Product Description


                                 Low Voltage Power Distribution System GGD Switchgear 0


General info


GGD AC low-voltage power distribution cabinet is suitable for power users such as power plants and substation industrial and mining enterprises. It is used as power, lighting and power distribution in AC power distribution system with 50/60hz rated working voltage: 380v (660v) and rated current up to 3150A. The electrical energy conversion, distribution and control of the equipment.


Structural features
1. The cabinet of GGD type AC low-voltage power distribution cabinet adopts the form of universal cabinet. The frame is assembled by partial welding of 8MF cold-formed steel. The frame parts and special supporting parts are supplied by the fixed-point steel production plant to ensure the cabinet. Precision and quality.
2. The design fully considers the heat dissipation problem in the operation of the cabinet, and there are different numbers of heat dissipation slots at the upper and lower ends of the cabinet.
3. According to the requirements of modern industrial product design, the golden section ratio method is used to design the size of the cabinet and each part to make the whole cabinet beautiful and fresh.
4. The top cover of the cabinet can be removed when needed to facilitate the assembly and adjustment of the main busbar on the site. The four corners of the cabinet are equipped with lifting rings for lifting and shipping.
5. The protection level of the cabinet is IP30, and the user can also choose between IP20-IP40 according to the requirements of the use environment.

Structural features:


1. The shell is locally welded and assembled with 8MF cold-formed steel.Mounting holes arranged by E=20mm and E=100mm modules are arranged on the frame to improve the universality of product assembly.The panels and baffles are made of imported cold rolled sheet and adopt pickling, phosphating, electrostatic spraying, anticorrosive process.Cabinet internal treatment using hot dip galvanizing process.In order to strengthen ventilation and heat dissipation, the bottom and upper part of the cabinet have ventilation and heat dissipation holes, and steel wire mesh sealing cover, to prevent small animals to enter.For the convenience of lifting, the cabinet top four corners are equipped with rings.Considering the use of cable outlet, in the bottom of the cabinet set knock hole, and prepare to meet the construction drawing size requirements of the leather line sleeve.


2. When designing the GGD cabinet, the heat dissipation problem in the operation of the cabinet is fully considered.There are different Numbers of heat sink holes at both ends of the cabinet, when the electrical components in the cabinet heating, heat rise, through the upper end of the tank hole discharge, and the cold wind constantly by the bottom end of the tank hole supplement into the cabinet, make the sealed cabinet body from the bottom up to form a natural ventilation channel, to achieve the purpose of heat.


3, GGD ark according to the requirements of modern industrial product modelling design, the method that USES golden section ratio to design cabinet body appearance and the segmentation size of each part, beautiful and easy, face is new.Cabinet door USES turn axle activity hinge and frame to be linked together, installation, disassemble is convenient, the folding place of the door is embedded a hill model rubber model strip, the inlaid strip between door and frame when close the door has certain compression stroke, can prevent the door and cabinet body to collide directly, also raised the protection class of the door.The instrument door equipped with electrical components is connected to the frame with multiple strands of soft copper.Knurled screws are used to connect the installation parts and the frame in the cabinet. The whole cabinet constitutes a complete grounding protection circuit.
