Environment-friendly network data cable and preparing method thereof

Abstract

The invention discloses an environment-friendly network data cable and a preparing method thereof. The environment-friendly network data cable comprises a resin insulating layer, several spiral alkali-free glass fibers are arranged inside the resin insulating layer, several cable cores are arranged at the inner side of the resin insulating layer and are mutually twisted, covering layers are arranged at the outer sides of all the cable cores, an inner protection layer is arranged at the outer side of the resin insulating layer, a mica belt is arranged at the outer side of the inner protection layer, is of a belt-shaped structure and is wound at the outer layer of the inner protection layer, polyethylene laminated film is arranged at the outer side of the mica belt, a shielding layer is arranged at the outer side of the polyethylene laminated film, an inner supporting cover is arranged at the outer side of the shielding layer, and an outer supporting cover is arranged at the outer side of the inner supporting cover. The environment-friendly network data cable has the advantages that the protection capability of a wire and the cable is comprehensively improved, the possibility of damage is reduced, the using safety of the cable is protected, an environment-friendly material is utilized, and the environment is better protected.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an environment-friendly network data cable and a preparation method thereof. Background technique [0002] Wires and cables are wire products used to transmit information of electric energy or magnetic energy and realize the conversion of electromagnetic energy. In a broad sense, wires and cables are called cables. In a narrow sense, cables refer to insulated cables. It can be defined as: composed of one or more insulated cores , and their respective possible cladding layers, total protective layer and outer protective layer, cables can also be added with non-insulated conductors. A cable in a narrow sense refers to an insulated cable, which can be defined as: consisting of one or more insulated cores, and their respective possible covering layers, total protective layer and outer protective layer, and the cable can also be additionally insulated conductors. . The existing outdo...

AI Technical Summary

Problems solved by technology

The existing outdoor cables are easy to be damaged during use, which affects the safety of the cables. At the same time, the improvement in tensile strength is not enough, and the internal materials are not environmentally friendly, which is easy to pollute the environment.
