Abstract
The utility model relates to a high-voltage insulating sleeve which comprises a supporting ear, insulators and mounting holes arranged on the supporting ear, wherein the insulators respectively and axially penetrate into the mounting holes, a conductive layer is arranged between the inner walls of the mounting holes and the insulators, and both axial sides of the conductive layer are exposed. After a high-voltage wire penetrates through a transition wire hole in the insulators, the high-voltage insulating sleeve starts to work; if a leakage current passes through the insulators, the leakage current can move toward the conductive layer with lower electric potential so that the leakage current can be detected by only electrically connecting a current-detecting device and the conductive layer, and a conduction electrode electrically connected with the conductive layer is also arranged for facilitating the electric connection of the current-detecting device and the conductive layer. On the whole, the utility model solves the problem of the prior high-voltage insulating sleeve that the leakage current is inconvenient to detect.
