The transmission of electric power is realized by using a transformer to boost the electric energy generated by a generator and then connecting the electric energy to a power transmission line through control equipment such as a breaker and the like. According to the structural form, the power transmission line is divided into an overhead power transmission line and a cable line. The overhead transmission line consists of a line tower, a lead, an insulator, a line hardware fitting, a stay wire, a tower foundation, a grounding device and the like and is erected on the ground. Power transmission is classified into ac power transmission and dc power transmission according to the nature of the transmitted current. Dc transmission was first successfully achieved in the 80's of the 19 th century. However, the voltage of the dc transmission is difficult to increase continuously under the current technical conditions, so that the transmission capacity and the efficiency are limited. At the end of the 19 th century, direct current transmission was gradually replaced by alternating current transmission. The success of alternating current transmission has already met a new era in the electrified society of the 20 th century.
Among the power transmission lines, the cable conductor is the most important power transmission line, and is made of one or more mutually insulated conductors and an outer insulating protective layer, and transmits power or information from one place to another.
