Low voltage power cable
[ Product Overview ]
- Low-voltage cables are mainly used in power transmission and distribution systems with an AC rated voltage of 0.6/1kV and below. They are suitable for various installation methods such as overhead, direct burial, and pipeline laying. They have the characteristics of strong weather resistance, safety, reliability, economy and high efficiency.

- Low voltage power cable (0.6/1kV)
0.6/1kV
3Copper (Cu) or aluminum (Al)
Copper core: 1.5~630mm²; Aluminum core: 16~800mm²
PVC (polyvinyl chloride) or XLPE (cross-linked polyethylene)
0.8~2.0mm (depending on the section and standard)
PVC/PE (black weather-resistant type optional)
1.2~2.5mm
PVC：70°C；XLPE：90°C
PVC：160°C（5s）；XLPE：250°C（5s）
In terms of bending radius, the bending radius of multi-core cables needs to be ≥6 times the cable diameter, while that of single-core cables requires ≥4 times the cable diameter.
In terms of tensile strength, PVC insulated cables must reach ≥12.5MPa, and XLPE insulated cables must reach ≥10MPa
In terms of weather resistance, the cable needs to pass a 1000-hour UV aging test
There are many options for flame retardant grades, and you can choose ZC flame retardant type or ZA halogen-free and low-smoke type according to your needs.
When the cable cross-section is 25mm², the current carrying capacity of PVC insulated cable is 100A, while that of XLPE insulated cable can reach 120A.
When the cable cross-section is 50mm², the current carrying capacity of PVC insulated cable is 155A, while that of XLPE insulated cable can reach 180A.
When the cable cross-section is 120mm², the current carrying capacity of PVC insulated cable is 260A, while that of XLPE insulated cable can reach 300A.
VV/YJV cables are used for indoor power trunk lines and socket lines.
YJV22 (armored type) is suitable for factory and mine power systems.
JKLYJ cable is used for overhead lines on electric poles (span < 50m).
YJV22 (armored type) is suitable for factory and mine power systems.
Flame retardant cable (ZR series)
Fire-resistant cables (NH series)
When burying directly, sand and bricks are needed to cover the soil, and the burial depth should be >0.7m (anti-freeze treatment is required in the north).
When laying overhead, insulators must be used to fix them to avoid friction with trees.
- Keep in a dry and ventilated place, avoid direct sunlight, storage period ≤ 18 months.
- Wooden or iron shaft packaging, length is usually 100m/500m/1000m.
- Warranty period: 12 months from the date of shipment (installed and used in accordance with specifications).
