Alarm cable with rat resistance and moisture resistance functions

Abstract

An alarm cable with rat resistance and moisture resistance functions comprises copper conductors (1), crosslinked polyethylene jackets (2), an aluminum-plastic composite strip (3), a fire strip (4), an earth wire (5) and a halogen-free jacket (6), wherein each copper conductor (1) is covered with one crosslinked polyethylene jacket (2) to form an insulated cable core, the cable is covered with the aluminum-plastic composite strip (3) after the insulated cable cores form the cable, and the fire strip (4) is additionally arranged on an outer circle of the aluminum-plastic composite strip (3) and is covered with the halogen-free jacket (6). The alarm cable is characterized in that the earth wire (5) is further arranged between the fire strip (4) and the halogen-free jacket (6). The alarm cable has the functions of termite and rat resistance, non-toxic property, environmental protection, moisture resistance, oil resistance and corrosion resistance, spontaneous combustion of the cable or continued combustion when the cable meets open fire can be effectively prevented, and few hazardous substances and little toxic gas are generated.

Description

Technical field [0001] The invention relates to the technical field of cables and wires, in particular to a rat-proof and moisture-proof alarm cable. Background technique [0002] At present, most of the control cables used in cables are insulated and sheathed cables with ordinary polyvinyl chloride plastics, that is, the conductor is covered with PVC insulation, the core is covered with PVC inner sheath after the cable is formed, and the double-layer galvanized steel tape armor Installed, and then covered with PVC outer sheath. The cable has simple production process and qualified performance, so it is widely used. However, control cables such as alarm cables have general environmental adaptability, and they are often damaged by rats and ants. They are also poor in moisture resistance and corrosion resistance, and have a short life span. If they burn, they will emit dense black smoke and produce black solid derivatives. , And release irritating and toxic halogen acid gas, ...
