Publication number: 20230368942Abstract: A sealed cable assembly includes a jacket enclosing a plurality of insulated wires. Each insulated wire includes a bare wire covered by surrounding insulation, and a cable plug or connector is electrically connected with the bare wires. A sealant surrounds the insulated wires in an air gap between the jacket and the insulated wires in a location at or near the cable plug or connector, and the sealant fills the air gap at the location to prevent or reduce fluid loss through the cable in an immersion cooling system. The cable assembly can also be sealed at an in-between section away from the cable plug or connector. The cable assembly is wrapped with a weatherproof film or tape at the location of the sealing to further prevent or reduce fluid loss through the cable.Type: ApplicationFiled: January 29, 2020Publication date: November 16, 2023Inventors: Richard Yufeng Liu, John P.
