Cable Solutions for Offshore Wind Farms

Project Background

A coastal area plans to build offshore wind farms on a large scale to meet the growing demand for clean energy. However, the harsh offshore environment, high salt spray, strong winds and other factors have placed extremely high demands on the performance of cables.

Project Requirements

• Super corrosion resistance: Submarine cables need to be immersed in seawater for a long time, so they must have strong seawater corrosion resistance to extend their service life.

• High tensile strength: Submarine cables need to withstand the huge pressure of seawater and the impact of ocean currents to ensure that the cables remain stable in the submarine environment.

• Excellent flexibility: Submarine cables need to adapt to the complex terrain of the seabed and have good bending properties to facilitate installation and laying.

• Excellent electrical performance: Cables need to have low loss, high insulation strength and other characteristics to ensure efficient transmission of electrical energy and stable operation of the system.

• Long life: The replacement cost of submarine cables is extremely high, so they need to have a long service life to reduce maintenance costs.

Shenxing Solution

Shenxing customized a high-performance submarine power cable solution for this project, as follows:

Cable structure optimization:

• Conductor: High-purity annealed copper stranded wire is used, which has the characteristics of low resistance and low loss, and improves the efficiency of power transmission.

• Insulation layer: Cross-linked polyethylene (XLPE) is used as the insulation material, which has excellent electrical properties and heat resistance.

• Shielding layer: It is woven with copper tape or copper wire to effectively shield external electromagnetic interference and improve the quality of signal transmission.

• Sheath layer: Polymer composite materials (such as TPU) are used as sheath materials, and antioxidants and anti-ultraviolet additives are added. It has strong seawater corrosion resistance, weather resistance and anti-aging performance.

• Special filling materials: High-performance filling materials are used to effectively fill the internal gaps of the cable and improve the compressive strength and waterproof performance of the cable.

Technical highlights

• Polymer composite sheath: Adopts new polymer composite materials, which have stronger seawater corrosion resistance, tensile strength and flexibility, significantly extending the service life of the cable.

• Special filling materials: Adopt high-performance filling materials to effectively fill the internal gaps of the cable, improve the compressive strength and waterproof performance of the cable.

• Professional design and manufacturing process: Shenxing has advanced cable design and manufacturing technology, and can customize the production of submarine power cables of various specifications according to customer needs.

Customer Value

• Extend the service life of cables: High-performance materials and advanced manufacturing processes significantly extend the service life of cables and reduce maintenance costs.

• Improve system reliability: Excellent electrical and mechanical properties ensure long-term stable operation of cables in harsh submarine environments.

• Reduce operation and maintenance costs: Reduce the number of cable failures and repairs, and reduce operation and maintenance costs.

• Improve power generation efficiency: Low-loss cable design improves power transmission efficiency and increases power generation revenue.
