Application and Analysis of XLPE Cable Waterproof Joint
If the underground substation cable protective layer seepage problem can't be solved, it will lead to cable operation accidents and affect the power supply reliability of power system. According to the underground substation protective layer multiple occurrences of cross-linked polyethylene insulated cable water seepage accident, the main cause of the cable protecting layer seepage were analyzed. This paper describes the design of FSJ - 10/3.3 type cable waterproof joint, the installation technical requirements, notes and the application performance. To further promote and enhance the cable waterproof joint application of the results, the cable waterproof technology applied to high voltage cross-linked cable has a long way to go.
