AVR copper core PVC insulated flexible wire for installation, used for internal flexible wiring of instrumentation, electronic equipment, etc. RV copper core PVC insulated connection soft wire is characterized by softness, flexibility, small outer diameter, light weight, and easy wiring. It is mainly used for medium and light mobile electrical appliances, instrumentation, household appliances, power lighting, etc., which require softness when used occasion. BV copper core PVC insulated wire, which is relatively hard, is used for fixed laying. The difference between BV and RV lies in the thickness of the core wire. The BV core wire is thick and the cable is hard. The wiring inside the machine is difficult, and the wiring outside the machine is no problem. And it is easy to shape and low cost. BVR copper core PVC insulated flexible wire is semi-hard. When used for fixed laying, it is required to be laid in a soft place.

For high-temperature occasions, high-temperature wires should be used, such as AF-200 high-temperature wires, which can withstand temperature of 200℃, but they are very expensive and should be used as little as possible. Even if it is used, it should be selected according to the actual ambient temperature. Try to use wires that can meet the requirements with temperature resistance of 80°C, 90°C, and 105°C. Wires and cables used in low temperature environments require that the insulation and sheath layers of the wires and cables are not cracked when they are installed under the allowable lower ambient temperature and smaller laying bending radius, and are not affected by long-term operation under low temperature conditions. Cracking due to bending prestress or molecular structural force. For mobile or semi-mobile wires and cables, it is required to be able to withstand the mechanical stress of multiple bends with a smaller bending radius at low temperatures, and the insulation layer and sheath layer are not damaged, that is, the insulation and protection of the cable are required. The sleeve can maintain a certain degree of softness and elasticity under low temperature conditions. For occasions with anti-electromagnetic interference requirements, shielded wires should also be used.
