Problems solved by technology

As a traditional copper core cable in China, not only the cost is high, but the large self-weight increases the installation cost; with the rapid development of my country's economy, the domestic copper mine resources are scarce, which leads to the high cost of copper core cables; in addition, copper core cables There will be creep phenomenon. After a long time, the cable will become weak and loose, which will cause safety problems in severe cases.

Abstract

The invention discloses a direct-current cable, which comprises a core material, wherein the core material is formed by twisting an aluminum-based alloy wire and an iron-based alloy wire; a filler coats the outside of the core material; a damp-proof layer is arranged outside the filler; a lightweight woven mesh coats the outside of the damp-proof layer; and an external protection layer is arranged outside the lightweight woven mesh. The damp-proof layer can improve the waterproof property and the damp-proof property of a product and can ensure the service lifetime of the material; and the protection layer can effectively play a protecting role; and the raw materials are simple and easy to obtain.

Description

technical field [0001] The invention relates to a DC cable and belongs to the technical field of cables. Background technique [0002] At present, most of the cables used in my country's construction industry are traditional cables with copper conductors. As a traditional copper core cable in China, not only the cost is high, but the large self-weight increases the installation cost; with the rapid development of my country's economy, the domestic copper mine resources are scarce, which leads to the high cost of copper core cables; in addition, copper core cables There will be creep phenomenon. After a long time, the cable will become weak and loose, which will cause safety problems in severe cases. Contents of the invention [0003] A DC cable, including a core material, the core material is made of twisted aluminum-based alloy wire and iron-based alloy wire, the core material is covered with a filler, the filler is a moisture-proof layer, and the moisture-proof layer is ...
