High Voltage Submarine Cable
Voltage: 66kV / 110kV / 132kV / 220kV / 400kV
Conductor: Copper or Aluminum | Core: Single or Three Core | Insulation: XLPE | Armor: Steel Wire or Steel Tape
Product Description:
Our High Voltage Submarine Power Cables are engineered for reliable power transmission across marine environments, including deep-sea and offshore applications. Built with XLPE insulation, water-blocking layers, and robust metallic armor, these cables offer superior mechanical protection and electrical performance for long-term use under water.
We serve clients across renewable energy, utility, and infrastructure sectors, providing cables suited for offshore wind farms, island electrification, and coastal grid interconnections.
⭐ Key Features:
High Voltage Capacity & Efficiency
Supports long-distance transmission at voltages up to 400kV, with low transmission losses and strong insulation performance.
Marine-Grade Waterproofing
Multiple layers of water-blocking tape and sheathing provide excellent resistance to seawater ingress and corrosion.
Enhanced Mechanical Strength
Steel wire or tape armoring ensures the cable can withstand external forces during laying and operation, including underwater pressure and seabed friction.
Temperature Resistant Design
XLPE insulation enables continuous operation at 90°C and short-circuit temperature up to 250°C.
Standard-Compliant Production
Manufactured to IEC 60228, IEC 60840, and IEC 62067 standards, with optional DNV, ABS, or third-party inspection as per project requirements.
⚙️ Applications:
Offshore wind farm grid connections
Power transmission between coastal cities and islands
Subsea cable networks for marine renewable energy
Offshore oil & gas platform power supply
Delivery & Support:
Transported by specialized cable-laying vessels for safe offshore deployment
