Problems solved by technology

[0004] However, the photoelectric composite cable has poor flame retardancy and poor anti-corrosion performance. It has potential safety hazards when used in trenches and other environments, and may release toxic gases such as hydrogen halides under extreme conditions. Therefore, it is urgent to develop a high-safety cable. photoelectric composite cable

Abstract

The invention provides a halogen-free low-smoke flame-retardant armored photoelectric composite low-voltage cable, and the cable sequentially comprises a photoelectric composite cable core, a halogen-free flame-retardant strip layer (1), a halogen-free low-smoke flame-retardant liner layer (2), an armored layer and an outer sheath (4) from the inside to the outside. The photoelectric composite cable core comprises a cable inner core (5), an optical unit (6) and a nonhygroscopic filling material (7). The cable inner core (5) comprises a conductive cable core (51) and an insulating layer (52) covering the exterior of the conductive cable core (51). The cable is higher in flame-retardant and fireproof performances.

Description

technical field [0001] The invention relates to the field of photoelectric composite cables, in particular to a halogen-free low-smoke flame-retardant armored optical fiber composite low-voltage cable. Background technique [0002] Optical fiber composite low-voltage cable combines the functions of optical fiber communication and power transmission. Compared with single-function transmission cables, it has the characteristics of high reliability data transmission, low price, and convenient connection. The space is small; the optical cable and the power line are integrated, avoiding secondary wiring and reducing engineering costs; it has good bending and lateral pressure resistance; it solves the communication problem of the power network. [0003] As one of the important cable products in the construction of smart grid, optical fiber composite low-voltage cable integrates the functions of communication and power, which can effectively realize the multi-network integration of...
