In the pipe penetrating process, when the construction distance is long, the concave-convex texture of the pipe wall prevents the cable from smoothly penetrating through, and the conventional method is to shake the corrugated pipe, so that long time is needed. When the quantity of tail fibers is large, the tail fibers are easy to be wound in the pipe and not easy to penetrate the pipe, and troubles are brought to power communication construction.

Because the existing protective sleeve either lacks of a folding telescopic function or lacks of a structural design with an opening for facilitating threading; therefore, the work of installing the protective sleeve on the substation communication tail fiber consumes a great deal of time and energy, and the working efficiency is low.
