, improve accuracy and grounding continuity.
5. Good versatility, adaptability, a high degree of standardization.
6. Functional unit (drawer) is out, insert as a lever action, 320mm Following a single drawing board, 400mm above the upper and lower pairs of pull pull, rack configuration roll
Dynamic bearing operating light and reliable.
7. MCC drawer has eight kinds of standard sizes, namely:
8. PC program, each one to three cabinets can be mounted air circuit breaker.
9. MCC program in the second couplings, in the docking mode of use of mobile rail-oriented, to ensure interchangeability of modules, while the functional units can be used in accordance
10. This Switchgear panel is out type switch cabinet and other comparative features of compact structure, high strength, high-performance, safe and reliable and so on.
11. Framework, doors and so on with epoxy powder coating electrostatic spray insulation is good, durabletion
