Wind energy cable and production method thereof

Abstract

The invention discloses a wind energy cable, comprising an outer sheath layer and at least one insulation core, wherein the insulation core comprises a conductor and an insulation layer, a longitudinal covered slippage-resistance layer is arranged between the conductor and the insulation layer, the slippage-resistance layer is a Teflon band, the conductor comprises a composite oxygen-free copper wire and a copper-clad steel wire, the composite conductor increases the tensile property and torsion resistance performance of the wind energy cable. The longitudinal covered slippage-resistance layer is arranged between the conductor and the insulation layer, so as to make the most of the self-lubrication, high intensity, high temperature resistance and low temperature resistance features of the Teflon band, ensure that the slippage resistance layer can bear high temperature and high pressure during the extruded insulation process, the conductor and the insulation layer can completely slip during the use, the insulation can not be damaged during slippage, and the requirement of low temperature resistance can be satisfied.

Description

technical field [0001] The invention relates to the technical field of electric wires and cables, and more specifically, relates to a wind energy cable and a manufacturing method thereof. Background technique [0002] With the continuous rise of traditional energy prices and people's increasing attention to environmental protection, the country has begun to vigorously develop renewable new energy and improve energy utilization has become indisputably two important aspects of sustainable energy development, of which wind energy is a new The power generation method with the most mature technology, the most large-scale development conditions and the most commercial development prospects in the energy industry, the development speed of wind power generation is impressive. The development of the wind power industry has put forward a demand for cables for wind power generation, and has been developed and put on the market by many cable companies. [0003] In view of the harsh env...
