YJV22 and YJV32 10kV / 35kV medium-voltage armored cables are designed specifically for wind farms and solar photovoltaic booster stations, new energy power collection and grid-connected transmission projects.
As core medium-voltage power cables for renewable energy power plants, YJV22 and YJV32 utilize cross-linked polyethylene (XLPE) insulation and a professional armored structure, making them perfectly suited for direct burial, tunnel laying, and fixed overhead laying in new energy power plants. With stable medium-voltage transmission performance, strong mechanical protection capabilities, and excellent environmental adaptability, YJV22 and YJV32 have become the preferred cables for electrical engineers, EPC contractors, builders, and power distributors worldwide in renewable energy grid-connected projects.
Rated voltages of 10kV and 35kV, fully matching mainstream voltage levels for wind and solar thermal collectors, substation outgoing lines, and grid connection.
XLPE insulation material boasts superior performance, capable of long-term operation at 90℃, exhibiting low dielectric loss, high insulation strength, and excellent aging resistance; it operates stably under long-term full-load cyclic power generation conditions in wind and photovoltaic power plants.
It possesses strong environmental adaptability, exhibiting moisture resistance, corrosion resistance, UV resistance, and good weather resistance; suitable for various outdoor environments in new energy power plant complexes, including wilderness, mountains, deserts, and coastal areas.
- Internal power distribution in wind farms and photovoltaic substations
- Collectoring lines and medium-voltage grid-connected transmission in new energy power plants
- 10kV/35kV circuits between photovoltaic array box-type transformers and substations
- Centralized power output and medium-voltage trunk line layout for wind turbine generators
- Direct burial, cable trench, pipe gallery, and fixed overhead laying in new energy power plants
- Medium-voltage lines for rural and regional new energy grid connection
- Direct Underground Laying: The most common laying method for wind farms and photovoltaic power stations; YJV22 cables are widely used for direct burial in flat terrain, offering pressure resistance and rodent protection.
- Cable Trench and Pipe Gallery Laying: Suitable for internal substations and centralized cable layouts, facilitating daily inspection and subsequent maintenance.
- Mountainous and Hilly Terrain Laying: YJV32 steel wire armored cables are used, suitable for laying on steep slopes, with significant elevation differences, and vertical cross-sections, capable of withstanding substantial tensile forces.
- Medium-Voltage Fixed Overhead Laying: Suitable for site bridging, road crossings, and new energy trunk lines in remote areas, reducing civil engineering costs.
- Strictly adhere to medium-voltage construction standards: Follow the 10kV/35kV medium-voltage cable installation specifications; a professional construction team and standardized acceptance procedures are required to avoid potential electrical safety hazards caused by insulation damage.
- Select the appropriate model based on terrain: Use YJV22 for conventional direct burial and cable trench laying on flat ground; use YJV32 for hillsides, vertical descent, and long-distance stretching laying.
- Buried depth and foundation treatment: Maintain the standard buried depth when directly burying; lay fine sand at the bottom and top of the cable and install protective plates to prevent crushing by sharp stones and mechanical damage.
- Control the minimum bending radius: Avoid sharp bends during transportation and laying; excessive bending will damage the cross-linked polyethylene (XLPE) insulation layer and armor structure, affecting the medium-voltage insulation performance.
- Reliable grounding of armor layers: Both ends of YJV22 steel tape armor and YJV32 steel wire armor must be grounded to eliminate induced voltage and ensure the safe operation of the medium-voltage grid-connected system.
- Sheath protection during construction: Prevent dragging, scratching, and heavy rolling; damaged outer sheaths can lead to moisture intrusion, insulation aging, and shortened service life in harsh renewable energy environments.
- Heat dissipation and spacing: When multiple medium-voltage cables are laid in trenches or cable trays, reasonable spacing should be reserved to ensure heat dissipation and maintain a stable current carrying capacity under long-term power generation loads.
Wind and solar energy projects are characterized by wide site selection, complex terrain, long transmission distances, and continuous full-load operation.
10kV/35kV medium-voltage grid-connected cables must balance insulation reliability, mechanical protection, and terrain adaptability. YJV22 and YJV32 cables meet the core requirements of new energy power plants: they offer pressure resistance and rodent protection when directly buried in flat land, and high tensile strength in mountainous and undulating terrain.
The appropriate selection of YJV22 and YJV32 cables can optimize project budgets, reduce line failure rates, decrease operation and maintenance costs, and fully meet international new energy EPC bidding and grid connection standards.
YJV22 and YJV32 10kV/35kV medium-voltage armored cables are indispensable core products for wind farms, photovoltaic booster stations, and new energy grid-connected power transmission. With reliable medium-voltage insulation performance, graded armor protection, excellent mechanical properties, and wide environmental adaptability, they are perfectly suited for various laying methods in new energy power plants, including direct burial, cable trench, hillside, and overhead installations.
By selecting the appropriate cable type based on terrain conditions and following standardized installation specifications, engineers and power contractors can ensure the long-term safe, stable, and low-loss operation of renewable energy collection and grid connection systems.
