Indoor Outdoor Low Voltage GGD Switchgear Electrical Equipment Power Distribution
production description
The GGD AC low voltage distribution switchgear is applied to
certain distribution system of AC 50/60Hz, rated voltage 400V,
rated current being 3150A or lower, in power plant, transformer
substation, mining enterprise etc, this product is mainly used for
power transforming, distributing and controlling of power
equipment, lighting and distribution equipment.
The GGD AC low-volt distribution switchgear is one new low-volt
distribution cabinet elaborately designed in the light of safety,
economical, reasonable and reliable principle for meeting the
higher demand of energy-source Ministry and majority of electrical
customers. This product owns many advantages as high breaking
capacity, well dynamic, thermal stability, flexible electric plant,
simple combination, strong series performance and printability,
novel structure, high protection rank etc. this product could be
the upgraded product for low-volt complete set switch equipment.
The GGD AC low-volt distribution switchgear conforms with technique
demand of IEC439 low-volt complete set switch equipment and control
equipment and GB7251.1 low-volt complete set switch equipment etc.

Product Features:
The GGD AC low voltage distribution switchgear adopts the form of general switchgear , the frame is welded by 8 MF cold bending steel, and the frame
parts and special supporting parts are processed by NC equipment to
ensure the precision and quality of the cabinet body. The parts of
the general cabinet are designed according to the principle of the
module, and there are 20 mold installation holes, the general
coefficient is high. can make the factory achieve pre-production.
That is to shorten the production and manufacturing cycle, but also
improve the efficiency of work. Heat dissipation in the operation
of the cabinet is fully considered in the design of the GGD switchgear . There are different number of heat emission holes at the upper
and lower ends of the switchgear . When the electrical components in the cabinet are heated, the
heat is raised and discharged through the upper end slot hole,
while the cold air is continuously replenished into the cabinet by
the lower end slot hole, so that the sealed switchgear body forms a natural ventilation channel from the bottom up to
achieve the purpose of heat dissipation. The cabinet door is
connected with the cabinet frame by hinges, without adjustment and
easy installation. The switchgear surface adopts electrostatic spraying, strong adhesion and good
texture. The whole cabinet into a matte tone, avoid glare effect,
for the duty personnel to create a more comfortable environment.
