Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings.

[0012] Such as figure 1 As shown, the high-strength tensile wind power cable of the present invention includes a conductor 1, an insulating layer 2, an inner sheath 3, an aromatic yarn 4, and an outer sheath 5 from the inside to the outside. The insulating layer 2 and the inner sheath 3 are extruded and wrapped outside the conductor 1 by double-layer co-extrusion, the inner sheath 3 is braided with aramid yarn 4, and the aramid yarn 4 is extruded and wrapped with the outer sheath 5. Conductor 1 is made of annealed copper material, which is formed by twisting together a plurality of annealed copper wires.

[0013] Above-mentioned is only the preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and adjustments can also be made,...

Abstract

The invention discloses a high-strength tensile cable for wind power generation. The high-strength tensile cable for wind power generation comprises a conductor, an insulating layer and an inner protective layer, wherein the conductor is located in the center of the cable, sequentially wrapped by the insulating layer and the inner protective layer in an extruded mode and formed by twisting a plurality of annealed copper wires in the same direction, and aramid yarn is woven outside the inner protective layer and wrapped by an outer protective layer in an extruded mode. Because a metal reinforced layer in the prior art is replaced by the aramid yarn, the tensile property of the cable is guaranteed, the self-weight of the cable is reduced, and the production cost and erection difficulty of the cable are reduced; because the conductor is formed by twisting the annealed copper wires in the same direction, the softness of the cable is improved, the service life of the cable is prolonged, and safety in the use process is guaranteed.

Description

[0001] technical field [0002] The invention relates to a cable, in particular to a high-strength tensile cable for wind power generation. Background technique [0003] There are two types of single-core cables for wind power generation: high-voltage and low-voltage. Among them, the high-voltage single-core cables for wind power generation generally have a relatively large weight. Add copper tape shielding. This will inevitably increase the weight of the cable, and also increase the production cost and difficulty of erecting the cable. The low-voltage single-core cable for wind power generation uses less rubber material than the high-voltage single-core cable for wind power generation due to its low voltage level, so it is light in weight. It has an inside-out structure of conductor, isolation layer, and insulation layer. , sheath layer, and conductors are all twisted in different directions. Since the conductors of the cable are twisted in different directions, the ove...
