Abstract

The invention discloses an aluminum metal sheathed fireproof cable. The cable is composed of a sheath and a cable core, wherein the cable core is provided with at most five wire cores; , phlogopite layer, aluminum metal sleeve and isolation sleeve, and a fireproof layer is also arranged in the cable core. In the present invention, the cable has good flexibility and bending resistance by using a plurality of single-filament conductors; by using fluorine tape as a high flame-retardant insulating tape, the cable has high insulation resistance; by using continuous seamless extrusion The aluminum metal sleeve makes the cable waterproof, anti-rat ants and stray current, as well as anti-pressure and anti-interference; at the same time, the aluminum metal sleeve can also be used as the PE wire or PEN wire of the cable, so as to prevent electric shock during electricity use. The occurrence of accidents; by using metal hydrate composed of aluminum hydroxide, magnesium hydroxide and binder as a fireproof layer, the cable has good fire resistance.

Description

technical field [0001] The invention relates to the technical field of cable fire prevention, in particular to an aluminum metal sheath fireproof cable. Background technique [0002] With the improvement of social safety awareness, fire-resistant cables are widely used in high-rise buildings, electric power, chemical industry, engineering construction and other fields. At present, fire-resistant cables are realized through the introduction of high-temperature-resistant insulating materials, such as the combination of mica tape and cross-linked polyethylene insulation. Anti-interference ability. [0003] The fire-resistant cable with the above structure has the following defects: the insulation is composed of a combination of high-temperature-resistant mica tape and non-high-temperature-resistant flammable cross-linked polyethylene, and the cross-linked polyethylene layer plays the main role of moisture-proof, sealing and electrical insulation under normal conditions , and ...
