Unbeatable metals for very high power.
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.
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.
Uncompromising quality from a single supplier.
We use powder metallurgy to produce our metallic composite materials. The benefit to you: perfectly harmonized material properties and an exceptionally homogeneous material composition. With modern joining technologies and fully automated production lines Plansee Powertech in Switzerland manufactures high-precision switch contact systems.
From the raw material to the finished product, we handle every production stage in-house: In this way, we guarantee top quality and the reactivity needed to meet your requirements.
- Ultra high & high voltage: WCu, CuCr
- Medium voltage: WCu, CuCr, WCAg
- Low voltage: WCAg
