It takes a special kind of cable to control the extreme electrical fields and huge energy discharges when lightning strikes
Lightning strikes constitute a major risk for wind turbines. So extra-special high-voltage cables are needed to protect these hi-tech marvels of engineering from the immense electrical fields that can cause sparks to fly through the air across distances of up to several kilometres. Added to this are the huge current surges and specific energies released at the time of the strike itself.
Drawing on our peerless expertise in lightning protection, Polytech has specially developed a range of high-voltage cables for LPS solutions in nacelles and wind turbine blades. These cables are distinguished by levels of flexibility and compatibility which, in the context of both electrical properties and mechanical adhesion, place them firmly in a class of their own.
Another feature of Polytech high-voltage cables is the fact that they are subjected to stringent tests in the same demanding category as cables used in the aeronautical industry. Combined with our inline SCADA quality supervision system, this ensures that each and every cable provides maximum performance and protection throughout the service life of the wind turbine in question.
