8 way mcb distribution box Introduction:Made of strength ABS and PC material, the enclosure has beautiful appearance, high plasticity and doggedness. LWHA series distribution box is suitable for terminal boxes, distributionpanels, nstrument boxes, electrical equipment boxes and control boxes. Moreover. it is simple and easy to use
1. High temperature reduces the service life of electrical equipment in the 8 way mcb distribution box
The upper limit of the ambient temperature of the electrical equipment designed and manufactured according to the national standard should not exceed 40 when it is working. In summer, the working temperature of the distribution box exposed to the hot sun, direct sunlight, heat reflection from the concrete floor, and heat generated by the equipment itself may sometimes exceed 60. At such a high temperature, it is easy to burn out due to the aging of the insulation of the electric coil and lead. If the electrical contact temperature is too high, the contact resistance increases, the contact resistance increases, and the heat increases. The vicious cycle eventually leads to contact burnout. At the same time, too high temperature will affect the stability of the electrical protection function, the reliability of the operation and the accuracy of measurement.
2. Install the surge arrester only at the inlet. The surge protection cannot cover the entire device
Generally speaking, there are fuses and other equipment between the access line of the distribution box and the bus. When the wire is struck by lightning, for example, the fuse of the wire melts first, then all the distribution box will lose lightning protection. Every year, many distribution boxes are destroyed by lightning.
3. The installation process is incorrect, resulting in overheating of the connector
Some electricians do not press wiring nose when changing lead, with much line wound on nose, the result does not change a line how long, lead burned off again. (William Shakespeare, template, electricity) (William Shakespeare, template, electricity) The distribution box produced by some enterprises, the wire pile screws connected in the bus, the heat is not good, heavy load, natural failure.
4. 8 way mcb distribution box is put into use without inspection, leaving danger for safety
The products provided by the equipment manufacturer were subjected to strict inspection at the factory, but due to road turbulence and unloading vibration, some of the connection bolts may become loose upon arrival at the site, leading to overheating of the lead joints in some outdoor distribution boxes shortly after startup.
5. Improper installation position of distribution box not only affects the appearance of the city, but also is susceptible to external force. It is recommended to choose proper installation position comprehensively.
