Model meaning


Structural characteristics

The product design has fully considered the requirements of the majority of power users and design departments, which can meet the needs of the developing power industry such as the centralized control of capacity increase power, convenient installation and maintenance, and shortened accident treatment time, etc., which is safe, economical, reasonable and reliable. The product has the characteristics of strong connection ability, high breaking ability, good dynamic stability, flexible electrical scheme, convenient combination, strong series and practicability, and novel structure, etc. It is an updated product of low-voltage stationary switchgear in China. At the same time, it can be combined with drawers and cabinets for mixed use. 

Basic structure:Switch cabinet cabinet structure is composed of profiles (module E=25mm) assembly. As a result of using lock since tap screw and 8.8 class high strength bolt for connection, so the cabinet high precision, good sex. Cabinet body appearance and internal separation. 


Working conditions

1.The ambient air temperature shall not exceed 40°C, and the average value measured within 24 hours shall not exceed 35°C, with the minimum ambient air temperature of -S"C; 

2. The elevation of the installation site shall not exceed 2000m;

3. The surrounding air is not visibly polluted by dust, smoke, corrosive gases or flammable gases, vapors or salt spray;
