AVR copper core polyvinyl chloride insulated installation of flexible wires, used for internal soft wiring of instruments, electronic equipment, etc.RV copper core polyvinyl chloride insulated connection flexible wire is characterized by softness, easy to bend, 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. When softness is required. Occasions.BV copper-core polyvinyl chloride insulated wire is relatively hard and is used for fixed laying. The difference between BV and RV is that the thickness of the core wire is different. The BV core wire is thick and the cable is hard. The wiring inside the machine is more difficult, and the wiring outside the machine is no problem, and it is easy to form and the cost is low.BVR copper core polyvinyl chloride insulated flexible wire is semi-hard. When it is used for fixed laying, it is required to be laid in a soft place.
For high-temperature occasions, high-temperature wires, such as AF-200 high-temperature wires, should be used, with a temperature resistance of 200℃, but they are very expensive and should be used as little as possible.Even if it is used, it must be selected according to the actual ambient temperature.Try to use wires with a temperature resistance of 80℃, 90℃, and 105℃ that can meet the requirements.For wires and cables used in low-temperature environments, it is required that when installed at the allowable lower ambient temperature and the smaller bending radius of the laying, the insulating layer and sheath layer of the wires and cables will not crack, and they will not be cracked by bending prestress or molecular structural forces during long-term operation under low temperature conditions.For mobile or semi-mobile wires and cables, it is required to be able to withstand the mechanical stress when bending multiple times with a smaller bending radius at low temperatures, and the insulating layer and sheath layer are not destroyed, that is, the insulation and sheath of the cable are required to maintain a certain degree of softness and elasticity under low temperature conditions.For occasions where anti-electromagnetic interference requirements are required, shielded wires should also be used.
