Problems solved by technology
At present, cable cold-shrinkable intermediate joints are commonly used in medium-voltage distribution networks. However, due to defects in construction technology and production quality of intermediate joints, after insulation breakdown occurs in cold-shrinkable intermediate joints, the faulty joint must be cut open. Location reworked middle joint
Since the conductor crimping tube is invisible, it is very easy to cause conductor damage during the cutting process, and even need to add cables to remake the intermediate joint
Significantly increases repair time and repair cost

The invention relates to the technical field of cable connection, in particular to a cable gas intermediate joint and a cable connection method. The cable gas intermediate joint comprises a left cylinder body, one end of the left cylinder body is detachably connected with a right cylinder body, and the non-connection ends of the right cylinder body and the left cylinder body are internally connected with prefabricated cold contraction parts; a closed gas chamber can be formed in the prefabricated cold contraction part, the right cylinder body and the left cylinder body, and SF6 gas is filled in the closed gas chamber. According to the cable gas intermediate joint and the cable connection method, the fault rate is low, fault repair is convenient, and the fault repair cost is low.
Description
technical field [0001] The invention relates to the technical field of cable connection, in particular to a cable gas intermediate joint and a cable connection method. Background technique [0002] The cable intermediate joint is the weak link of the cable line, and most of the cable line faults occur at the cable intermediate joint. At present, cable cold-shrinkable intermediate joints are commonly used in medium-voltage distribution networks. However, due to defects in construction technology and production quality of intermediate joints, after insulation breakdown occurs in cold-shrinkable intermediate joints, the faulty joint must be cut open. Location reworked the middle joint. Since the conductor crimping tube is not visible, it is very easy to cause conductor damage during the cutting process, and it is even necessary to add cables to re-make the intermediate joint. Greatly increased repair time and repair costs. [0003] Therefore, those skilled in the art are com...
