Cables with Improved Water Resistance for Installation in Offshore PV System

July 26, 2024

Offshore Water Resistance cables, also known as Marine solar cables or offshore solar cables, are specifically designed for the installation and operation of photovoltaic (PV) systems in offshore environments. Compared with photovoltaic systems on land, the cables of offshore photovoltaic systems need to have higher weather resistance and corrosion resistance to adapt to the complex Marine environment.

Main features:

1. Seawater corrosion resistance: Due to direct exposure to Marine water, offshore photovoltaic cables usually use special materials and coatings, such as polyvinyl chloride (PVC) outer layer or higher grade fluorine plastic outer layer, to resist salt, tide and biological erosion.

2. Anti-ultraviolet: The intensity of sunlight and ultraviolet radiation on the sea is higher than that on land, so the offshore Photovoltaic Cable needs to have good anti-ultraviolet performance to extend its service life.

3. Mechanical strength: Considering the wind and wave impact of the offshore environment and potential physical damage, offshore photovoltaic cables need to have high mechanical strength and toughness to ensure stable operation under extreme weather conditions.

4. Electrical performance: Maintain good electrical insulation and conductivity, even in wet or salt water environment to ensure power transmission efficiency and safety.

5. Ease of installation: For offshore installation, these cables may be designed with specific joints and connectors to facilitate laying and maintenance in complex water conditions.

6. Long-term stability: Considering the particularity of the offshore environment, offshore photovoltaic cables need to be rigorously tested to ensure stable performance over a decades-long service cycle.

Application scenario:

Offshore wind farms: photovoltaic systems connected to the grid with wind turbines can take advantage of the complementarity of solar and wind energy to improve the stability and efficiency of energy production.

Island Power Systems: Provide clean energy solutions for islands far from the mainland or within the reach of the grid.

Offshore platforms: Provide power supply for offshore oil and gas drilling platforms, offshore research stations, etc.

The development of offshore photovoltaic cables is part of the technological innovation in the field of renewable energy, which aims to promote the application of clean energy worldwide, reduce dependence on fossil fuels, and promote environmental protection. As technology advances and costs decrease, offshore photovoltaic systems are expected to become an important part of the future green energy infrastructure.
