At present, 61 percent of line emergency repair faults occur at cable joints. At present, the wiring or jumper wire in the power transmission and distribution line mainly adopts the modes of hand-tying type, parallel groove clamp type, puncture wire clamp type, C-shaped wire clamp type and the like. Among them, the most conventional hand-bound (about 80%) and relatively new C-type clamps are mainly used. Under the condition of low power consumption in the past, the hand-binding type with lower cost is basically adopted to meet the requirements, but along with the continuous increase of the power consumption of users, the mode of continuously adopting the hand-binding wire obviously cannot meet the requirements, such as the electrochemical corrosion problem of copper and aluminum under heavy current, the problem of loosening caused by expansion and contraction caused by heat and the problem of aging and falling of an adhesive tape between the binding wires are all difficult to solve. In order to solve the problems of the hand-binding wire mode, the parallel groove wire clamp mode, the puncture wire clamp mode, the C-shaped wire clamp mode and the like are adopted, but the modes have high requirements on the installation process, particularly the wire diameter of the wire and a wire connecting hole in the wire clamp are strict, the design effect can be achieved only by matching the wire diameter and the wire connecting hole one by one, and in fact, the outer diameter of the conductor of the insulated wire is rarely just the nominal outer diameter during design, so that the wrong type is generated during the construction and maintenance process, the clamp type is not tight due to large size, the overcurrent is influenced, and the wire burning is easy to generate; the clamp type is small, so that the clamp cannot be pressed down and the self-locking function is lost. Meanwhile, the wire clamp is difficult to store and select spare parts due to the fact that the wire clamp is large in specification.
