Wind has been one of the fastest-growing power sources worldwide for the last twenty years, with an annual average growth rate exceeding 30% and with one newspaper recently predicting that by 2050, offshore wind could provide all our energy needs, PMA looks set to be crucial in the production line assembly.
All components used in the manufacture of off-shore turbines must be easily installed, survive exposure to extreme conditions and be utterly resistant to decay and abrasion from sea water. Durability is another important factor: due to the amount of wind power at sea, he components of off-shore wind turbines are constantly in motion, tension is continually applied to the cables and corroded areas can also cause difficulties.
To ensure each turbine is built to last, each component must be coated with sufficient protection to ensure it continues to work. And while metal may be the first thought, nylon cable protection has presented an unlikely solution.
Polyamide-based products exhibit very good resistance to seawater, fluctuations in temperatures, extreme weather and large forces – and unlike metal, the material doesn’t rust or corrode – it remains flexible and hard-wearing. This is confirmed by both the suppliers of raw materials, based upon chemical composition, and by long term application experience of polyamide products on off-shore platforms and on-board ships worldwide.
PMA’s Tony Hollands says: “Our polyamide products have been subjected to extensive testing to show their suitability for various application areas. As well as the various accelerated test procedures, such as Xenon Arc UV radiation testing, we’ve also had a long-term weathering test running at our manufacturing facilities for over twenty-five years.
The material’s qualities have also rendered it suitable for photovoltaic and geothermal installations, solar heating, power generation, hydroelectric power stations and energy storage facilities in the form of potential energy or water or air pressure, showing that nylon is fast becoming the preferred choice of cable protection for the power industry.
