Xi'an Wire and Cable VV Power Cable
Introduction to VV Power Cable
1. Name: Polyvinyl Chloride Insulated Polyvinyl Chloride Sheathed Power Cable Voltage: 0.6/1kV Executed Standard: GB/T 12706.1-2008 Rated Voltage 1kV (Um=1.2kV) to 35kV (Um=40.5kV) Extruded Insulation Power Cable and Accessories Part 1: Rated Voltage 1kV (Um=1.2kV) and 3kV (Um=3.6kV) Cable (Current) Advantages: 1. Occupies less land. Generally buried in soil or laid indoors, in trenches, or tunnels, with small insulation distances between conductors, requiring no poles, occupying minimal surface space.
2. High reliability. Less affected by climatic conditions and surrounding environments, stable transmission performance, and high reliability.
3. More favorable conditions for development towards ultra-high voltage and large capacity, such as low-temperature superconducting power cables.
4. Relatively large distributed capacitance.
5. Less maintenance workload.
6. Low possibility of electric shock.
VV Power Cable Models
1. The types of insulation, conductor material, inner sheath material, and structural characteristics are represented by uppercase letters in pinyin. For example, Z represents paper (zhi); L represents aluminum (lv); Q represents lead (qian); F represents phase separation (fen); ZR represents flame retardant (zuran); NH represents fire-resistant (naihuo).
2. The outer sheath composition is represented by a two-digit number. No number indicates no armored layer or outer sheath. The first digit indicates armor, while the second digit indicates the outer sheath, such as coarse steel wire armoring with fiber outer sheath represented as 41.
3. The cable model is generally arranged in the order of: insulation material; conductor material; inner sheath; outer sheath.
4. Cable products are represented by model, rated voltage, and specifications. This is done by adding the rated voltage, number of cores, and nominal cross-sectional area after the model.
Usage Characteristics of VV Power Cable
1. The long-term allowable working temperature of the cable conductor exceeds 70℃.
2. During a short circuit (lasting no more than 5 seconds), the maximum temperature of the cable conductor does not exceed 165℃.
3. The cable is not restricted by laying drop, and the ambient temperature during cable laying should not be less than 0℃.
4. Good chemical stability, resistant to acids, bases, salts, oils, and organic solvents, with flame retardant properties.
5. Lightweight with good bending performance, simple and convenient installation and maintenance.
