[0017] Furthermore, the cleaning support component is a support sleeve, the support sleeve is fixedly connected to one end of the support core, and a plurality of pull ropes are fixedly connected to the support sleeve.

[0018] The utility model provides a cable terminal head cold shrink sleeve, which has the following beneficial effects:

[0019] (1) The cable terminal head cold shrink sleeve uses an insulating filler to prevent the outer sleeve and the inner sleeve from being overheated during use, thereby improving safety during use.

[0020] (2) The cable terminal head cold shrink sleeve can clean the surface of the cable by using a cleaning film to prevent foreign matter from remaining on the cable surface, such as sand, metal shavings, tape, etc. on the inner wall of the cold shrink sleeve, thereby causing the electrical performance of the cable system to deteriorate and even cause failures.
