Hermetic Feedthroughs

What is an Electromechanical Assembly? An electromechanical assembly combines components and subassemblies that feature electrical and mechanical design elements to perform a specific function.   For Douglas Electrical Components, we manufacture electrical connectors and feedthroughs that feature both a mechanical interface as well as electrical components to transmit power and/or signal. Our electromechanical assemblies are integrated into larger […]

  Cable assemblies are a crucial component in transformer applications, as they are responsible for transmitting electrical power and/or signal to operate and monitor the transformer. There are several types of cable assemblies used in transformer applications, including bus bar assemblies, grounding cables, and high-voltage cables. Bus bar assemblies distribute electrical power within the transformer. They […]
