Frequently asked questions
What are renewable energy cables?
Renewable energy cables are specialist cables designed for use within renewable power generation systems, including solar, wind, hydro, tidal, geothermal and bioenergy applications. They’re manufactured to withstand demanding environmental conditions while delivering reliable electrical performance.
What cables are used in renewable energy projects?
The type of cable depends on the application. Renewable energy projects commonly use power cables, control cables, instrumentation cables, solar cables and specialist offshore cable constructions. The correct cable specification depends on factors including voltage, environmental exposure and installation method.
Are solar cables different from standard electrical cables?
Yes. Solar cables are specifically designed for photovoltaic (PV) systems and are manufactured to withstand prolonged UV exposure, temperature fluctuations and other outdoor operating conditions. They’re typically manufactured with materials like cross-linked polyethylene or thermoplastics to allow for longer life and to perform safely in more extreme environments. Solar cables are also available in constructions designed to meet relevant photovoltaic cable standards, such as UL 4703, where applicable.
What cables are used in wind turbines?
Wind turbine cable requirements vary depending on whether the installation is onshore or offshore. Offshore applications often require highly durable cable constructions capable of withstanding harsh marine environments, while onshore installations may use LSZH-insulated and sheathed cable constructions to provide additional fire safety. Materials including polyolefin (PO) and ethylene vinyl acetate (EVA) are commonly used depending on the application.
Can renewable energy cables be customised?
Yes. At Custom Designed Cables, we specialise in designing and manufacturing bespoke cables for renewable energy projects. We can tailor conductor configurations, insulation systems, screening, jacket materials and overall cable construction to meet your exact application requirements.
