Features

1. The skeleton adopts special-shaped steel plates, uses three-dimensional positioning, and bolts to connect the welded structure, thereby avoiding welding stress deformation and improving installation accuracy.

2. The internal structure mounting parts are made of galvanized steel plate or aluminum-zinc coated plate, which is not easy to be oxidized or rusted. The door panels and side panels around the switch cabinet are made of high-quality steel plates and electrostatically sprayed.

3. The frame and component installation modulus is 20mm.

4. The drawers adopt a standard modular design with strong interchangeability, which can meet various technical solutions of customers to the greatest extent.

5. Each cabinet in the switchgear is divided into three rooms, namely busbar room, functional room and cable room. can be used), the cable room is located at the back of the cabinet, and the functional units and each room inside the cabinet can be separated.

Working Environment

1. The altitude does not exceed 2000M.

2. The short-term maximum temperature is 40°C, the 24-hour average maximum temperature is 35°C, and the minimum temperature is -5°C.

3. The annual average relative humidity of the air is not more than 90%.

4. Places without obvious severe vibration, impact and bumps.

5. There are no flammable and explosive materials, and there is no gas and conductor dust in the surrounding air that can corrode metals and damage insulation.
