Galvanized wire is divided into hot dipped galvanized wire and cold galvanized wire (Electro Galvanized Wire). Galvanized wire has good toughness and flexibility, the maximum amount of zinc can reach 350 g /sqm. With zinc coating thickness, corrosion resistance and other characteristics.

We know that industrial electricity consumption is very large, and the amount of industrial cables is also very large. The issue of the safety of cables and cable trays is the primary consideration when selecting products. How does the explosion-proof cable tray achieve explosion-proof function?
We come to understand the environment that may cause an explosion. According to the frequency and duration of the occurrence of explosive gas mixtures in China, the explosive gas environment is divided into three major regions: Zone 0, Zone 1 and Zone 2. Zone 0 represents the environment where explosive gas mixtures will occur for a long time and continuously. This environment generally exists only in highly concentrated containers of mixed gases. Therefore, the environment faced by explosion-proof cable trays is usually an environment in which explosive gas may occur or is unlikely to occur. There is an environment that exists only for a short time even if it appears.
In order to solve the possible short-term hazards caused by this type of explosive gas, the following explosion-proof cable trays must meet the following technical requirements (taking the explosion-proof cable tray produced by Yelang Electric as an example):
1, the cable length according to the standard, configured for 30 meters;
2, cable wiring;
3, cable tray rotation need to be flexible, there must be brackets and walking wheels when moving, easy to move;
4. The cable tray socket and plug are equipped with interlocking devices to ensure that they can be plugged and unplugged after a power failure. 5. The latches have a disconnection instruction. The grounding contact on the plug is longer than the main contact. When the plug is inserted, the grounding plug is connected and pulled out. When the ground is removed, the contact is detached;
6. The material of cable drum and explosion-proof bolt shell is cast aluminum alloy, and the surface is sprayed;
7, the cable tray can be equipped with leakage protection miniature circuit breakers.
Correct understanding of what is called explosion-proof cable helps safeguard industrial production safety. In the industrial production process, the use of electricity safety protection requires not only careful construction by the construction personnel, but more importantly, the selection of industrial electrical appliances that meet the specifications and requirements. Explosion-proof cable trays are an important part of safeguarding industrial production and electricity safety. Be sure to look for brands and specifications when choosing.

Cable routing.
What is explosion-proof cable tray <br> <br> the name suggests, is a burst prevention function due to external explosive gases or other circumstances caused by the cable tray. Ordinary people may be unfamiliar with cable drums, but if you compare this with the electrical appliances that are commonly used in our daily lives, you may suddenly realize that. Take the example of a power outlet that we are used to. For example, cable trays are industrial sockets.
