Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome deficiency of the prior art, provides a kind of overall flexibility good, flameproof effect is desirable, safe and reliable to operation, environmental protection, the anaerobic metallic conductor flexible fire-proof cable of long service life.
Technical scheme: in order to solve the problems of the technologies described above, a kind of anaerobic metallic conductor flexible fire-proof cable described in the utility model, it comprises anaerobic metallic conductor, screen and insulating barrier is provided with in described anaerobic metallic conductor outside, described screen and insulating barrier are co-extruded, the Thickness Ratio of described screen and insulating barrier is 1:3, braid is provided with in described insulating barrier outside, described braid is formed according to 21 vertical woven that change by thin copper wire and aramid fiber silk, described anaerobic metallic conductor, screen, insulating barrier and braid composition conductive unit, described conductive unit is at least provided with two, packed layer is provided with in described conductive unit outside, lapping layer is provided with in described packed layer outside, fireprotection layer is provided with in described lapping layer outside, halogen-free and low-smoke flame-retardant polyolefin sheathed layer is provided with in described fireprotection layer outside, they form cable body, described conductive unit diameter accounts for the 1/3-2/5 of cable body diameter.
Described anaerobic metallic conductor is oxygen-free copper conductor.
Described packed layer is filling polyurethane layer or ethylene propylene diene rubber packed layer.
Described lapping layer is without shuttle woven fiberglass cloth lapping layer or silicon rubber lapping layer.
Described fireprotection layer is inorganic short fiber adhesive-layer.
Described conductive unit arranges two, and described conductive unit diameter accounts for 2/5 of cable body diameter.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model overall structure arranges rationally, adopt oxygen-free copper conductor, compare fine copper, fine aluminium cable is more stable, conductivity is higher, Thickness Ratio is adopted to be the screen of 1:3 and the coextruded layer of insulating barrier composition, shielding insulation effect is best, adopt coextruded structure simultaneously, the intensity at effective this position of raising, adopt the braid of thin copper wire and aramid fiber silk composition, effective flexibility improving entirety, adopt ethylene propylene diene rubber packed layer, filling effect is desirable, adopt inorganic short fiber adhesive-layer as fireprotection layer, can play and well isolate flame retardant effect, even if catch fire, also the pollution to the Nature can be alleviated, play environmental-protection function, described conductive unit arranges two, and described conductive unit diameter accounts for 2/5 of cable body diameter, again by each layer with the use of, conductive unit runs the most reliable, result of use is the most desirable, this Total Product long service life, realistic instructions for use.
