Cables are materials used for power, electrical and related transmission purposes. Usually the products with fewer cores, small product diameter and simple structure are called wires, those without insulation are called bare wires, and the others are called cables. The following cable brand matters needing attention?
Cable brand products According to the provisions of the national standard, the surface of the wire and cable should have the manufacturer's name, product model and rated voltage continuous marks. This is conducive to the use of wires in the process of problems can be found in time to the manufacturer, we must pay attention to this point in the purchase of wires. At the same time, attention should be paid to whether the manufacturer's name, product model and rated voltage marked on the certificate are consistent with the printed marks on the surface of the wire to prevent counterfeit products. When we buy wire, we should pay attention to whether the appearance of wire is smooth and flat, insulation and sheath layer is not damaged, whether the logo is clear, whether the surface of the wire is greasy. Cable brand also from the cross section of the wire to see, the entire circumference of the wire insulation or sheath thickness should be average, not biased core, insulation or sheath should have a certain thickness, and the thickness of the sheath should not be the same as the thickness of the entire insulation core. Diameter of conductor wire. When we buy cable brands, we should pay attention to whether the diameter of the wire is consistent with the parameters marked on the certificate. If the cross section of the conductor is too small, it is easy to heat the conductor and lead to short circuit. It is recommended that the household lighting line wire should be 1.5mm2 or above. Power household appliances such as air conditioners, refrigerators, and microwave ovens should be wired with a specification of 2.5mm2 or higher to avoid unnecessary risks.
Cable brands should be standardized when using wiring and installation. The fixed line uses bv single conductor through the pipeline. Do not damage the wire when wiring. Do not connect in the middle of the line or connect in the middle; Do not touch the wire when it is connected to the electrical box (box); Single-wire power supply is used for household appliances with large power consumption. A proper distance should be kept between weak and strong current. Select an appropriate environment during installation. The external environment and heat source of the cable can also lead to excessive cable temperature, insulation breakdown, and even explosion and fire. During the installation process, the connection color of the cable brand should not be connected incorrectly. The link ids on both ends must be identical. Must pay attention to waterproof. Do not use water to clean any electrical equipment. Do not use cables with mechanical damage. Do not walk on cables with cable brands. Do not store in places containing acid, alkali and high corrosion (except in special circumstances). During the disassembly process, do not drag the cable too hard, which can easily cause cable damage and external links to fall off. When connecting, take care to check the insulation between the cable and the motor, but do not test the insulation after connecting the cable to the inverter module.
