Abstract

The invention discloses a cold contraction cable accessory pipe, which comprises an accessory, a supporting pipe, a first pull head and a second pull head, wherein the supporting pipe is installed at the inner side of the expanded accessory, the supporting pipe is a hollow cylinder formed by spirally winding lining strips, the first pull head and the second pull head are respectively arranged at both ends of the supporting pipe, and the first pull head and the second pull head are respectively formed in the mode that the lining strips penetrate through the supporting pipe and extend to the outside of the supporting pipe. In the mode, the supporting pipe of the cold contraction cable accessory pipe provided by the invention sleeves a cold contraction cable accessory, the supporting pipe then forms into the shape of strips to be drawn out through the pull heads, and the accessory is kept on the cold contraction cable accessory; moreover, the two pull heads are arranged, and strip-drawing positions can be randomly selected, so that the cold contraction cable accessory pipe is convenient to use; meanwhile, the cold contraction cable accessory pipe has smaller resistance and is easy to withdraw, so that the cold contraction cable accessory pipe has the advantages of high strip-drawing speed and short strip-drawing time, and the sealing performance of the cold contraction cable accessory is guaranteed.

Description

technical field [0001] The invention relates to the field of cable sets, in particular to a cold-shrinkable cable accessory tube. Background technique [0002] With the adjustment of the voltage level of the national grid, the voltage level of indoor and outdoor cables continues to increase, and the voltage level requirements for cold-shrinkable cable accessories are also increasing. Domestic industrial production is not yet possible, and they are completely dependent on imports. [0003] When in use, the inner-lined spiral tube should be put on the rubber tube first, and the inner-lined spiral tube will stretch the rubber tube, and then the inner-lined spiral tube will be placed on the high-pressure cold-shrinkable cable accessory, and then the inner-lined spiral tube will be pulled out, and the rubber tube will be pulled out. The tube remains on the high pressure cold shrink cable attachment. Therefore, it is required that the lined spiral pipe must be easy to extract. ...
