Problems solved by technology

[0002] At present, most of the cable conductors between outdoor power distribution equipment are connected by wire lugs. This method is to put the cable core inside the wire lug and squeeze the shape to make the cable core and the wire lug closely contact. This method is not only time-consuming and laborious, but also Moreover, the exposed contact wall of the wire nose is easy to oxidize and corrode the conductive parts, and short-circuit faults of line insulation often occur
[0003] In order to solve the above hidden dangers of insulation, there is a method of covering the wire lug with a silicone sleeve. The silicone sleeve has no sealing and insulating function, which can prevent the wire lug from contacting the wall from oxidation and corrosion, but it cannot protect the transmission line from short-circuit failure of the line insulation caused by the external environment.
