Abstract

The present invention discloses a cable and optical cable data cable integration bus and a preparation method thereof. The cable and optical cable data cable integration bus comprises a bus cable inner core formed by a transmission cable, an optical cable and a data cable, and a ceramic fiber fire-resistant belt, a fifth silicone rubber composite material fire-retardant coating, a nanometer fire-retardant insulating layer and a fire-retardant outer sheath which coat the outer portion of the bus cable core in order; and the position between the bus cable inner core and the ceramic fiber fire-resistant belt is filled with third fire-resistant filling materials. The fire resistance test of the cable can satisfy the requirement of the national standard GB / T19216 and can satisfy C-grade, W-grade and Z-grade requirements specified in the England BS6387 standard; and moreover, the cable is neither short-circuit nor open-circuit in the test process.

Description

Technical field [0001] The invention relates to the field of Internet of Things, in particular to a cable, optical cable and data cable integrated bus and a preparation method thereof. Background technique [0002] With the rapid development of the national economy, the use and laying density of cables are getting higher and higher; especially in the field of the Internet of Things, the Internet of Things fieldbus involves the transmission of frequency division multiple data signals, voice signals, image signals and power signals. Existing technologies use optical fibers, data lines, and power lines to transmit the above-mentioned signals and data, resulting in spider web-like cables covering the entire site, which not only affects the stability and reliability of signal transmission, but also prevents interference with the layout of other equipment on the site. And installation. [0003] In recent years, fires caused by electricity have increased year by year, and fires caused by...
