What Are The Safety Risks of Using Shoddy Home Decoration Wire And Cable

What are the safety risks of using shoddy home decoration wire and cable:

Home decoration wire and cable as the main role of power transportation and signal transmission, China has been strictly checking the quality of home decoration wire and cable, and some poor manufacturers to produce fake and shoddy wire and cable in order to seek personal gains. The key problems of fake and shoddy wire and cable include specifications, resistors, insulation sheath and other aspects. Here to take you in-depth analysis of this shoddy goods will cause what hidden dangers.

1. After the short circuit fault (short circuit fault) of home decoration wire and cable, the common fault is disconnected by relay protection, causing the overtemperature of wire and cable and the fire of the cable sheath.

2. The compressive strength and elongation rate of the insulation sheath before aging are not up to standard, which immediately greatly shortens the service life of wire and cable. In addition, in the engineering or long-term plug-in and continuous high temperature environment, it is easy to cause the rupture of the insulation, leading to the exposure of the electric conductor, and produce the risk of electric shock accident type short circuit fault.

3. If the conductor resistance does not meet the requirements, when the conductor resistance exceeds the standard, the current damage on the lifting route will be caused to aggravate the heating of the wire and cable. The main reason for the conductor resistance is that in order to control the cost, the company will reduce the copper, which accounts for 80% of the material cost, or reduce the cross-sectional area of the conductor, or use too many impurities to regenerate copper, resulting in the conductor resistance of the wire and cable is seriously over the standard.

4. The home decoration wire and cable cable sheath will slowly age in normal operation, the wire is often loaded or overvoltage during the service period, plus the cable sheath is thin and thick, the assembly is unreasonable (such as the cable bending radius is too small, the diameter of the wire maintenance pipe is too small), which may lead to safety accidents.

5, the section size does not meet the requirements of wire and cable, the key of the section size is the thickness of the wire cover insulation layer, when the cable cover and insulation layer does not meet the requirements, the electrical strength of wire and cable will be significantly reduced, resulting in the reduction of the service life of wire and cable. In more serious cases, the wire and cable will fail, the insulation layer (sheath) layer can not have the normal maintenance effect, resulting in the short circuit fault of electrical equipment and fire accidents.
