Product Overview

product-2357-1880

This HV power cable is manufactured with compact stranded copper or aluminum conductors and insulated with special XLPE (Cross-Linked Polyethylene) materials designed for medium and high-voltage transmission systems.

The cable structure integrates metallic shielding layers and water-blocking layers, combined with optional aluminum sheath, lead sheath, corrugated copper sheath, and other special protective structures. It offers outstanding high-voltage resistance, electric field impact resistance, waterproof performance, corrosion resistance, tensile strength, and compression resistance.

The HV power cable is mainly supplied in single-core configurations with a complete range of large cross-sectional sizes. Flame-retardant, fire-resistant, and low smoke halogen free customized models are also available according to project requirements.

 

Application Fields

 

Suitable for high-voltage and large-capacity power transmission projects, including:

  • Long-distance underground direct burial systems
  • Power transmission tunnels
  • Overhead high-voltage transmission lines
  • Large-scale power hubs and substations
  • Industrial park high-voltage power supply systems
  • Cross-regional and interprovincial backbone transmission networks

This HV power cable is designed for stable and reliable operation in demanding power infrastructure environments.
