8.7/15kV 1×500mm² Medium-Voltage Power Cable
- High-performance cable designed specifically for high-load, high-reliability power transmission scenarios.
- Extra-large cross-section conductor: Utilizes 500mm² high-purity copper conductors, providing extremely high current-carrying capacity, significantly reducing line losses, and achieving efficient power transmission.
- Advanced insulation technology: Employs cross-linked polyethylene (XLPE) insulation, featuring excellent electrical properties, thermal stability, and aging resistance, ensuring long-term reliable operation.
- Flexible structural design: Customizable metal shielding layer, water-blocking structure, and outer sheath (e.g., flame-retardant, halogen-free) to meet various engineering requirements, adapting to diverse laying environments.
Description
8.7/15kV 1×500mm² Medium-Voltage Power Cable
Conductor: Copper, round, tightly stranded conductor, 500mm² cross-section.
Conductor shield (inner shield): Extruded cross-linked semi-conductive material (standard structure for medium-voltage cables).
Main insulation layer: Cross-linked polyethylene (XLPE), cable electrical insulation. Core
Isulation shield (outer shield): Extruded cross-linked semi-conductive material
Metallic shield: Copper tape shield or copper wire shield.
Inner sheath (isolation sleeve): Halogen-free low-smoke polyolefin material
Outer sheath: Halogen-free low-smoke polyolefin (WD), environmentally friendly final protection layer.
Application
This 8.7/15kV 1×500mm² single-core medium-voltage cable uses halogen-free, low-smoke, environmentally friendly materials and is suitable for densely populated or enclosed spaces with extremely high fire safety requirements.
Main applications include:
Power trunk lines for urban subways, tunnels and integrated utility tunnels.
High-voltage power distribution systems for high-rise buildings, hospitals, airports, and data centers.
Main power supply circuit of large commercial complex.
Emergency power lines for special occasions such as nuclear power plants and ships.
Industrial and civil power distribution projects requiring strict environmental and safety standards.
The cable does not release toxic halogen acid gas when burning, and has low smoke emission, which can maximize the safety of personnel evacuation and the integrity of equipment.
