| Summary: | Ultra high voltage(UHV) power cable system is an economical, safe and reliable power transmission mode. In recent years, the concern about the traditional fossil energy pollution in the world and the determination to using clean energy have promote the medium distance UHV submarine power cable system. This paper designs and tests one kind of energy saving and loss reducing conductor applied to large cross-section submarine cable. Through reasonable process control, the paint film on the enamelled wire surface can be avoided being scraped during the process of twisting. According to the measured AC / DC resistance ratio, the optimized design for the subsequent conductor is put forward. Compared with the traditional conductor, the current carrying capacity of the conductor is improved, and it has a positive and practical significance for reducing the Joule loss of the cable system.
