Abstract

The invention discloses a high-flexibility medium voltage cable for use in an offshore wind turbine bin. The high-flexibility medium voltage cable comprises conductive units, a control unit, a light unit, a shielding layer and an outer protecting bush layer, wherein taped covering layers (2), inner shielding layers (3), insulating layers (4), outer shielding layers (5) and metal shielding layers (6) are sequentially arranged outside copper conductors (1) of the conductive units; an insulating layer (8), a filling layer (11) and an inner protecting layer (9) are sequentially arranged outside acopper conductor (7) of the control unit, and the light unit (10) is located in the control unit; a filling layer (12) is located between the conductive units and the control unit; and a total shielding layer (13) and the outer protecting bush layer (14) are arranged outside the conductive units. According to the technical scheme, by utilizing a novel structure and materials, the cable has relatively high flexibility, wear resistance, acidity resistance, low temperature resistance and excellent shielding performance and integrates functions of power transmission, signal control and data transmission, so that the construction cost is lowered, and the cable is relatively applicable to offshore wind generation systems.

Description

technical field [0001] The invention relates to a power and signal transmission cable, in particular to a highly flexible medium-voltage cable used in the cabin of an offshore wind power generator. Background technique [0002] Currently, offshore wind power is developing rapidly around the world. Statistics show that by the end of 2016, the global installed capacity of offshore wind power reached 14.384 million kilowatts. With the joining of countries such as China and the United States, the development speed of this industry is expected to further accelerate in the next few years. The "Thirteenth Five-Year Plan" for wind power development points out that by the end of 2020, the cumulative installed capacity of wind power connected to the grid will reach more than 210 million kilowatts, of which the installed capacity of offshore wind power will reach more than 5 million kilowatts (new capacity accounts for 57% of the country's new increase). -In 2016, the accumulative gr...
