Cable protection tube

Abstract

The article according to this design is a corrugated cable protection pipe made of vinyl chloride for housing and protecting electric wires and cables inside, and is applicable to extra-high voltage cables, etc. as an alternative to CCVP pipes made of PVC. Here, in the case of CCVP pipes made of PVC, etc., when applying to the bent part, a dedicated bent pipe is required, but the article according to this design is different in that it can also be applied to the bent part. The characteristics of the cable protection pipe of this design are that it has the same pressure resistance as the conventional PVC pipe, and at the same time, it is a corrugated pipe with a predetermined flexibility, and moreover, it enables the flexibility to be controlled within a predetermined range. Specifically, as the corrugated shape, the peak part is formed in a straight line of a predetermined length, the valley part is also formed in a straight line of a predetermined length, and the height difference between the peak part and the valley part is set to a predetermined height according to the diameter of the protection pipe. The shape is such that the both ends of the straight peak part are connected to the both ends of the straight valley part of a predetermined depth by inclined surfaces at a predetermined angle and curves at both ends respectively.
