【GCK (GCL) low chest of drawers】

GCK low chest of drawers is the introduction of day pass by our factory product technology, combined with plant process characteristics, self-developed national conditions, with high technical performance indicators, to fit the development needs of low-voltage electricity market drawers, the device was 199 five years in the National Testing Center of Jiangsu Province low-voltage electrical product quality inspection station in type testing. The product is suitable for the needs of a variety of power supply and can be widely used in petroleum, chemical and other industrial and mining enterprises distribution system.

1, the main features

Switchgear cabinet structure by a thin steel plate into pieces, using a combination of bolts, the main busbar room upper cabinets, lower for the two parts, the front part of the pallet into the small room, so isolated from each loop. The pallets have a skeleton movement for drawer rails, and can be installed secondary circuit isolation outlet, the back part of the equipment and the inlet and outlet branch bus terminals, etc., branch bus lay vertically from top to bottom, respectively, with primary, secondary, Isolated socket connection, the main bus and branch bus are insulated with high-strength support and fixed in cabinet row last.

2, switch between its door and the cabinet with a soft touch technology, not only improves the level of protection but also in the door will not open and close when the collision Ershi cabinet paint off hard surface.

3, functional unit cabinet drawer installation points, plug-and fixed three, each circuit is an independent unit, cell doors and between the circuit with mechanical interlock to ensure the maintenance of security and operational safety, The circuit of electrical components are installed in the small room on the drawer, the main circuit of the power supply out of two were rated current of 250A of the connectors to complete the secondary circuit connected by sliding connectors, each drawer can be installed up to 24 , the rated current of 10A the left side of the drawer when pushed into place directed a "test" position, then the second loop has been connected to non-stress test for unit movements, slightly lifting the drawer further advance, until the pallet has been withheld , left instructions "on", then the main loop has been connected, service, lift the drawer when pulled out slightly about three-quarters, the drawer is in custody, this time can be used for cabinet repair, remove the drawer For and a further lift the drawers pulled out, the operation very easy.

4, the same specifications to ensure interchangeability drawer.

5, cabinet total height 2200mm, respectively, 180,200,220,440,880 small room height of four, each 200mm drawer cabinet can hold up to 9, the effective installation of small room size is 1760mm, 180mm small room for the capacitor control unit used. 600,800,1000 mm cabinet width, respectively of three, counter depth size of 1000mm, but can be customized processing cabinet deep 800mm.

6, door and drawer surface is 2mm high-quality cold-rolled sheet, the main columns and beams with 3mm premium cold plate.

7, all the cold plate surface passivation treatment by phosphating paint or spray, galvanized iron components (colored).

8 lap surface is embossed copper, tin, silver vertical static contact arrangements, plus a thermoplastic pipe jacket, copper 98% copper content, plus a transparent sealed outlet circuit board.
