The difference between explosion-proof cable disc and civilian cable disc

What is an explosion-proof cable tray? As the name implies, it is a cable reel with the function of preventing the explosion caused by external explosive gas or other conditions. 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.

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 such explosive gases, the following explosion-proof cable trays must meet the following technical conditions:

1, the length of the cable according to the standard, configured for 30 meters (can be customized length);

2, cable wiring;

3, cable tray rotation need to be flexible, there must be brackets and walking wheels when moving, easy to move;

4. There is an interlock device on the cable tray socket and plug to ensure that it can be inserted and removed after power off;

5. There are instructions on the latches. The grounding contact on the plug is longer than the main contact. When the plug is inserted, the grounding plug is connected first.

When the ground contact comes off;

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.

The difference between explosion-proof cable tray and ordinary cable tray is whether there is explosion-proof function. According to the explosion-proof principle, the main difference between the two is concentrated on the socket panel of the disk. So what exactly are the similarities and differences between explosion-proof sockets and common sockets? Xiaobian to take everyone to find out.

Whether it is explosion-proof type or ordinary type, the basic role of the cable tray is the same, so their outlets all have the same place:

1. The socket panel is equipped with a power indicator. The socket has no power and it can be seen at a glance.

2, are equipped with leakage protection device, ordinary cable tray is an electronic leakage protector or electromagnetic leakage protector, explosion-proof cable tray is a small leakage protection circuit breaker. In the event of a circuit leakage or electric shock, the power can be turned off in the shortest time to protect the safety of equipment and personnel.

3, ordinary socket can be installed waterproof plastic cover, industrial cable tray with industrial waterproof socket, explosion-proof cable tray socket has a waterproof cover, can achieve waterproof and dustproof function.

Because there is one more function than an ordinary socket, there is a clear difference between an explosion-proof socket and an ordinary socket:

1, socket material:

The common cable tray is made of ABS+polycarbon alloy synthetic material, and the socket copper piece is made of 1.0 mm pure copper plate and plated with nickel. The panel and latch shell on the explosion-proof cable tray are made of cast aluminum alloy and the surface is sprayed. Plastic treatment, no static electricity is not easy to oxidation.

2, bolt design:

The length of the contact of the ordinary plug is the same, and the ground contact on the explosion-proof plug is longer than the main contact, so as to ensure that the ground contact state is always maintained during plugging and unplugging, and sparks are prevented. An interlock device is also provided between the socket and the plug to ensure that the plug and socket can only be removed after the power is turned off. The common socket and plug have no such function and design.

The above is the similarities and differences between explosion-proof cable tray sockets and common sockets. Understanding the similarities and differences between the two, on the one hand can help consumers understand the working principle of explosion-proof cable trays and increase confidence in the products; on the other hand, it can also help everyone distinguish between the two at the time of purchase. The difference, so as not to buy wrong, or buy unqualified explosion-proof products.
