Product Introduction:

GGD type AC low-voltage distribution cabinet is suitable for power distribution system with ac 50Hz, rated working voltage 380V and rated working current 3150A for power users in power plants, substations, factories and mining enterprises, petroleum, chemical industry, metallurgy and textile. Power conversion, distribution and control for power, lighting and distribution equipment.
This distribution screen conforms to IEC439 "Low-voltage Complete Switchgear and Control Equipment", GB7251 "Low-voltage Complete Switchgear and Control Equipment" and other standards.
GGD TYPE AC low voltage distribution cabinet has the characteristics of high breaking capacity, good dynamic and thermal stability, flexible electrical scheme, convenient combination, seriality, strong practicability, novel structure and high protection level.
The basic framework of the distribution cabinet is a combination of prefabricated structure. The main structural parts of the framework are connected to each other through screw fastening to form the basic framework. According to the need, the door, baffle, baffle, mounting bracket, bus bar and electrical components and other parts are added to form a complete switch cabinet.
The cabinet body adopts the form of general cabinet, and the structure is formed by local welding of 8MF(or C profile) cold bending steel.
General parts according to module principle design, framework and parts installation hole by module E=20㎜, general coefficient is high, can make the factory achieve pre-production, not only shorten the production cycle, but also improve the work efficiency.
The internal components are galvanized, and the external parts are pickled and phosphated and then sprayed with electrostatic epoxy powder.
Natural ventilation Windows are provided at the bottom and top of the switch cabinet without reducing the protection level of the shell.
 
service conditions:
