The cable accessories are a very important process in the construction of the cable. The quality of the cable accessories will directly affect the quality of the whole electrical engineering construction. Therefore, in the process of cable construction, we should make a comprehensive analysis of the various state aspects of the cable in order to ensure the long-term and effective stability of the cable. This is also the main role of the cable accessories work. At present, in the process of cable construction, we carry out the cable work mainly by moving the high voltage to the bottom of the cable to keep the balance of the electric field distribution in the middle end of the cable so as to ensure the stable operation of the cable, so as to reasonably stabilize the release voltage and improve the quality of the electric power for the people. They are used.
