With XLPE cables are widely put into operation in the city underground power system, it is more and more important of the stability of 110kV cable lines. The prefabricated dry terminal due to lack of firmly fixed and other shortcomings, Cable breakdown faults are easy. In recent years, several terminal breakdown prefabricated dry cable typical case in shandong power network, a comprehensive analysis of the breakdown faults reason, combined with the operation experience, put forward the new 110kV cable line prefabricated dry terminal platform installed in the transport line, the new 110kV cable line prefabricated dry terminal comprehensive inspection, strengthen the infrared temperature measurement of charged detection, transformation timely preventive measures. Through the development of 110kV cable line full prefabricated dry terminal breakdown prevention measures, it can effectively reduce the probability of the faults and improve the reliability of high voltage cable line operation.
