How to prevent fires caused by overloading wires and cables?

- Oct 12, 2019-

1. In the circuit design process, the capacity of the site should be accurately verified, and the possibility of adding capacity in the future should be fully considered, and the appropriate type of wire and cable should be selected. Large capacity, should choose a thicker wire and cable. Circuit design and reasonable selection are the key steps to prevent overload. If the design is not properly selected, it will leave a congenital hidden danger that is difficult to rectify. Some small projects and places are not carefully designed and selected. It is very dangerous to choose and lay the line at will. New electrical appliances and electrical equipment should fully consider the bearing capacity of the original line. If the original line does not meet the requirements, it should be redesigned and modified.


2. The line should be laid in accordance with the relevant specifications and allowed to be laid by an electrician qualified personnel. The laying conditions of the line directly affect the heat dissipation of the wire and cable. Generally speaking, the laying of the line should not pass through the easy, combustible materials, stacking, which will lead to poor heat dissipation of the wire and cable, heat accumulation, the possibility of igniting the surrounding combustible items, and increase the risk of fire caused by overload. . The lines laid in the ceiling of public entertainment venues shall be protected by steel pipes so that the ceilings are separated from the lines. In the event of overload or short circuit, even if there are beads, they will not fall and avoid fire.


3. Accelerate the renovation of old lines and eliminate fire hazards. Old enterprises, old residential areas and other units, due to the long time of use, many lines have been aging, exceeding the service life. Even if the current carrying capacity of some lines is not large, the aging line is difficult to withstand such current carrying capacity, and it also has the danger of overload. Especially in the old residential areas, the lines have long since aging, but with the improvement of people's living standards and the increase of household appliances, their electricity consumption is still rising year by year, which is really worse. For old lines, we should promptly supervise and coordinate, and promote their rectification as soon as possible to eliminate fire hazards and ensure safety.


4, strengthen the use of electricity management, to avoid messy wiring, messy lines, use mobile sockets with caution. Indiscriminate wiring, chaotic wiring, and the use of mobile sockets are actually adding electrical equipment to a certain line, increasing the amount of current and possibly causing overload. The mobile socket jack is obviously more than the fixed socket on the wall. If too many electrical equipment is used on the mobile socket, the original line must be unbearable. For larger power equipment and electrical appliances, separate lines should be provided, and mobile sockets should not be used as wiring sources.


The above is the summary of the prevention of wire and cable overload for everyone to pay attention to, safety is no small matter. Junhao wire here to remind everyone to use or purchase wire and cable must be based on actual requirements to choose the appropriate wire and cable to avoid wire and cable A safety incident that occurs due to overload.
