AVR copper core PVC insulated wires for internal software installation, instrument, electronic equipment with a soft connection. RV copper core PVC insulated wires connect characteristic soft is soft, easy to bend, small diameter, light weight, easy wiring, mainly used in light of mobile appliances, instruments, household appliances, lighting, power required while using soft area. BV copper core PVC insulated wire, hard, for fixed installation, the difference between BV and RV is the core of different thickness, BV core wire cable rough, hard, internal wiring is difficult, external wiring is no problem, but also a good forming, low cost. BVR copper core PVC insulation wire, which belongs to semi hard, for fixed installation, requirements laid in the soft area.

For high temperature, high temperature wire should be used, such as AF-200 high temperature wire, temperature 200 ℃, but very expensive, should use as little as possible. Namely, also according to the actual environment temperature selection. Try to use and can meet the requirements of wire temperature at 80 ℃, 90 ℃, 105 ℃. Wire cable used in low temperature environment, bending radius is required in the minimum allowable temperature and minimum laying down installation, wire and cable insulation layer and protective layer does not crack, crack and run under the condition of low temperature for a long time without bending prestressing action or molecular structure force. For wire and cable mobile or semi mobile use, is required to withstand repeated bending with small bending radius when the mechanical stress at low temperature, and the insulating layer and the protective layer is not destroyed, the requirement of cable insulation and sheath can still maintain a certain softness and flexibility at low temperature. For anti electromagnetic interference requirements of the occasion, also should use the shielded wire.
