Abstract: Electric submersible pump cable is the main integral part of artificial lifting oil production equipment and the tool for transmission of electric energy and information signal. Foreign products have been used for a long period of time thanks to the complicated downhole working conditions and high technological requirements on ESP cable. This article makes detailed briefings about functions, structures, materials and technical indexes of a series of ESP cable independently developed by Zhongcheng Machinery Manufacturing Company. It also describes the concrete process requirements on the related parts, such as conductor, insulator, laying-up, sheath cover, oil-proof cushion and armor. Based on indoor experiment, field test and field application, a series of products have been produced, which can resist the temperature of 90℃ , 120℃ , 150℃ and 150℃ . They become the technological leaders at home with some of the targets reaching the international advanced level. Field application of those products shows good results and promising prospect. More efforts will be made to study the adaptability of the products so that they can resist high temperature, high pressure and high gas content.
