Tungsten copper high voltage electrical contacts / Arc Tolerant Contacts
Chinatungsten Online is the forerunner in manufacturing high voltage contacts and arc tolerant electrical contact materials. Tungsten copper electrical contacts materials are hard and durable, with good conductivity and particularly resistant to the erosive damage of contacting arcing.
Higher voltage applications bring a diverse set of challenges in design and wear of electrical contacts. Some of these high voltage contacts are operated in oil, others in air, others in a vacuum and still others in varying gases to deal with the unique requirements of high voltage applications. Some of the problems encountered will be high wear, arcing and sticking (or welding). In this section you'll find a large number of China Tungsten Online manufactured materials perfectly suited to meet these challenges.
Our contacts with Cu/W insert in the different compositions are applied in gas switches.
The devices in which our contacts are used are for:
- HV primary distribution
The nominal operating voltages are from 70 to 220K
