A cold-shrinkable terminal of an optical fiber composite medium-voltage cable and its installation method

Abstract

The invention discloses a cold shrink terminal for an optical fiber composite medium-voltage cable. The cold shrink terminal is structurally characterized in that an insulating self-adhesive tape is wound on an optical cable of the optical fiber composite medium-voltage cable, two layers of small-diameter cold shrink pipes are contracted on an outer layer of the insulating self-adhesive tape, the optical cable is sleeved into one finger sleeve of four core finger sleeves, a sealing pipe is contracted on the optical cable, at least one layer of sealing gum is wrapped from a certain distance below a finger sleeve end opening upwards to a large-diameter cold shrink pipe end, the sealing gum and filling gum are wrapped by an adhesive tape, and at least one layer of adhesive tape is wound at the contracted sealing pipe end. The invention further discloses a mounting method of the cold shrink terminal. In the cold shrink terminal for the optical fiber composite medium-voltage cable, the four core finger sleeves serve as branch portions of the optical cable, namely, independent branch ports are provided for the optical cable, sealing and waterproof performances of the optical cable are improved by thickening the outer diameters of branch port sections of the optical cable and winding the filling gum and the sealing gum, and the cold shrink terminal matched with the optical fiber composite cable is realized.

Description

technical field [0001] The invention relates to a wire and cable cold-shrinkable terminal, in particular to a cold-shrinkable terminal for optical fiber composite medium-voltage cables and an installation method thereof. Background technique [0002] With the development of smart grid construction, the use of fiber optic composite cables continues to grow, and because the fiber optic composite power cable has both power transmission and optical fiber communication functions, its appearance reduces the total cost of engineering construction investment and operation and maintenance. Technical and economic significance, so the use of optical fiber composite medium voltage cables will also be a general trend. Then its appearance and use will definitely use special fiber optic cable accessories that match it. Most of these accessories in the market are imported, and the manufacturing is complicated and costly. At present, there are only two fields in China: the cable accessories...

Problems solved by technology

Most of these accessories in the market are imported, and the manufacturing is complicated and costly. At present, there are only two fields in China: the cable accessories industry and the optical cable accessories industry. The industry technology is too far apart, which affects the integration of the two.
