Abstract

The invention relates to a fire-proof type signal cable and a production method thereof. The cable comprises a plurality of cable inner cores as well as a third ceramic fiber fire-proof belt, a second metal shielding layer, a second silicone rubber composite material flame-retardant layer, a nano flame-retardant insulating layer and a flame-retardant sheath which wrap the plurality of cable inner cores sequentially; each cable inner core includes a second ceramic fiber fire-proof belt, a plurality of conductor core groups in the second ceramic fiber fire-proof belt, an insulating shielding layer and a first metal shielding layer which wrap the second ceramic fiber fire-proof belt sequentially, as well as a first ceramic fiber fire-proof belt and a first silicone rubber composite material flame-retardant layer which wrap each conductor core group sequentially. A fire proof test of the cable not only satisfies requirements of international GB / T 19216, but also satisfies requirements of a C level, a W level and a Z level prescribed in British BS6387 standards. In a test process, the cable will not be short circuited or open circuited.

Description

technical field [0001] The invention relates to a computer signal data cable, in particular to a fireproof signal 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 transmission between c...
