AC Submarine Power Cables

XLPE insulated fibre-optic composite AC submarine cable with voltage 500 kV or below

Applicable to offshore wind power, offshore photovoltaic, island power interconnection and other marine power transmission fields, voltage level 500 kV and below, conductor cross-section 3000mm2 and below, transmission capacity 1.5 GW and below, 500 kV single-core, three-core crosslinked polyethylene-insulated AC submarine cables, and other products have passed the national new product identification, and the comprehensive technical performance has reached the international leading level.

  • 3-core AC submarine cable: Integrates three-phase conductors into a single compact structure, suitable for medium-to-short-distance power transmission.
  • 1-core AC submarine cable: Designed for long-distance, high-voltage power transmission with greater flexibility.
  • High Voltage Ratings:

Offers multiple voltage classes including 35 kV, 66 kV, 110 kV, 220 kV, 330 kV and 50 0kV, with 220 kV and above products widely applied in large-scale offshore wind farm projects.

  • Large Conductor Cross-Section:

Conductor cross-section up to 3000mm² enables high-capacity power transmission while reducing line losses.

  • Multi-Layer Shielding and Waterproof Design:

Utilizes lead alloy or aluminum-plastic composite sheathing combined with water-blocking materials to ensure long-term waterproofing and corrosion resistance.

  • High Mechanical Strength:

Armored with galvanized steel wires or non-magnetic stainless steel wires, providing excellent tensile, compressive and impact resistance to withstand harsh marine environments.

  • Optimized Dynamic Performance:

Specially designed dynamic cables for offshore wind applications feature superior bending resistance and fatigue endurance to accommodate turbine movements and wave impacts.

  • Offshore wind farm cluster connections
  • Cross-sea power transmission
  • Power supply for offshore oil& gas platforms
