yjv cable insulation material
YJV cable is a copper-core polyvinyl chloride insulated power cable commonly used in electrical power transmission and distribution systems in the domestic, industrial and commercial sectors. yjv cable is usually insulated with polyvinyl chloride (PVC).
PVC is a commonly used insulation material with good insulation, heat and chemical resistance properties, as well as high mechanical strength and abrasion resistance. the advantages of PVC insulation materials include low manufacturing cost, easy processing, and stable insulation performance. Therefore, PVC insulation materials are widely used in power cables, communication cables, control cables and other fields.
Yjv wire and cable specifications are diverse, for example, manufacturers can make it into combustion-assisted yjv wire and cable, fire-resistant yjv wire and cable, etc. according to user needs. If divided according to the core, can also be divided into single-core, multi-core products. Multi-core yjv wire and cable is more common with 3 cores, 4 cores, 5 cores and so on. If divided according to the voltage, can be divided into extra high voltage, high voltage, medium voltage, against voltage wire and cable.
YJV cable insulation materials need to comply with the national standard GB/T 12706.1-2008 “rated voltage 1kV (Um = 1.2kV) to 35kV (Um = 40.5kV) cross-linked polyethylene insulated power cable”, including the physical and chemical properties of insulation materials, electrical properties, mechanical properties and other aspects of the requirements. When selecting and using YJV cables, it is necessary to determine the appropriate cable specifications and models according to the specific application requirements and standard regulations, and to install and use them in accordance with the standard requirements to ensure the quality and safety of the cables.
