Title:
OPTICAL FIBER COMPOSITE FIREPROOF CABLE AND INTELLIGENT EARLY WARNING COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/093440
Kind Code:
A1
Abstract:
An optical fiber composite fireproof cable and an intelligent early warning communication device, which relate to the technical field of optical communication transmission, and which have optical communication capabilities, and good high temperature resistance and combustion resistance. The foregoing cable and device may be combined with a fire early warning system or a monitoring device to promptly detect and warn of disasters in the early stages of a fire, thus providing a time safeguard for escape and disaster relief. The optical fiber composite fireproof cable comprises a communication light unit (1), an early warning light unit (2) and at least three power transmission units (3). The communication light unit (1), the early warning light unit (2), and the power transmission units (3) are twisted to form a cable core. The communication light unit (1) consists of a loose tube (101), a plurality of communication optical fibers (102) located in the loose tube (101), and a polyolefin sheath layer (103) extruded on an outer surface of the loose tube (101). The early warning light unit (2) comprises a plurality of temperature measuring optical fibers (201), a spiral steel tube (202), a Kevlar fiber reinforced layer (203), a stainless steel braided layer (204) and a Teflon sheath layer (205). The power transmission units (3) comprise copper conductors (301), mica tape layers (302) covering outer surfaces of the copper conductors (301), and polyolefin insulation layers (303). A filler (5) is provided between a glass fiber cladding layer (4) and the cable core.
