"According to statistics, there are about 90,000 fire accidents every year, 30% of which come from inferior sockets. Every year, about 8,000 people are electrocuted and 30% come from inferior sockets. Electricity safety accidents occur from time to time."
Many workers on construction sites accidentally get electrocuted because of the following three reasons.
1. There are serious potential safety hazards in the distribution box on each floor of the construction site.
2. The cable used by electric pickaxe does not meet the requirements.
3. Workers' labor protection does not meet the requirements.
2. The cable used by electric pickaxe does not meet the requirements.
3. Workers' labor protection does not meet the requirements.
We realize that bad plugging is only the trigger factor of this accident, and improper temporary electricity use is the essential cause of this safety accident.
Therefore, in the construction work, what should I do if I want to use electricity temporarily?
Requirements for temporary power consumption on construction site
1. The distribution box and switch box should be installed in a correct, firm and mobile box on a solid support. The vertical distance between the lower skin of fixed distribution box and switch box and the ground should be no more than 1.3m and no more than 1.5m.. Mobile distribution box and switch box are made of iron plate or high-quality insulating material. The thickness of the iron plate should be greater than 1.5m.
2. The main distribution box should be located near the power supply, and the distribution box should be installed in the area where the electrical equipment or load is relatively concentrated. The distance between the distribution box and the switch box should not exceed 30m, and the horizontal distance between the switch box and the fixed electrical equipment it controls should not exceed 3m.
3. The switch box should have the final distribution box, and there should be one switch and one leakage in the switch box. Each power consumption device should be equipped with its own switch box. It is strictly forbidden to directly control two or more electrical equipment with one switch apSSSSSSSSSSSSSSSSSSSSSSSpliance.
In addition, if the plug power socket presents errors in installation and application, it will also lead to various problems, which will endanger the application and safety afterwards.
1. Wrong cable selection
For power sockets with plugs not up to rated voltage, the cable sleeve of industrial plugs can only use cables with inevitable diameter limitations. If the diameter of the cable is too small, it is impossible to improve the sealing performance of cracks, and thus the results of antifouling and moistureproof can not be achieved. Especially outdoors, precipitation is likely to go down the cable to the inside, damage the insulation layer, and it is easy to conduct electricity or short circuit. NANTE's plugs and sockets are provided with IP44 protection level, anti-pollution and moisture-proof, so you don't have to worry about conduction or short circuit failure.
The sheath of the cable is too long, not the cable sheath, but two copper-core cables clamped. It is easy to damage the cable or the clamp is too loose. If the cable is broken, please turn off the power supply for a short time, or the short circuit fault will continue when it is more serious. In addition, there are two copper-core cables outside the cable sheath, which cannot be sealed. It is also effective to use several cables or several cables to pass through and wire together, which will also lead to the same problem. Similarly, the connection between the plug and the RF adjacency device must be a cable with the required diameter, and two single-core cables cannot be replaced at will.
2. The screw on the terminal is too loose.
The terminal screw of the plug or socket adjacent to the flat cable is locked. If you don't pay attention, the screw is too loose, which will easily cause arcing or increase the resistance of the plug and transmission line loop. If it is more serious, the terminal will get hot and damage the power socket.
During the whole disassembly and assembly process of plug power socket, especially in the stressed parts such as plug seat and plug shell, socket and power socket, the rear seat lock is too loose, which is easy to loosen or break during the whole plugging and unplugging process, and even causes the screw hole to be crushed.

3.the cable sealing ring is not installed correctly
Remove the plug and forget to reinstall the cable sealing ring, or the cable is not tightened, which will have poor anti-pollution and moisture-proof ability.
4.the power socket did not pay attention to the target on time.
Socket waterproof box outline installation socket scanning number is fixed on the inner wall or shelf, and the installation position should be paid attention to. Generally speaking, there should be a healthy groove under the power socket. After the plug is put in, the cable will loosen along the road.
Under the outdoor premise, if the socket is installed outside the power distribution cabinet, it will be exposed to the sun and rain for a long time, which will accelerate the embrittlement of the power socket with plastic shell and endanger the service life and safety.

In view of the above problems, if you are not comfortable with the quality of those plugs and sockets in the market, then you can choose NANTE Electric. We have been in this business for more than 30 years, and the customers who have consumed it are obvious to all.
