AI Technical Summary

Technical Problem

In existing low-voltage cables, although the outer sheath is made of environmentally friendly materials, the internal materials are mostly non-environmentally friendly, resulting in a low overall recyclability rate and environmental pollution problems.

Method used

The cable is designed using all environmentally friendly materials, including the cable conductor, modified polypropylene insulation reinforcement layer, polypropylene filler rope, and modified polypropylene outer sheath, ensuring that all parts of the cable are recyclable. It uses Class 1 or Class 2 copper conductors to ensure conductivity, and the insulation and sheath layers are made of low-smoke, halogen-free, and low-toxic materials.

Benefits of technology

This improves the insulation and mechanical properties of the cable, while also enabling the recyclability of all parts of the cable, reducing environmental pollution and costs associated with the disposal of waste cables.

Abstract

The utility model relates to a recyclable environment-friendly low-voltage power cable, and belongs to the technical field of environment-friendly cables. According to the technical scheme, a modified polypropylene insulation reinforcing layer (2) is extruded outside a cable conductor (1) to form a wire core, a plurality of wire cores are cabled and then are wrapped by a polypropylene wrapping tape (4), polypropylene filling ropes (3) are filled between the polypropylene wrapping tape (4) and the wire cores, and a modified polypropylene outer sheath (5) is extruded outside the polypropylene wrapping tape (4). The beneficial effects of the utility model are that the insulating layer and the sheath layer of the cable are both made of high-performance modified polypropylene materials, and the filler of the cable is made of polypropylene filling ropes which have the characteristics of low smoke, zero halogen and low toxicity, so that the comprehensive insulation protection performance and mechanical performance of the cable are improved, and the service life of the cable is prolonged. The main metal and non-metal materials of the cable can be recycled, and the recycling of the materials reduces the waste cable treatment cost and environmental pollution.
