High-strength scratch-resistant communication cable

Abstract

The invention provides a high-strength scratch-resistant communication cable. A cable main body part comprises a cable core, a protection layer structure on the outer side of the cable core, and a cable core sheath wrapping the outer side of the protection layer structure; and the protection layer structure comprises an inner lining layer, a fireproof layer and an outer shielding layer which are sequentially arranged from inside to outside. A reinforcing structure comprises a reinforcing core piece and a reinforcing structure sheath on the outer side of the reinforcing core piece, and the cable core sheath and the reinforcing structure sheath are connected into a whole through a sling; each insulating single wire comprises a data conductor and a data insulating layer wrapping the outer side of the data conductor; and the outer side of the data insulating layer is coated with an inner shielding layer. The cable provided by the invention can carry out electric energy transmission and signal transmission at the same time, and solves the problem of image transmission when a camera is configured on an electric hoist. Meanwhile, the design of the sheath structure and the cable core structure of the cable can further improve the tensile and compressive properties of the cable, ensure the use reliability of the cable, and prolong the service life of the cable.

Description

technical field [0001] The invention belongs to the technical field of cable production and design, and in particular relates to a high-strength, scratch-resistant communication cable. Background technique [0002] Electric hoist is a kind of special lifting equipment, which is installed on the crane and gantry crane. The electric hoist has the characteristics of small size, light weight, simple operation and convenient use. It is used in industrial and mining enterprises, storage docks and other places. The hoist accompanying cable is generally used for the connection between the electric hoist and the control switch, and is installed vertically on the electric hoist, and a camera is required in some special occasions. Although the existing electric hoist cables can realize power transmission, they cannot transmit images, and the function is relatively single. If you want to configure cameras and other facilities on the electric hoist, you need to lay additional signal cabl...

AI Technical Summary

Problems solved by technology

Although the existing electric hoist cables can realize power transmission, they cannot transmit images, and the function is relatively single. If you want to configure cameras and other facilities on the electric hoist, you need to lay additional signal cables next to the original cables. Poor, takes up a lot of space, and the structure of the cable part is complicated, confusing and easily damaged
