Douglas Electrical Components Introduces StudSeal(TM) Hermetic Feedthroughs for High-Current Applications

Customized connector seals allow for easy specification and mounting (RANDOLPH, N.J.: May 21, 2009) Douglas Electrical Components, Inc. (DECo) (www.douglaselectrical.com) introduces its StudSeal(TM) hermetic feedthrough product family, which offers a selection of solid copper, heavy-current conductors sealed in a wide 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 large variety of liquids and gases including the latest refrigerants, oils, heat transfer fluids and jet fuels. These hermetically sealed studs are primarily used for the transfer of power into and out of a sealed environment at operational loads up to 1000amps 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. "It is vital to your project to specify the proper feedthrough, since mistakes can derail completion and potentially lead to critical occurrences," says Ed Douglas, president of DECo. "Power transfer solutions configured in-house can sometimes cause serious malfunctions, such as venting, which result in a major failure point. Our technical experts add value by designing around these issues to prevent potentially dangerous incidents." DECo can seal virtually any size or style stud in a housing of the customer's choice, from low volume R&D quantities to hundreds of thousands per year. 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. The StudSeal feedthroughs are widely used in air conditioning and refrigeration compressors, vacuum furnaces, and power distribution equipment. Specifically, these solutions are found in transformers, hermetically sealed compressors, pumps, magnetic bearing flywheels and heater circuits.
