Speaking of busbars, I believe many people are very unfamiliar. What is a busbar? what's the effect?

Determine environmental conditions There are generally three types of environmental conditions: corrosive environment, normal environment, and special

In the section with fire protection requirements, the cable tray can be added with fire-resistant or flame-retardant boards

The third common problem in engineering design is that the type of cable tray is not marked with the type of anti-corrosion layer, and there is no uni

The material of cable tray is another common problem in cable tray engineering design. According to the material

When the cable tray enters the construction site, the following information should be submitted, the product factory certificate

The load of the cable tray is divided into static load, dynamic load and additional load.

The anti-corrosion materials used in the bridge system and the specifications and quantities of the required straight-through, curved-through, support

The width and height of the bridge should be selected according to the following table, and should meet the cable filling rate not exceeding the speci

The signs of bus failure are bus protection action (such as bus difference, etc.), switch tripping, and sound, light, and signals caused by faults.

The relative humidity does not exceed 50% when the maximum temperature is +40°C; higher relative humidity is allowed when the temperature is lower

The heat dissipation performance of the busway is good. The insulating material of the cable (core wire insulation and outer skin insulation) is both
