Product Introduction

The GGD AC low voltage switchgear is applicable to the AC 50Hzpower distribution system at the rated working voltage of 380V in power plants, substations, industrial and mining enterprisesand other power consumers. The switchgearis sued for power conversion, distribution and control in the power, lighting and distribution device.


The GGD AC low voltage switchgear is a newly-designed product in the spirit of security, economy, rationality and reliability. The product is characterized by high breaking capability, good dynamic and thermal stability, flexible electric scheme, convenient combination, whole series of standardization,general uses, novel structure and high level of protection and so on.

The switchgear is in accordance with IEC 439 “Low Voltage Switchgear and Control Equipment”, GB 7251 “Low Voltage Switchgear” and other standards.

 

Product Features

1. The cabinet door is connected with the frame by the rotary hinge, so installation and dismantlement are convenient. A mountain-shaped rubber plastic bar is embedded at the folded edge of the door. The embedded bar between the door and the frame has certain compression travel during door closing, which can prevent direct collision between the door and the cabinet body, and also improves protection level of the door.

2. The instrument door equipped with the electrical apparatus elements is connected with the frame by several strands of annealed copper wires. The whole cabinet has complete grounding protection circuit.

 

3. The cabinet applies electrostatic spraying process, thus achieving strong adhesion and good texture. The entire cabinet assumes the muted tone, which avoids the glitzy effect and creates comfortable visual environment for the operators on duty.

 

4.The head cover of the switchgear can be removed when needed, so as to facilitate assembly and adjustment of the main busbar at site. Four corners on top of the cabinet are equipped with the hung rings for hoisting and shipping.


5. Protection degree of the switchgear is IP30.
