In the case of the above-mentioned refining furnace, the cable 1 is a special cable called a water-cooled cable, which is mainly used for current transmission of a high-current heating apparatus. The water-cooled cable is of a hollow water-through structure, is complex in structure, long in length and heavy in weight, and usually the length of one cable can reach more than 9 meters, and the weight reaches about 1 ton. The installation process becomes difficult due to the excessive weight of the cable. Specifically, the current installation method is that before installing the cable, the cable is suspended to the current output end 7 of the transformer or the current input end 8 of the refining furnace by adopting a flexible suspension strap, so that the flat connector of the cable is kept parallel to the connection plane face to face, and then the flat connector of the cable is installed on the connection plane by using a bolt. However, in the above-described process, it is difficult to keep the flat connector of the cable in face-to-face parallel with the connection plane, and the current method is to pry the cable with a crowbar so that the flat connector is kept in face-to-face parallel with the connection plane. The prying method by the prying bar not only consumes great manpower and operation time and has low operation efficiency, but also can damage the cable.
