Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] like figure 1 and figure 2 As shown, the right-handed stranded tensile power transmission cable includes a strengthening wire 1, an insulating layer 2 and a thin conductor 3; Combined thin conductor 3.

[0016] The diameter of the thin conductor 3 is smaller than the thickness of the insulating layer 2 , and the diameter of the reinforcing wire 1 is larger than the diameter of the thin conductor 3 . Multiple (more than 3) thin conductors 3 are arranged in the insulating layer 2 separated from each other.

[0017] The reinforcing wire 1 is a tensile fiber or tensile steel wire, the thin conductor 3 is an aluminum conductor or a copper conductor or a copper-nickel conductor, and the insulating layer 2 is a low-smoke halogen-free insulating layer.

[0018] The right-handed stranded tensile power transmission cable of the present invention adopts tensile fiber ...

Abstract

The invention discloses a right-handed intertwisted tension-resistant power transmission cable which comprises the components of a reinforcing wire, an insulating layer and thin conductors. The insulating layer wraps the reinforcing wire. The insulating layer is internally provided with a plurality of thin conductors which are intertwisted in a right-handed intertwisting manner. According to the right-handed intertwisted tension-resistant power transmission cable, a tension-resistant fiber or a tension-resistant steel wire is utilized as the reinforcing wire; furthermore an insulating layer is arranged outside the reinforcing wire, thereby realizing high safety; furthermore aluminum conductors or copper conductors or copper-nickel conductors for realizing electric conduction are arranged in the insulating layer, thereby reducing resistivity, saving energy and reducing emission; and thin conductors are utilized, thereby realizing better dielectric performance, good bending performance and high practicability of the cable.
