Douglas Electrical Components' StudSeal hermetic feedthroughs for high-current application
Douglas Electrical Components Inc. introduces its StudSeal hermetic feedthrough product family, which offers a selection of solid copper, heavy-current conductors sealed in a variety of standard housing styles and materials. The stud connectors from this line are used in vacuum or pressure applications where high current or high voltages penetrate a barrier. The customized passthroughs offer easy specification and mounting, and are pretested and shipped to the customer directly. StudSeal feedthroughs can seal high-pressure or high-vacuum environments, and are compatible with a variety of liquids and gases. These hermetically sealed studs are primarily used for the transfer of power into and out of a sealed environment at operational loads up to 1000 amps and 15kV.
Offering a variety of configurations, StudSeals typically consist of a threaded rod on both sides of the hermetic seal. Other standard and custom solutions are also available, such as crimp fittings, terminal-to-wire solutions occurring inside of the epoxy and compression fittings where the wire compresses against the stud itself via a threaded set screw. DECo also offers multi-stud configurations that not only reduce installation time and potential leak paths, but also reduce the burden on purchasing departments. These multi-stud designs seal terminals directly into a bulkhead plate for transfer of three-phase or for six-phase power. While similar industry feedthroughs typically only offer threaded metal housing solutions, DECo can provide epoxy-based radial o-ring solutions that don’t require threading, resulting in increased value through faster installation at a lower cost.
