Problems solved by technology

[0003] And the problem that existing technology exists is: existing wind generator cable generally all is power transmission, mechanical equipment control cable, signal transmission cable all is to use separately, uses like this and not only has increased the use cost of cable, and connects a piece like this. It increases the inconvenience of cable installation, secondly, it increases the unsafe factors in the process of using the cable, and thirdly, once the cable fails, it will bring difficulties to the cable maintenance

Abstract

The invention discloses an optical fiber compound wind power cable which comprises a cable core. A packing layer is arranged at a gap position of the cable core, high-strength aramid yarn is woven on the outside of the cable core, and an outer protective sheath wraps the outermost layer of the cable core in an extrusion mode. The cable core is formed by stranding an electric power transmission cable core and a control cable core in parallel. The control cable core is formed by stranding three control cable core bodies and one optical fiber unit, and an inner protective sheath wraps the outside of the control cable core in an extrusion mode. The optical fiber compound wind power cable is mainly used in a wind driven generator tower to conduct wind driven generator electric power transmission, signal transmission and device control. The cable integrates electric power transmission, signal transmission and a control circuit, is resistant to low temperature, torsion and cracking and has good tensile property.

Description

technical field [0001] The invention relates to the field of electric wires and cables, in particular to an optical fiber composite wind energy cable. Background technique [0002] At present, the rapid development of the wind power industry, as an important part of the wind power industry - wind energy cables, has also achieved unprecedented development. Wind energy cables are used in towers and harsh environments, and there are high requirements for the tensile strength, low temperature resistance, twist resistance and service life of the cables. In order for the wind power generation system to operate normally, the power transmission, mechanical control, and signal transmission of the cable need to be coordinated and completed. [0003] And the problem that existing technology exists is: existing wind generator cable generally all is power transmission, mechanical equipment control cable, signal transmission cable all is to use separately, uses like this and not only has...
