VV Cables
VV cables, known as copper core conductor PVC insulated and sheathed power cables, are very common and serve the same purpose as YJV cables in most cases, and are widely used in many areas due to their relatively low price. Often buried in the soil or laid in a room, trench, or tunnel, the insulation distance between the wires is small, without the need for towers, occupies less space, and does not occupy the ground space.
ZMS is a leading international wire and cable manufacturer, our mission is to help you solve all kinds of cable problems. For better prices on cables, please contact us.
VV Cable Product Structure
VV Cables Series
Rated voltage: 0.6/1KV, or below 35KV
Conductor: copper conductor or aluminum conductor
Insulation: PVC
Outer sheath: PVC or LSZG
Operating temperature: 90℃
Standard: The product is produced according to GB12706 “rated voltage 35KV copper core, aluminum core plastic insulated power cable” standard. Also according to the needs of users according to international standards IEC, British standards, German standards, and U.S. standards production.
The inner and outer components are the conductor, insulation layer, filling layer, (steel tape layer), and sheath layer.
The most commonly used conductor material on the market today is, of course, copper.
The insulation layer and outer sheath material are both polyvinyl chloride or PVC plastic.
The filling layer is generally some soft nylon material, to prevent direct contact between the conductors inside the cable extrusion.
The steel belt armored VV cable is a VV22 cable, the role of the steel belt armor is to resist pressure, and can be used for burial.
VV Cable Specification and Standards
VV cable executive standard is GB/T 12706.1-2008; rated voltage is generally 0.6/1KV or below 35kv.
The long-term working temperature does not exceed 70℃, and the laying temperature is not lower than 0.
The maximum allowable temperature of the cable conductor in case of a short circuit (the longest duration does not exceed 5s) is 160℃.
Not less than 10 times the outer diameter of the cable.
Generally used as a power transmission hub, often buried in the soil or laid indoors, ditches, tunnels, small insulation distance between lines, without towers, occupying less space, basically not occupying space on the surface.
VV Cable Features and Benefits
The Basic Parameters of VV Cable
1. The rated voltage of the VV cable is not high, usually lower than 0.6/1KV or 35KV.
2. The laying temperature is not lower than 0℃, and the long-term working temperature is not more than 70℃.
3.2 core.3 core.4 core.5 core.3+1.3+2.4+1.
4. The cross-sectional area starts from 1.5mm2-240mm2.
5. It is usually used as a power transmission hub. It is usually buried in the soil or laid indoors. Between trenches, tunnels, and tunnels, the insulation distance is small, there are no towers, the footprint is small and there is no ground space.
Advantages of VV Cable
1. Small footprint. Generally buried in the soil or laid indoors, small insulation distance between trenches, tunnels, and tunnels, no pylons, small footprint, and no ground space.
2. Stable transmission performance and high reliability due to less influence of climate conditions and the surrounding environment.
3. With low temperatures, superconducting power cables and other conditions are more conducive to the development of ultra-high voltage and high capacity.
4. Large distributed capacitance.
5. Less workload maintenance.
