26/35kV 1×400mm² Medium-Voltage Power Cable
- Suitable for high-capacity, high-efficiency medium-voltage power transmission systems.
- Large cross-section (400mm²) high-purity copper conductor, offering high current carrying capacity, strong transmission capability, and low loss.
- Cross-linked polyethylene (XLPE) insulation, resistant to high temperatures and aging, ensuring stable and reliable long-term operation.
- Metal shielding, water-blocking layers, and armoring can be selected according to requirements to adapt to different laying environments.
- Suitable for fixed laying applications requiring high-capacity single-core power transmission, such as substation incoming and outgoing lines, urban main power grids, large industrial projects, and new energy booster stations.
Description
26/35kV 1×400mm² Medium-Voltage Power Cable
Conductor: Copper, round, tightly stranded conductor, 400mm² cross-section
Conductor shielding (inner shielding layer): Extruded cross-linked semiconductive material (critical structural layer of medium-voltage cables)
Main insulation layer: Cross-linked polyethylene (XLPE), the core of the cable’s electrical insulation.
Insulation shielding (outer shielding layer): Extruded cross-linked semiconductive material
Metallic shielding layer: Copper tape shielding or copper wire shielding
Longitudinal water-blocking layer: Semi-conductive water-blocking tape or aluminum-plastic composite tape (configured as needed)
Strap layer: Non-hygroscopic tape
Inner sheath (isolation sleeve): Polyethylene (PE) or Polyvinyl chloride (PVC)
Armor layer: Steel wire armor provides mechanical protection and impact resistance.
Outer sheath: Polyvinyl chloride (PVC), polyethylene (PE), or halogen-free low-smoke polyolefin (WD)
Application
The YJV22 26/35kV 1×400mm² single-core medium-voltage armored cable is specifically designed for high-current transmission scenarios and is suitable for substation incoming and outgoing lines, power plant auxiliary lines, and high-voltage trunk lines in large industrial parks. Its single-core, large-section structure can withstand higher loads, and the armored design ensures mechanical safety during direct burial, conduit installation, and tunnel laying. It is particularly suitable for new energy booster stations, high-voltage motor power supply, and power distribution projects requiring single-core installation.
