With the development of electrical, the closed busbars must be selected strictly according to the relevant equipment when selecting them. Then, when choosing closed busbars, what should be chosen according to what?
First, when the closed bus is selected, its relevant parameters of the line pipe should be selected according to the relevant environment, such as the influence of humidity in the environment, and the influence of related electrical properties. Very good corrosion resistance, can be applied to a variety of current and voltage devices, and so on.
The group company currently has four major categories of products: First, power products; Second, bridge bus products; Third, ventilation products; Fourth, composite products. The company's products have been widely used in electric power, transportation, petrochemical, metallurgy, industrial and mining enterprises, urban construction and other industries. It has won the title of "Bright Spot Project" in Luban Award Project, National Excellent and Municipal Excellent Project.
Zhongrui Group has five wholly-owned subsidiaries: Jiangsu Zhongrui Electric Group Co., Ltd., Jiangsu Nanrui Construction Co., Ltd., Nantong Jiangrui Metal Materials Co., Ltd., Jingjiang Jiangrui Air Conditioning Equipment Co., Ltd., Jingjiang Jiangrui Electric Co., Ltd. Limited.
The bridge is the primary carrier in the cable erection. Its raw materials are divided into many types. The bridges used for different cables are different. The bridge will show some problems during the long-term operation, resulting in the cable not working properly. Below, Shaanxi Ximeng Electric Co., Ltd. will take a look at the common problems of the bridges.
There are four major types of problems in the bridge:
(1) The metal bridge and the wire trough and the length of the bracket and its bracket are not less than 2, and are connected to the ground (PE) or zero (PEN) trunk.
(2) Both ends of the connecting plate between the non-galvanized bridges and the connecting plates between the non-galvanized wire troughs shall be connected to the copper core grounding wire, and the minimum cross-sectional area shall not be less than 4 mm2.
