Highly-Efficient Power Feedthroughs for Vacuum Systems
|
Power is the description for electrical feedthroughs used for the transmission of high voltages and/or high current into vacuum systems. Power feedthrough options include many variations of design which offer a broad range of voltage and current. High purity alumina ceramic insulators provide electrical isolation and various conductor materials offer specific current capacities. MPF offers several mounting options for power feedthroughs: Weldable, Quick Flange (QF), Conflat Flange (CF), and Baseplate (BP). Baseplate versions of power feedthroughs are commonly used in vacuum furnaces and vacuum coating applications. Many designs are also configured for NPT style adapters. Custom adapters, plates and flange configurations are available by request. |
