YJV cable, or cross-linked polyethylene insulated and polyvinyl chloride sheathed power cable, is a low- and medium-voltage cable used for power transmission. The following are the main features and structure of YJV cable:
1. Insulation Material: The insulation of YJV cable is made of cross-linked polyethylene, which has excellent electrical insulation properties and effectively isolates the current within the wire, ensuring safe and reliable power transmission.
2. Conductor: The conductor of YJV cable is typically made of copper or aluminum, which has excellent conductivity and is suitable for power transmission. These conductors are typically multi-core to meet different power requirements.
3. Sheath: The outer layer of YJV cable is made of polyvinyl chloride (PVC) sheath, which provides mechanical protection and corrosion resistance, extending the cable's service life.
4. Applications: YJV cable is widely used in construction, industry, power stations, and other applications for power transmission and distribution.
YJV steel-wire armored power cable is a variant of YJV cable. Its most notable difference is the presence of a steel-wire armor layer, which provides additional mechanical protection and shielding. Common types include YJLV22 steel wire armored cables and YJV32 steel wire armored cables. The following is the structure and features of YJV steel wire armored power cables:
1. Steel Wire Armor: The core of the YJV steel wire armored power cable is a layer of steel wire armor, which provides the cable with extremely high tensile strength and folding resistance. It is particularly suitable for use in buried, underground, or environments subject to mechanical stress.
2. Insulation and Conductor: The insulation and conductor components of the YJV steel wire armored power cable are similar to those of ordinary YJV cables, still using cross-linked polyethylene insulation and copper or aluminum conductors.
3. Jacket: Like the YJV cable, the YJV steel wire armored power cable also uses a PVC jacket for corrosion and mechanical protection.
4. Applications: The YJV steel wire armored power cable is suitable for applications requiring additional protection, such as underground power transmission, submarine cables, outdoor cables, and environments requiring resistance to mechanical stress.
