At this time, multiple groups of cables need to be processed and the joints of the two high-voltage cables that need to be butt-jointed are placed between two metal clamps. Then, by tightening the bolts and nuts, the metal clamps are tightly clamped to the cable joints to achieve fixation.

[0003] At the same time, the patent application number 201120262284.3 discloses a telescopic connection device for the intermediate joint of a disconnected high-voltage cable, which includes a threaded sleeve, two long-tube telescopic clamp pressure tubes, two physical threaded joints and two locking nuts.
