PURPOSE: To introduce a cable with a small pull force even if a cable pipeline assembly is curved. CONSTITUTION: In a cable pipeline assembly, a slide rib 3 is extended in waveform shape and an inverted part 7 is formed between sections 6 at a constant rotary angle (i); an equation Aγ=0.16b<2> zLKo is established, where a rib contact width is b, the number of slide ribs 3 formed at an equal interval on the peripheral surface of a pipeline inner wall is z, the inner radius of a cylindrical pipeline 2 is γ, and a rib contact part length between inverted parts is IK (In the expression, A indicates the contact area of a cable jacket at a cross point with a slide rib at the rib contact part and ranges from 4.5 to 32 mm<2> ). (ii); an angle g measured by the radian of the tip edge of the slide rib 3 satisfies g=ra/LKo and ranges from 0.001 to 1.2 rad (iii). |
