Product description

GGD ac low voltage distribution cabinet is suitable for power users such as power plants, substations, industrial and mining enterprises to ac 50Hz, rated working voltage 380V, rated working current 5000A power distribution system, as power, lighting and power distribution equipment power conversion, distribution and control.

The product has the characteristics of high breaking ability, good dynamic and thermal stability, flexible electrical scheme, convenient combination, strong practicability, novel structure and high protection grade.It can be used as the replacement of low-voltage switchgear assembly.

GGD ac low voltage distribution cabinet conforms to IEC439 "low voltage switchgear and control equipment", GB7251 "low voltage switchgear" and other standards

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.

Conditions of use

1. Ambient air temperature shall not be higher than +40℃ and not lower than -5℃.The average temperature within 24 hours shall not be higher than +35℃.

2. Indoor installation and use, the altitude of the use site shall not exceed 2000m.

3. The ambient air relative humidity shall not exceed 5% when the highest temperature is +40℃, and it shall be allowed to have a large relative humidity at a lower temperature.(for example, 90% at +20℃) the effect of occasional condensation due to temperature changes should be taken into account.

4. The inclination of the equipment with the vertical plane shall not exceed 5%.

5. The equipment shall be installed in a place free from violent vibration and impact, and in a place not strong enough to cause corrosion of electrical components.
