Difficult to find the point of failure after failure-prone and high voltage power cables take measures to further the use of long cables can also cause failure, such as "Buck change cable project," the aluminum cable is not put into the failure occurred (see the cable construction records into the processing and analysis), a total of more than 4,000 due to cable meters long, fault finding and processing great inconvenience. Is recommended to use some cable boxes docking, the number of joints in the middle of a cable not more than four, ease of construction and operation and maintenance, as well as subsequent development. Conclusion The high voltage power cable as urban development, power development and applied more widely, for cable runs of security requirements have become more sophisticated, and only do a good job in many ways to make the cable more secure and stable operation, in order to better play its power delivery capabilities. In recent years, high-voltage power cable (2007-2013) high-voltage power cable as one of the options of modern urban power transmission, has been widely used in the construction of power lines. Especially in 2011, Tongxiang City Zhendong District three pairs of cable engineering, high voltage power cable sales, Wuzhen midnight change cable projects on both sides of the road and in 2013 changed puyuan buck cable projects on a total of three projects put into operation more than 25 km high-voltage cables. In recent years, cable line fault, the extensive use of high-voltage cable is accompanied by a large number of cable failure. Incomplete statistics since 2007 by more than five times the cable fault occur every year, especially in the beginning of 2012 a substantial increase in Yulin high voltage power cable sales, such as the South cement 35KV incoming cable, hospital RMU plug cable head, Variable middle joint, mainly due to the transformation of 20 kV to 20 kV 10 kV step-up operation of the cable and the year has been on the run for over 10 years old cable majority, more than exclude cable fault caused by external damage. And the buck does not change the cable project has been put into the water Cable Joints failure, insulation shake test zero voltage test not hit up the situation.
