Latest Patents

Among his latest innovations is a groundbreaking superconducting cable. This invention is designed to maintain a predetermined thermal insulation property without the need for a vacuum thermal insulation structure. The superconducting cable comprises a core that houses a superconductor layer and an electrical insulation layer within a core-housing pipe, complemented by a thermal insulation member that operates in a non-vacuum state. A sealing member is also integrated to prevent moisture permeation into the thermal insulation member, ensuring reliable performance.

Another notable patent involves the method of producing submarine solid cable. This invention improves the structural integrity of submarine cables by suppressing the movement of insulating oil during use. The production method involves lapping insulating tapes, made from resin film, around a conductor, and impregnating this insulating layer with medium-viscosity insulating oil. The innovative production technique secures the impregnation path and narrows it to mitigate the movement of insulating oil, resulting in excellent insulation properties.
