Wintrack pylon successfully tested

In December the new Wintrack high-voltage pylon passed its first major test with flying colours. The pylon received a massive surge of current of 50 kA for half a second, peaking at 125 kA. The new pylon consists of two slender poles from which electric wires are suspended. The ingenuous suspension method creates a much smaller magnetic field, allowing the government’s extremely strict requirements in this regard to be met. With the current type of 380 kV pylon and line, construction restrictions would apply to a strip of land of approximately 300 metres wide around the high-voltage line, according to the guideline. The Wintrack pylon reduces this so-called ‘magnetic field zone’ to less than 100 metres.
