Description

Technical field: [0001] The invention relates to the technical field of wires and cables, in particular to a high-strength and high-conductivity plastic cable. Background technique: [0002] In China, with the development of industrialization, power cables have become the main mode of power transportation, and copper core cables are the most widely used, occupying a major position in the cable application market. Copper core cables have the characteristics of low resistivity, high strength, and large carrying capacity. However, my country is a country that lacks copper resources. The contradiction between supply and demand of copper raw materials in the market in recent years has become prominent, causing the price of copper to soar all the way. In addition, the construction and installation of copper core cables are difficult, costly, and easy to steal. , easy aging and other shortcomings, people expect to have more suitable cables to replace copper core cables. [0003] W...
