Abstract

The invention discloses a device and method for installing a cable intermediate joint with a moisture-proof structure. The device includes a core wire stripping and cutting device, a grinding and polishing device, a silica gel sealing ring and a cable cold shrinkable intermediate joint. The core wire stripping and cutting device is used for The two sections of cable joints that need to be processed are respectively processed into the shape of pencil heads; the grinding and polishing device is used to polish and polish the cable pencil ends of the two sections of cables that have been stripped and cut; the silicone sealing ring is used for sleeve On the pencil end of the cable after being polished and polished; the cable cold-shrink intermediate joint is used to put two sections of cables covered with silicone sealing rings and perform glue filling and cold-shrink to complete the sealed connection of the two sections of cables. The device is used to implement the method. The invention solves the technical problem of potential safety hazards caused by poor sealing effect of the middle joint of distribution network cables at present.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a device and method for installing a cable intermediate joint with a moisture-proof structure. Background technique [0002] At present, during the connection construction of the power cable joints, the two sections of the cables all use pre-cooled intermediate joints. During the operation of the cable, the moisture will form water droplets between the electrical insulation and the insulation of the intermediate joint prefabricated part. When the water droplets accumulate to a certain amount, water trees will be formed. Under the action of an electric field, the cable will undergo water tree aging, which will eventually lead to breakdown of the insulation. This kind of harm is hidden, not easy to find, and usually not taken seriously by people. This hazard will greatly reduce the service life and safety of cables, and will bring huge economic losses and negative social impacts c...
