China AC LV Fixed Distribution Switchgear

GGD AC LV fixed type switchgear is applicable to the distribution system

with AC 50Hz, rated working voltage 380V, rated current to 3150A below

in power station, substation, plant enterprise etc., used for power transfer,

distribution and control for power, lighting and distribution devices.

The product has characteristics of high breaking capacity, fine dynamic and

thermal stability, flexible electric project, convenient combination, better

serial practicability, novel structure and high protection grade etc.

It accords with the standards IEC439 Low voltage complete switch

device and control device and GB7251.1 Low voltage complete switch

device etc.
Characteristics

1. The body of GGD AC LV fixed type switchgear adopts universal cabinet type.

framework is assembled with 8MF cold bending bar steel through part welding.

framework components and special mating elements are matched by bar steel

pointed manufactory for ensuring the precision and quality of cabinet. Components

of universal cabinet is designed according to module principle, and with 20 modulus

mounting hole and high universal coefficient.

2. Completely in view of the heat rejection during cabinet running. Heat rejection

slots of different quantities are installed in upper and underside both ends of cabinet.

3. According to the requirements on mold design for modern industry products,

adopting the method of golden mean ratio to design cabinet outline and parting

dimensions of each part, to make the whole cabinet beautiful and decent.

4. Cabinet gate is connected with framework with rotation axis type movable hinge.

With convenient installation and disassembly. One mount type rubber strip is set in

edge fold of gate. Filler rod between gate and framework has certain compression

stroke when closing the gate. It can prevent gate from impacting cabinet directly and

also advance the protection grade for gate.

5. Connect the meter gate set with electrical components with framework by

multistrand soft copper wire. Connect the mounting pieces inside the cabinet with

framework by knurled screws. The whole cabinet constructs complete earthing

protective circuit.

6. Top cover of cabinet can be disassembled if necessary for convenience to the

assembly and adjustment for main bus bar at site. Four squares of cabinet are set

with slinger for hoisting and shipping.

7. Protection grade of cabinet: IP30. User can choose within IP20~IP40 according

to environmental requirements.
