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
