Portable hot melt repair method for outer sheath of high-voltage cable

The invention discloses a portable hot melting repair method for an outer sheath of a high-voltage cable, which comprises the following steps of: 1) heating and melting a granular raw material of which the material type is consistent with that of an outer sheath to be repaired into paste to obtain a paste raw material; 2) melting the cross section of the edge of the outer sheath to be repaired into a paste state; and (3) injecting the pasty raw material obtained in the step (1) into the part, needing to be repaired, of the cable, and fusing the pasty raw material with the pasty section in the step (2). According to the portable hot melt repairing method for the outer sheath of the medium-high voltage cable, the outer sheath of the cable can be quickly repaired, and the corresponding device is simple in structure, convenient to carry and good in repairing effect; the cable repair material is applied to cable repair, is convenient and rapid, and can fuse the same materials, so that the repaired cable reaches a
