Cables de Energía Submarinos de CC

XLPE insulated fibre optic composite DC submarine cable with voltage of ±525 kV or below

Applicable to offshore wind power, island power interconnection and other marine power transmission field, voltage level ±525 kV and below, conductor cross-section 3000mm² y menos, capacidad de transmisión de 2 GW o menos.

ZTT’s HVDC submarine cables deliver up to ±525 kV and 2 GW transmission capacity, featuring XLPE insulation and integrated optical fibers for real-time monitoring. Designed for harsh marine environments, they enable efficient, long-distance power transfer across offshore wind farms, inter-island grids, and international subsea interconnects.

Deep-Water Reliability:

Triple-layer anti-hydrogen barrier (lead alloy sheath + HDPE jacket + semiconductor shield) prevents H₂ penetration at depths >2000m.

Ultra-Low Losses:

Optimized conductor stranding reduces joule losses by 15% vs. industry standard (±525 kV/3000mm²).

Smart Monitoring:

Integrated DTS/DAS fiber sensors enable ±0.2°C temperature accuracy and fault localization within 10m.

Offshore Wind Power: Inter-array grid connections (±320 kV) and export cables (±525 kV) for multi-GW wind farms.
Inter-Island Interconnectors:Long-distance HVDC links.
Oil & Gas Platform Electrification: High-reliability DC supply for offshore platforms.
International Subsea Grids:Cross-border submarine interconnections (up to ±525 kV).
