GGD series low voltage AC distribution cabinet is designed for use in power distribution systems in power plants, substations, petrochemical plants, industrial and mining plants, high-rise buildings and other facilities for power distribution, in electric motor control centers, for reactive power compensation and other needs of electricity consumers.
GGD series low voltage AC distribution cabinet is designed for use in power distribution systems in power plants, substations, petrochemical plants, industrial and mining plants, high-rise buildings and other facilities for power distribution, in electric motor control centers, for reactive power compensation and other needs of electricity consumers. Used in alternating current distribution systems with a frequency of 50 (60) Hz, rated operating voltage 380 V, rated operating current up to 3150 A for converting, distributing and controlling electrical energy for power equipment, lighting and switchgears.
GGD series low voltage AC distribution cabinet was developed by the Ministry of Energy to promote the technological progress of low voltage distribution equipment in our country and accelerate the upgrade of complete low voltage switchgear. The product is characterized by high breaking capacity, good dynamic and thermal resistance, and high practicality.
GB7251.1 “Low-voltage switchgear and control equipment. Part 1: Type-tested and partially type-tested devices"
IEC439-1 "Low voltage switchgear and control equipment"
The low-voltage AC distribution cabinet of the GGD series is made in a unified cabinet form. The frame is made from cold-formed 8MF profiles with partial welding and assembly and has 20 modular mounting holes, which provides a high degree of commonality.
The GGD series low-voltage AC distribution cabinet takes full consideration of heat dissipation during operation. There are different numbers of ventilation slots at the top and bottom of the cabinet, which creates a natural ventilation channel inside the sealed cabinet from top to bottom, allowing for efficient heat dissipation.
Instrument doors containing electrical components are connected to the frame by stranded copper soft wire. The mounting elements inside the cabinet are connected to the frame using knurled screws, which ensures the creation of a complete protective grounding circuit for the entire cabinet.
The surface of the cabinet is treated with electrostatic spraying, which ensures high adhesion and good surface quality. The entire cabinet has a matte finish, which prevents glare.
The cabinet's degree of protection is IP30.
