Yawei low-voltage switchgears can be used for power conversion, distribution and supply of electricity distribution systems with the alternating current of 50Hz, the rated power of 380V and the rated current of 3150A. The low-voltage switchgear is widely used by power plants, substations and other industrial users. It is one of our bestselling products for advantages of high breaking capacity, flexible circuit combination and reliable operation.

Features

The switchgear cabinet is made of col-formed steel. All the components are produced by our company with modular design and general use;
To improve heat dissipation, the cabinet has ventilation holes at the top and bottom. When the interior electric components are working, the heat will be discharged through the top holes while the cool wind will be blown into the cabinet through the bottom holes, forming a ventilation circuit for the cabinet;
The cabinet is delicately designed and manufactured according to the golden rario;
The panel consisting of electrial components is connected to the cabinet frame with soft copper wires. And other interior components are installed and connected to the frame with knurled washers. The cabinet has a complete earthing system;
The outerior surface of the cabinet is painted with polyster orange-peel baking paint or treated with powder coating. The treated cabinet surface turns to out be matte, creating a visually friendly working environment for operators;
The cabinet’s top cover can be removed for the busbar installation and adjustment. The cover also has a ring at each corner for the convenience of cabinet hoisting and transport;
The cabinet reaches IP30 rating. IP20-40 is also available for customers according to the working environment.

Installation Conditions

Temperature: -5~40℃; the average temperature within 24 hours≤35℃；
Altitude≤2,000m for indoor applications;
Humidity≤50% when the temperature is 40℃; high humidity is allowed when the temperature is low; occasional condensation should be accounted for due to temperature changes;
Less than 5 degrees of tilt against the vertical;
The cabinet should be installed in an area without strong vibration and impacts as well as corrosive substances.
