Fireproof type computer signal data cable and manufacturing method therefor

Abstract

The invention discloses a fireproof type computer signal data cable and a manufacturing method therefor. The cable comprises a plurality of cable cores, and a third ceramic fiber fire-resistant belt, a second metal shielding layer, a second silicon rubber composite material flame-retardant layer, a nanometer flame-retardant insulating layer and a flame-retardant outer sheath which are used for wrapping the multiple cable cores in sequence; and each cable core comprises a second ceramic fiber fire-resistant belt, a plurality of conductor core assemblies arranged in the second ceramic fiber fire-resistant belt, an insulating shielding layer and a first metal shielding layer which are used for wrapping the second ceramic fiber fire-resistant belt in sequence, and a first ceramic fiber fire-resistant belt and a first silicon rubber composite material flame-retardant layer used for wrapping each conductor core assembly in sequence. The fire resistance test of the cable meets the international GB / T 19216 standard as well as can meet the demands of G level, W level and Z level of the British BS 6387 standard; and in the test process, short circuit and open circuit of the cable do not occur.

Description

technical field [0001] The invention relates to a computer signal data cable, in particular to a fireproof computer signal data cable and a manufacturing method thereof. Background technique [0002] There are many types of products in the wire and cable industry, and the scope of application is very wide. It involves industries such as electric power, petrochemicals, communications, and manufacturing, and is closely related to various sectors of the national economy. RS cables are known as the "arteries" and "nerves" of the national economy. They are indispensable basic equipment for transmitting information and various signals and realizing electromagnetic energy conversion, and are necessary basic products in the future information society. Especially in fast-growing developing countries like China, the huge demand for infrastructure and supporting facilities is self-evident. [0003] There are two ways of serial communication and parallel communication for data transmis...

AI Technical Summary

Problems solved by technology

However, it can be seen from the material of the RS-485 computer signal data cable that its flame retardant performance is very poor; and as the incidence of electrical fires in fires increases year by year, the requirements for fire protection of wires and cables are becoming increasingly urgent
