Optical fiber and control core composite type cable for wind power generation

Abstract

The invention discloses an optical fiber and control core composite type cable for wind power generation. The optical fiber and control core composite type cable for the wind power generation comprises a cable core, a packing layer is arranged in a gap position of the cable core, an inner protective sleeve wraps the outer portion of the cable core in a pressing mode, high-strength aramid yarns are woven outside the inner protective sleeve, and an outer protective sleeve wraps the outmost layer of the cable core. The cable core is composed of an optical fiber unit which is placed in the center of the cable core, four electric power transmission line cores and four control cable cores in a twisting mode. The optical fiber and control core composite type cable for the wind power generation is mainly used in a wind power generator tower and used for controlling electric power transmission of a generator, signal transmission of the generator and devices. The optical fiber and control core composite type cable for the wind power generation not only integrates electric power transmission, signal transmission and circuit control, but also has low temperature resistance, distortion resistance, cracking resistance, and a strong tensile property.

Description

technical field [0001] The invention relates to the field of electric wires and cables, in particular to an optical fiber and control core compound type cable for wind power generation. Background technique [0002] At present, the rapid development of the wind power industry, as an important part of the wind power industry - wind power cables, has also achieved unprecedented development. Cables for wind power generation 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...

AI Technical Summary

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
