The Power Transmission and Distribution (T/D) business unit develops durable and extremely temperature-resistant switch contact systems. Our customers use these systems to control voltages of up to 1 200 kilovolts and currents of up to 50 kiloamps. Arcing generates temperatures of up to 20 000 °C. Where conventional metals would fail, tungsten-copper (WCu), copper-chromium (CuCr) and tungsten carbide-silver (WCAg) keep a cool head.

Switching contacts made of tungsten-copper are relied on to interrupt and connect the electrical circuit even at high voltages.

Indestructible: With their high wear resistance and optimum arc erosion properties, our arcing contacts can reach a service life of over 40 years.

Ready for installation: The contacts alone are not enough - we assemble and connect all the necessary individual parts of the moveable and fixed switch contact and supply you with the complete contact system ready for installation.
