Pressure and Vacuum Feedthroughs

Series EF - High voltage / current electrode

The integral electrode mounted in these feedthroughs enables specifiers to provide high-voltage, high-current supplies in process enclosures, autoclaves, vacuum furnaces and reactor vessels to power heaters, electric motors and other devices needing high power supply.

Feedthroughs are available with three sizes of copper electrodes rated 40A, 100A & 200A at 2kV maximum. Stainless steel conductors, that have a lower current rating than copper electrodes, can be specified instead of copper. These are often used when temperatures exceed 380ºC. Nickel conductors may also be specified to special order.

Feedthroughs with copper electrodes have brass nuts and washers. Stainless steel nuts and washers are fitted to stainless steel and nickel electrodes.

Series EF sealed electrode assemblies are supplied pre-torqued for immediate installation. Integral insulators are Alumina.
