Power transmission and distribution
The Power Transmission and Distribution business unit develops durable and extremely temperature-resistant switch contact systems. Our customers use these systems to control voltages of up to 1200 kilovolts and currents of up to 50 kiloamps. Arcing generates temperatures of up to 20 000 °C. Conventional metals would fail for this application, copper tungsten, copper chromium and tungsten carbide-silver keep cool. Our arcing contacts are highly wear resistance and optimum arc erosion properties.
