General info
Houndreds types product as like GCK low-voltage withdrawable
switchgear (PC) by the power distribution center tank and motor
control center (MCC) of two parts, is suitable for power plant and
substation industrial and mining enterprises and other power users
as ac 50 hz, maximum voltage to 660 v, the maximum working current
- 3150 - a power distribution system, as power distribution, motor
control and lighting power distribution equipment such as electric
energy conversion distribution control.
Houndreds types product as like GCK low-voltage withdrawable
switchgear with high breaking capacity, good thermal stability,
advanced structure, reasonable, electrical scheme of practical
series, strong commonality, various solutions unit in any
combination, a cabinet put oneself in another's position to
accommodate the circuit is more, save area, beautiful appearance,
high protection grade, safe and reliable, and convenient
maintenance.
This product conforms to IEC439 standard, also conforms to
gb7251.1-2005 (national standard of low-voltage switchgear
assembly) and zbk36001-89 "professional standard of low-voltage
draw-out switchgear assembly".
Structural features:
1. The cabinet frame adopts C profile, bolt connection without
welding structure so as to avoid welding deformation and stress,
and improve the installation accuracy.
2. Internal structure shall be galvanized.After pickling and
phosphating, the exterior was sprayed with electrostatic epoxy
powder.
3. (PC) in the center of the power distribution ark into line,
busbar area across the top level, lower level of busbar area for
circuit breaker, the breaker can be configured homebred CW1, HSW1
series, can also according to customer's need to configure the
foreign electric company production of various kinds of circuit
breaker, such as ABB company E series circuit breaker, as well as
intelligent circuit breaker and so on.
