230kV/250kV/320kV SUBMARINE CABLE

Characteristics

We manufacture 1-core armoured array cables, with copper or aluminum conductors and cross-sections up to 2000 mm². For the shielding, copper wires are used, or coating with layers of copper, aluminum or lead.

The continuous increase of offshore wind farm sizes and wind turbine output power, has given rise to a clear trend towards higher voltage array cabling.

We currently offer 245 kV inter array cables and consider the development of higher voltages.:

1. It doubles the power that can be transported over one cable, thus reducing the total length of cable required.

2. Fewer overall cables are required, thus reducing the amount of accessories and equipment required.

3.Single-mode or multi-mode optical fiber (G 652D & G 655): 1~144 cores
