Shielded cable for engineering apparatus

Abstract

The invention discloses a shield cable for engineering equipment, which comprises a plurality of conducting wires, a shield layer, a paper belt, and an outer coating. The conducting wire includes a conductor and an insulating layer covering the conductor, wherein the conducting wire includes at least one signal line and a power line; the signal line also includes an inner copper net braiding layer braided at the periphery of the insulating layer; and the signal line is stranded with the power line to form a cable core. The shield layer covers the cable core, the paper belt covers the shield layer, and the outer coating covers the paper belt and is made of thermoplastic vulcanized rubber. Since the conducting wire consists of the signal line and the power line, one cable can not only transmit information signal but also transmit power signal, thereby saving the cost and facilitating the operation. The copper net braiding layer can effectively shield the interference, and the shield layer, the paper belt and the outer coating can further shield the interface, thereby improving the use performance of equipment. The outer coating layer is a low-smoke halogen-free layer, and can protect environment and resist UV ray and cold. Accordingly, the inventive cable is suitable for the engineering equipment working in hard field environment.

Description

technical field [0001] The invention relates to a cable for engineering equipment, in particular to a shielded cable for engineering equipment. Background technique [0002] At present, wires and cables have been widely used in industrial production, transportation, construction engineering and facilities, modern agriculture and scientific research, engineering equipment or military facilities, space and ocean detection, and have reached a ubiquitous state. With the step-by-step development of social and economic activities from depth to breadth, the varieties of wire and cable are constantly updated and improved, and the production volume continues to increase. For example, the construction of high-intelligence buildings requires computer network cables for hierarchical networking of hundreds or thousands of electronic computers; the establishment of urban public cable TV networks, the universal deposit and withdrawal of all banks in the city and even the country, and the d...

AI Technical Summary

Problems solved by technology

In addition, cables for engineering equipment are usually used in the field and in the workshop. The working environment is very harsh, the temperature changes greatly and they are directly exposed to ultraviolet rays. Therefore, the cables are easily aged and damaged, which will lead to equipment failure.

At the same time, once the outer layer of the existing conventional cable is aged and damaged, halogens are usually produced, causing environmental pollution

At present, the general-purpose cables cannot meet several main conditions of cables for engineering equipment with good shielding effect, anti-ultraviolet radiation, anti-aging and environmental protection.
