AI Technical Summary

Technical Problem

Wind power cables are prone to core breakage and conductor fatigue cracking under complex and extreme working conditions, leading to power transmission failure and high maintenance costs.

Method used

The design adopts a multi-segment connected core body, combined with a buffer spiral segment, a spiral spring and a stress ring. The elastic deformation of the spiral spring diverts the tensile force, and the buffer unit provides anti-compression and anti-torsion protection, ensuring that the core body has no axial preload under normal conditions, thus avoiding direct stress and breakage.

Benefits of technology

It enables tensile stress diversion and adaptive deformation of cables under complex working conditions, avoids direct conductor breakage, improves the compressive and torsional strength and structural stability of cables, and extends service life.

Abstract

The application relates to the technical field of cables, in particular to a high-conductivity corrosion-resistant wind power cable, which comprises an outer protective structure and a wire core body arranged in the inner part of the outer protective structure, the wire core body is designed in a multi-section connecting mode, the middle part of the wire core body is a buffer spiral section, the two end parts are connecting smooth sections, and an expansion unit is arranged on the outer periphery of the wire core body. The wire core body is designed in a sectional mode, the middle part is provided with a buffer spiral section, and a built-in double-coil spiral spring is matched, when the cable is pulled, the spiral spring is firstly elastically stretched, drives the wire core buffer spiral section to synchronously and adaptively lengthen, external force does not directly act on the wire core body, the wire core only elastically stretches in the whole process and does not bear active tension, the problem of wire core breakage and tearing is completely solved, after the external force is eliminated, the spiral spring is automatically reset, the wire core returns to a stress-free relaxation state, there is no metal fatigue hidden danger, and the use requirement of the wind power cable is met.
