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.

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).
