132kv Single Core & Three Core Submarine cable Application
220kV submarine power cables are high-voltage, insulated transmission cables designed for subsea power transmission over long distances. The use of lead sheath provides excellent water ingress protection, chemical resistance, and long-term reliability, especially in harsh subsea environments.Single Core 220kV Submarine Cable with Lead Sheath Typical Applications:
High-capacity offshore wind farm export cables
Grid interconnection across seas or large rivers
Long-distance, high-load power transmission
Three Core 220kV Submarine Cable with Individual Lead Sheath Typical Applications:
Island power supply
Medium-to-long-distance submarine links where a compact design is needed
Subsea cables with long design life and high environmental resistance
220kv Single Core & Three Core Submarine cable Standards
IEC 60502-2, IEC 62067, CIGRÉ TB 623 / TB 490, IEEE Std 1120
