In the design of GGD cabinet, the heat dissipation problem in the running of the cabinet is fully considered. There are different number of heat sink holes at both ends of the cabinet, so that the sealed cabinet form a natural air duct from bottom to top, to achieve the purpose of heat.
GGD cabinet is designed according to the requirement of artistic modelling of modern industrial product, use golden section ratio designs the appearance of cabinet, make the whole cabinet beautiful and elegant.
The cabinet door is connected with the cabinet body by the movable hinge of rotating shaft, which is convenient for installation and disassembly. The folding edge of the door is embedded with a rubber, which can prevent the door from direct collision with the cabinet body and improve the protection grade of the door.
The GGD cabinet selects HD13BX and HS13BX rotary operation knife switch, which makes the cabinet operation door can be opened, easy to manufacture and maintenance.
The top cover of the cabinet can be removed when needed, Easy to assemble and adjust the main bus line on site. The four corners on the top of the cabinet are equipped with lifting rings for lifting and installation

1. Normal working environment:
Switchgear should be installed in a clean, non-corrosive, non-strong vibration or impact, dry and well ventilated room.The altitude ≤ 2000m.If altitude more than 2000m, the equipment should be operated with corresponding capacity reduction.
Atmospheric conditions: the air is clean, the relative humidity does not exceed 50% at the highest temperature, and higher phase humidity is allowed at lower temperatures (e.g., 90% at +20°C), but it should be considered that temperature changes may occasionally produce condensation, so the device should increase ventilation or heating measures.
Installation inclination shall not exceed 5 degrees;
2. Environment temperature:
Maximum air temperature +40°C;
24 h maximum mean temperature +35°C;
Minimum temperature -5°C.
When the equipment is used above the ambient temperature, capacity reduction operation shall be considered.
