11kv Cable Electrique 25 Aluminium Underground XLPE Sheath Insulated Medium Voltage Power Cable

Specifications
This cable is an 11kV medium-voltage Power Cable with a 25 sqmm Aluminum Conductor, XLPE insulation, and an outer protective sheath, suitable for underground installation. The rated voltage is 11kV, with a maximum operating temperature of 90°C and a short-circuit withstand temperature of 250°C (for up to 5 seconds). It offers excellent electrical and mechanical performance.

Features & Applications
Designed for medium-voltage power transmission, this cable is widely used in urban power grids, industrial distribution, tunnels, and underground utility corridors. The XLPE insulation provides high-temperature resistance, chemical corrosion resistance, and anti-aging properties, ensuring long-term reliability. The aluminum conductor balances conductivity and cost efficiency, making it ideal for long-distance installations.

Materials & Construction

• Conductor: EC Grade Aluminum

• Insulation: Cross-linked Polyethylene (XLPE)

• Sheath: PVC or HDPE (optional based on environmental requirements)

• Shielding: Copper tape or aluminum-polyester composite tape (optional)

Manufacturing Process
The cable is produced using triple-layer co-extrusion technology to ensure tight bonding between the conductor, insulation, and shielding layers. Rigorous quality tests, including partial discharge tests, high-voltage insulation tests, and conductor resistance tests, ensure compliance with IEC 60502, GB/T 12706, and other international/national standards.
