FEEDBACK

GCK Low-voltage Switchgear Panel, Withdrawable type

Application: mainly applicable in places with high automation and need to communicate with computer, like large power station and petrochemistry system, as the low voltage distribution device of the distribution and motor controling, and reactive power compensation in power system.
Protection degree: IP30, IP40. Bus type: three phase four wires, three phase five wires. Operation type: in-place, long-distance and automatic
Standard: IEC60439-1

Selection

Operating conditions

1. Ambient air temperature: -5℃ ~+40℃ .
Daily average temperature: ≤35℃ .
When the actual temperature exceed the range, it should be used by reducing the
capacity accordingly.
2. Transport and store temperature: -25℃ ~+55℃. do not exceed +70℃ in short
time.
3. Altitude: ≤2000m.
4. Relative humidity : ≤50%, when temperature is +40℃ .
When temperature is low, larger relative humidity is allowed. when it is +20℃,
relative humidity can be 90%. Since the temperature change will make out
condensation.
5. Installation inclination: ≤5%
6. Applicable in the places without corrosive and flammable gas.
Note: Customized products are available.

Feature

GCK panel is combination structure with bolt. The complete panel is compose of door, terminal board , baffle plate ,supporting frame and drawer, busbar, etc.
Basic frame adopts FA28 type or KB type (Ctype) to combine with together. Total structural components of frame are connected by self-tapping screw.
It should add to door, face place, baffle plate, supporting frame and drawer to finish completed panel by requirements.
The installation hole of body and components modules E=25mm change,flexible and convenient to install.
Drawer unit height divide into ½ unit, 200mm, 300mm, 400mm, 500mm, and 600mmm series. The loop current decide the drawer height,virtual installation height is 1800mm.
GCK panel withdrawable function unit adopts special push (pull) mechanism, light
structure, perfect interchange. It indicate of working position, test position and
isolating position mechanical locking condition. Install additional pad lock for operating handle.
The frame and inner metal components are galvanized to assure reliable earthing .
GCK basic frame is combination assembly type structure, adopt standardized module design. for combination assembly type structure, the standard module design.
Compact structure, flexible assembly, can be assembled into a protection, measurement and control, indicating etc. standard unit, Can choose assembly according to requirement, To form different frame Features and drawer unit.
1. The cabinet frame
C type material adopted for the mainframe, Frame parts and Special parts will be provided by our company to make sure the accuracy and quality.
● Parts forming size, hole size,Equipment interval adopt modularization. (E=25mm)
● The internal structure should be galvanized.
● The top cover is detachable,horizontal bus can be installed easily after removing the top cover, Hand ring
● External phosphating treatment; Then use electrostatic epoxy powder coating.
● Cabinet frame is divided into the busbar compartment, functional compartment, the cable compartment three separate interval, Can prevent accidents diffusion and convenient charged repair.
2. Functional unit (Withdrawable part)
● Functional unit: Feeder unit , Motor unit,utility power unit.
● The high modulus of drawer unit is 200mm, include 1/2unit,1unit,2 unit,3 unit four size series.
Unit loop rated current below 630A.
● Each MCC Cabinet can install 9 set drawer with 1 unit , or 18 set drawer with ½ unit .

● The compartment door plate is interlocked between operating mechanism and drawer, the door can be open until the main switch is on the close position
● The main switch operating mechanism can be locked in close or open position by a padlock , the equipment can be maintained safely.
● There are main circuit outlet plug,auxiliary circuit secondary plug and earthing plug at the back of function unit.
● The earthing plug make sure the protection circuit continuity when drawer on Separation tests connection position.
● Functional unit compartment by metal partition board.
● Compartment valve, can be open and close automatically, with drawers pushed and pulled so that in the compartment without touching the vertical busbar.
3. Busbar system
● Vertical bus uses polycarbonate engineering plastic shell sealed
● GCK, GCL busbar system use 3P4W, 3P5W, Horizontal busbar will be installed at the top of cabinet, N phase, PE phase. Can be installed on the top of the cabinet, and can also be arranged in the cabinet bottom.
