What are the precautions for cable installation
Nowadays, in order to make the interior more beautiful, especially in the renovation of water and electricity, the pipes and wires are hidden in the wall. However, if the wires are hidden in the wall for a long time, the problem of wire aging will occur, and even PE Cable will burn out. Danger, so what are the precautions for wire installation?
- The correct connection method
In the process of laying out the wires, it is necessary to avoid the appearance of joints, because relatively large resistance is very easy to appear at the joints, and it will also cause the phenomenon of heating of the wires. If it is unavoidable that joints will appear, use insulating tape outside the joints.
- Choose a reasonable installation method
There are two ways to install wires in the room: exposed installation and concealed installation. The exposed installation is actually laid along the wall, ceiling surface, truss beams, roof pillars, etc., you must pay attention to the installation of the family’s self-exposed installation. Do not squeeze and fold the wires excessively. Concealed installation is to lay in the wall or in some places inside the ceiling, but the concealed installation is best operated by professionals.
- Scientifically choose the thickness of wires
Specific electrical power needs to be combined with appropriate Electrical cables. If high-power electrical appliances use thin wires, it will heat the wires, shorten the service life of the wires, and even break down the insulation, which may cause a fire.
- Use the ground wire correctly
For high-power electrical appliances such as electric fans, washing machines, refrigerators, etc., use three-phase plugs and install reliable grounding wires; for lighting circuits, one wire and one ground connection method is absolutely prohibited.
- The three-level (three-hole) socket must be connected to zero protection
Many three-pole sockets (especially user-installed power strips) have not yet become true three-pole sockets, only three holes and two poles, which should be avoided.
- Wires buried in walls
In the design, the wires are indeed buried in the wall and floor stucco layer, but they generally wear sleeves. During the two renovations, some people arranged the electric wires in the walls to avoid running open wires. However, since the pipe is rarely worn (such as PVC pipe), the wall is suffering from damp or wet, and there is a possibility of leakage. To lay the wires in the dark, special attention should be paid to the problem of wires passing through the ceiling. Wires are generally not placed directly in the ceiling to avoid fire caused by short circuits. Instead, they should be placed in the ceiling after wearing casings (such as PVC pipes and steel pipes).
In addition to the need to pay attention to wire installation, we also need to pay attention when choosing household wires. When purchasing wires and cables, we must look for regular manufacturers, check the quality, and do not buy some unqualified wires because of the low price.
