Medium voltage power cable
[ Product Overview ]
- Medium voltage cables are suitable for 6kV~35kV medium and high voltage power transmission systems, and are mainly used in urban power grids, industrial power supply, new energy power generation (wind power, photovoltaic) and other fields. They have the characteristics of high insulation strength, high temperature resistance, and anti-interference, and can meet a variety of laying methods such as direct burial, tunnels, cable trenches, and overhead.
| type | Model Examples | Main Features | Typical Applications |
|---|---|---|---|
| PVC insulation |
VV/VLV |
Stable performance, corrosion resistance, poor heat resistance, toxicity | Building interior lighting/power and factory wiring |
| PVC insulated steel tape armor |
VV22/VLV22 |
Possessing the characteristics of VV/VLV, the steel belt is resistant to pressure but poor in tension. | Underground, trench/tunnel laying |
| PVC insulated steel wire armor |
VV32/VLV32 |
Possessing VV/VLV characteristics, the steel wire has strong tensile strength | Shaft laying, bridge/tunnel engineering |
| Cross-linked polyethylene insulation |
YJV/YJLV |
High temperature resistance (90°C), high strength, stable performance, high transmission efficiency | High-rise building trunk lines, industrial high-temperature environments |
| Cross-linked polyethylene insulated steel tape armor |
YJV22/YJLV22 |
With the characteristics of YJV/YJLV, the steel belt is pressure-resistant and durable | Urban underground pipelines and park power facilities |
| Cross-linked polyethylene insulated steel wire armor |
YJV32/YJLV32 |
Possessing the characteristics of YJV/YJLV, the steel wire has strong tensile strength and good adaptability | Subsea/river laying, mine shafts |
| Low smoke halogen-free flame retardant fire resistant |
WDZN - YJV |
Low smoke, halogen-free, flame retardant, environmentally friendly, and high fire safety | Subways/airports, hospitals/data centers, emergency power systems |

10kV YJV cable is used for underground pipe corridors and substation outgoing lines.
35kV YJV22 armored cable is used for high voltage power distribution in steel mills and chemical plants.
Photovoltaic power station: PV1-F 1.8kV/3kV DC cable. Wind farm: twist-resistant wind power cable.
Submarine cable (waterproof type YJQF41). Mining high voltage cable (MYJV42, impact resistant).
- When burying directly, sand cover is required and the burial depth should be ≥0.8m (anti-freeze is required in the north).
- Bending radius ≥15D (single core)/12D (multi-core) to avoid mechanical damage.
- Avoid high temperature and humidity, and seal the cable ends to prevent moisture.
- Packaging: wooden or steel shaft, length is usually 500m (35kV), 1000m (10kV and below)
- 18 months from the date of manufacture (installed and used in accordance with specifications).
