Wire and cable industry is an important supporting industry in China's economic construction. It is widely used in various fields of national economy. It occupies 1/4 industry in China's electrical industry. It ranks only second to auto industry in machinery industry. Among them, the use of the interior decoration of the wire is mainly rated voltage 450/750V or below polyvinyl chloride insulated cable, also known as cotton covered wire.
 
 
PVC insulated cable wire products are divided into fixed wiring non sheathed cable, fixed wiring with sheathed cable, light non sheathed flexible cable, general purpose sheathed cable, installation wire and shielded wire, special purpose sheathed flexible cable, PVC insulation flame retardant / fire resistant cable and other products.
 
PVC insulated flexible cable (wire) is applied to the rated voltage 450/750V or below control, signal, protection and measurement system of the connection.
 
 
Usage characteristics:
 
1, power frequency rated voltage Uo/U is 450/750V or 0.6/1KV.
 
2, the cable conductor allow the maximum operating temperature is 70℃.
3, cable laying, the environment temperature should not be less than 0℃, if the environment temperature is below 0℃, the cables should be warm.
 
4, the cable permissible bending radius are following: non armoured cable, not less than 6 times of cable diameter;
Armoured or copper tape shielded cable, not less than 12 times of cable diameter; shielded cable, not less than 6 times of the cable diameter.
 
Wire quality assessment is mainly carried out by professional inspection agencies, the main technical indicators in the report are the following:
 
1. conductor DC resistance. Directly reflect the load carrying capacity of the wire, which is usually said to be able to bring much load. This indicator is related to the conductor material and the conductor cross-sectional area (wire specification).
 
2. finished product withstand voltage test. The main assessment of the external insulation of the wire is leakage. The index is related to the material and the manufacturing process of the insulation.
 
3. insulation (sheath) thickness and mechanical properties, etc.. The main assessment of the life and use of the environment. Insulation thickness is too thin or partial core, easy to install or use in the thin location of the damage, the formation of leakage. The use of the use of poor quality insulation material of short life.
