[0002] Single-core means there is only one conductor in one insulation layer. When the voltage exceeds 35kV, most single-core cables are used. The relationship between its core and metal shielding layer can be regarded as the relationship between the coil and the iron core in the primary winding of a transformer. When current passes through the core of a single-core cable, magnetic lines of force will intersect the aluminum sheath or metal shielding layer, causing induced voltage at both ends.

[0024] The cutting knife 10 is slidably connected to the packaging bin 3, and a base plate 11 is fixedly connected to the inner side of the sleeve 2. There are three groups of base plates 11, all of which are on the inner side of the sleeve 2. The base plate 11 is in the shape of a fan-shaped plate, and the flat plate of the fan-shaped plate is fixedly connected to a mounting plate 111. The base plate 11 has threaded holes on the surface so that the position of the mechanism can be fixed.
