The invention provides a grasping force reinforcing method for a cold contraction type stress tube type cable terminal. The method comprises the following steps of an insulating band wrapping step: wrapping a stress tube of the cold contraction type stress tube type cable terminal with an insulating band to form a wrapping body; a semi-conductive band wrapping step: wrapping the insulating band with a semi-conductive band; and a waterproof band wrapping step: wrapping the semi-conductive band with a waterproof band. According to the grasping force reinforcing method disclosed by the invention, the cable terminal is reinforced and repaired by common cable auxiliary mounting auxiliary materials, such as the insulating band, the semi-conductive band, the waterproof band and the like, and by adopting a manual wrapping way, so that the grasping force of the cable terminal is improved, operational reliability of the cable terminal is further improved, and hidden danger and risk in cable operation caused by insufficient grasping force of a silicone rubber outer layer is lowered; and meanwhile, the problem of waste of operation and maintenance resource caused by unnecessary replacement of the cable terminal is avoided.
