The cable line is divided into a cable body, and further comprises cable accessories, cable accessory equipment, cable accessory facilities and the like;
the cable body: indicating the cable section parts except for accessories such as cable joints, terminals and the like;
the vicinity of the cable: the components of the cable lines such as the cable terminal, the cable connector and the like are collectively called;
cable accessory equipment: the cable line accessory devices such as a shock absorber, a grounding device, an oil supply device, an on-line monitoring device and the like are collectively called;
cable accessory facility: cable line accessory parts such as cable brackets, identification tags, fireproof facilities, waterproof plug facilities, cable end stations and the like are collectively referred to as;
cable accessories are an integral part of the cabling and are not operable without accessory cables. The cable accessories are intermediate connections and terminal connections for the various cables in the cabling. Which together with the cable forms an electric power transmission network. The cable accessory not only can restore the performance of the cable, but also can ensure the extension of the cable length and the connection of the terminal according to the characteristics of the cable structure;
to improve the connection strength of the connection terminals, outdoor cables are typically expansion-contraction terminals that include a terminal body, a stress control cone, and an end seal connector. The end seal connection is sealingly connected to one end of the terminal body and the stress control cone is disposed within and proximate to the other end of the terminal body. The cable generally includes a conductor core, an inner insulating layer surrounding the conductor core, a conductive shield layer surrounding the inner insulating layer, and an outer jacket layer surrounding the conductive shield layer. Therefore, prior to installing the cable on the cold shrink terminal, a section of the outer jacket layer of the cable must be removed to expose a section of the plate conductive shield, then a portion of the exposed conductive shield is removed to expose a section of the inner insulation, and finally a portion of the exposed inner insulation is removed to expose a section of the conductor core to form the cable joint. Thereafter, a layer of grease, such as silicone oil, is coated on the exposed inner insulation layer of the cable connector, and then the cold-shrink type terminal is mounted on the cable connector coated with the layer of grease so as to fill the gap between the cable connector and the terminal body of the cold-shrink type terminal with the grease, and the filled grease can effectively reduce partial discharge and prevent occurrence of a breakdown phenomenon.
With respect to the related art in the above, the inventors consider that there are the following drawbacks: when the terminal is in rainy days, rainwater is easy to accumulate on the outer sheath layer, so that the rainwater permeates into the outer sheath layer, and further, the terminal is leaked or broken down.
