Abstract

The invention discloses a low-temperature and torsion-resistant wind power generation cable and a preparation method thereof, comprising the following preparation steps: step a, wire drawing annealingto obtain a conductor; B, strand that conductor to obtain a guide core; C, wrap an isolation layer around that guide core; D, extrude an insulating layer out of that isolation layer; E, weave a shield layer outside that insulate layer; (f) wrap an elastic layer around that shield layer; (g) weave an anti-crack layer out of that elastic layer; (h) extrude an outer sheath lay outside that crack-resistant layer; Step i: Apply an anticorrosive layer on the outer sheath layer. The invention improves the preparation method of the existing cable for wind power generation, so as to improve the problems of poor low temperature resistance, poor torsion resistance, poor tensile resistance, poor corrosion resistance, short service life and the like of the existing wind power generation cable, and thewind power generation cable prepared by the invention has long service life and excellent low temperature resistance, torsion resistance, tensile resistance, corrosion resistance and the like.

Description

technical field [0001] The invention relates to the technical field of cables for wind power generation, in particular to a low-temperature and torsion-resistant wind power cable and a preparation method thereof. Background technique [0002] With the continuous acceleration of the world's industrialization process, the energy consumption is gradually increasing, and the discharge of global industrial harmful substances is increasing day by day, resulting in abnormal climate and more disasters. Therefore, energy and environmental issues have become two important issues facing the world today. . The crisis caused by energy issues and the increasingly prominent environmental problems have made people realize that the development of clean and renewable energy is an objective requirement for ecological environment protection and sustainable development. Wind is a non-polluting energy source. Using wind power to generate electricity is very environmentally friendly and can gener...
