Description
Technical field
The present invention relates to a kind of cable, and in particular to a kind of fireproof cable.
Background technology
With the rapid development of the national economy, as the electric wire of national economy sustainer, its consumption and increasing using scope.At present, each field is to the quality of electric wire and the requirement more and more higher of performance, the fire triggered by electric wire, the aging of cable is also more and more, how to reduce fire incidence and occur fire when the death rate, fire prevention, environmental protection also turn into wires and cables industry developing direction.
The content of the invention
Goal of the invention：Of the prior art not enough reasonable there is provided a kind of structure setting the invention aims to overcome, fire protecting performance is excellent, the Novel fireproof cable of radial water-resisting.
Technical scheme：In order to solve the above-mentioned technical problem, a kind of Novel fireproof cable of the present invention, it includes conductor, screen layer is provided with outside the conductor, insulating barrier is provided with outside the screen layer, provided with fire prevention braiding layer outside the insulating barrier, they constitute conductive unit, the screen layer, insulating barrier and fire prevention braiding layer are co-extruded, the conductive unit is at least provided with two, packed layer is provided with outside the conductive unit, silicone resin layer is provided with outside the packed layer, fireprotection layer is provided with outside the silicone resin layer, aluminium-plastic tape is provided with outside the fireprotection layer, external sheath layer is provided with outside the aluminium-plastic tape, they constitute cable body.
The conductor is anaerobic copper conductor.
It is described fire prevention braiding layer by ceramic plastic wire and aramid fiber silk according to 1 repeatedly 2 vertical wovens form.
The thickness ratio of the screen layer, insulating barrier and braiding layer of preventing fires is 1：2：3.
The fireprotection layer is inorganic chopped fiber viscose glue fireprotection layer or inorganic mineral fireprotection layer.
The external sheath layer is halogen-free and low-smoke flame-retardant polyolefin sheathed layer.
Beneficial effect：Compared with prior art, its remarkable advantage is the present invention：Overall structure of the present invention sets reasonable, Integral sealing, using anaerobic copper conductor, compare fine copper, fine aluminium cable is more stable, electrical conductivity is higher, fire prevention braiding layer by ceramic plastic wire and aramid fiber silk according to 1 repeatedly 2 vertical wovens form, wherein ceramic plastic wire porcelain in flame combustion environment, form being dielectrically separated from for cable in hot environment, aramid fiber silk can improve the bulk strength of cable, using silicone resin layer, heat resistant silicone resin will be filled with the gap between packed layer, when cable fire, resin can solidify in itself, flame is prevented to enter, using inorganic chopped fiber viscose glue fireprotection layer or inorganic mineral fireprotection layer, isolation flame retardant effect well can be played, even if catching fire, also the pollution to the Nature can be mitigated, play environmental-protection function, using aluminium-plastic tape, radial water-resisting can be played a part of, using halogen-free and low-smoke flame-retardant polyolefin sheathed layer, further increase overall fire protecting performance, any pernicious gas is not produced during burning, this product operates steadily, it is safe and reliable, meet actual operation requirements.
