Plansee Powertech is a leading producer of arcing contact systems for the power transmission and distribution sector. Located at the heart of the arcing chamber, contact materials have to withstand temperatures up to 20,000 °C.
Thanks to their unique physical properties, its contact materials tungsten-copper (WCu) and copper-chromium (CuCr) have set new standards for the industry in the field of ultra-high, high-, medium- and low-voltage applications. For the near-net shape production of copper-chromium-contacts Plansee Powertech has developed a special production process.
Tungsten carbide-silver (WCAg) is another impressive material due to its combination of particularly high wear resistance, thermal conductivity and high resistance to arc erosion.
