Ultrahigh-voltage cable conversion device

The utility model belongs to an ultrahigh-voltage cable conversion device in the technical field of ultrahigh-voltage equipment. One side of the high-pressure oil tank (2) is provided with the ultrahigh-voltage socket (1), the other side of the high-pressure oil tank (2) is provided with the sealed voltage-sharing cable component (6), one end of the ultrahigh-voltage socket (1) in the high-pressure oil tank (2) is connected with the voltage-sharing cup (4), and one end of the sealed voltage-sharing cable component (6) in the high-pressure oil tank (2) is connected with the voltage-sharing cup (4). The ultrahigh-voltage cable conversion device is simple in structure, realizes transition of a short imported high-voltage cable plug into ultrahigh-voltage cable transmission, eliminates the problem that long-distance ultrahigh-voltage transmission is limited by an imported high-voltage plug seat and an ultrahigh-voltage cable, and ensures structural stability, reliability and safety at the same time. 本实用新型属于超高压设备技
