Embodiment Construction

[0012] In order to better understand the technical solution of the present invention, it will be described in detail below through specific embodiments in conjunction with the accompanying drawings:

[0013] A flexible mineral fire-resistant photoelectric composite cable of the present invention comprises an outer sheath 1, a wrapping tape 3 and a mineral layer 2 arranged coaxially from the outside to the inside in a radial direction, and a plurality of cables 5 and a plurality of optical cables located in the mineral layer 2 4. The optical cable 4 wraps the multi-mode optical cable 40 and the single-mode optical fiber 41 for temperature measurement. The mineral layer 2 is filled with inorganic mineral powder which can be sintered at 950°C.

[0014] There are two advantages for the optical cable to be located in the mineral layer 2: first, the temperature of the optical fiber is the temperature inside the cable, which can be used for DTS temperature monitoring; Effectively re...

Abstract

The invention discloses a flexible mineral fire-proof photoelectric composite cable which comprises cable parts, optical cables, a mineral layer, a wrapping tape and an outer sheath, wherein at least one optical cable in the optical cables comprises a single-core multimode fiber and a single mode fiber with at least one core; the single-core multimode fiber and the single mode fiber are twisted together; the multimode fibers can be connected with a DTS; the cable parts and the optical cables are located in the mineral layer on the radial inner side of the outer sheath and fixed by the wrapping tape. The flexible mineral fire-proof photoelectric composite cable additionally has an optical cable signal transmission function based on a fire-proof cable and is internally provided with the multimode fibers as temperature sensors; the latest DTS is applied for real-time monitoring of the internal temperature of the cable; a fire risk caused by the cable can be eliminated; the special cable has a certain intelligent application basis.

Description

technical field [0001] The invention relates to a cable, in particular to a flexible mineral fireproof photoelectric composite cable. Background technique [0002] Whether in factories or buildings, the safety of electrical wiring is of paramount importance. According to the statistics of relevant national departments, the fires caused by electrical lines account for about 70% of the fire causes. The cable is not only the main body of the electrical circuit, but also a link that is difficult to carry out fire protection. At present, a wide variety of fire-resistant and fire-resistant cables on the market only have "fire-resistant" capabilities, and cannot effectively monitor their own ambient temperature, nor can they prevent and prevent fires in advance, which brings challenges to the application of such cables. extremely restrictive. How to increase the fire prevention function of the cable on the basis of the fire resistance function of the cable is the direction of ef...
