Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1-4, the present invention provides a technical solution:

the utility model provides a take cable of armor protective layer, including sleeve pipe 1, sleeve pipe 1's inner space is equipped with the cavity 100 that is linked together with the external world, the inside cavity of cavity 100 is equipped with cable assembly 2, cable assembly 2 is including setting up the oversheath 20 in cavity 100 inside, penetrating inner chamber 200 around the inner space of oversheath 20 is equipped with, the inside cavity of inner chamber 200 is equipped with first armor protective layer 21, the inner space of first armor protective layer 21 is equipped with the wire 22 of the same specification of four groups, still be equipped with second armor protective layer 221 on the lateral wall of wire 22.

In this embodiment, the annular waterproof layer 11 is arranged on the inner cavity wall of the cavity 100, and when the cable is buried under the ground, the cable assembly 2 can be further protected by the waterproof layer 11 inside the sleeve 1, so that water contained in soil is prevented from entering the cable assembly 2 and affecting use.

Besides, the inner space of the inner cavity 200 is further provided with an inner sheath 201, the inner sheath 201 is located between the first armor protective layer 21 and the second armor protective layer 221, and the outer sheath 20 and the inner sheath 201 which are arranged can resist damage caused by external heavy pressure or foundation settlement, so that the service life of the cable is prolonged.
