The utilization of the material on the design of the structure of the inside of cable and its inside and outside surface, has been largely fixed cable
Security performance.
For the problems in the relevant technologies, currently no effective solution has been proposed.
Utility model content
For above-mentioned technical problem in the related technology, the utility model proposes a kind of fireproof cables, can improve cable
Fire protecting performance.
To realize the above-mentioned technical purpose, the technical solution of the utility model is realized in：
A kind of fireproof cable, includes three conductors being distributed in isosceles triangle, and it is exhausted to be enclosed with rubber outside the every conductor
Edge layer, is provided with flexible filler between the rubber insulation of three conductors, outside the rubber insulation of three conductors
Glass-fibre fillers are provided with, the glass-fibre fillers are wrapped with flame-retardant layer, and the flame-retardant layer is wrapped with armouring
Layer, the armor are wrapped with protective layer.
Further, the soft filler is elastic string or high temperature insulation nylon.
Further, the rubber insulation of the soft filler and the conductor fits closely.
Further, the flame-retardant layer is low smoke, zero halogen polyolefin.
Further, the thickness of the flame-retardant layer is more than 1mm.
Further, the armor is aluminium wire.
Further, the protective layer is made of PVC material.
The beneficial effects of the utility model：Can improve the high temperature resistant of cable, anti-baked wheaten cake ability, prevent from answering internal environment and
Cable caused by external environment is on fire, and prevents from causing conductor lines exposed because cable rubs for a long time, can be good at pair
Cable is protected；The flexibility of cable entirety is stronger simultaneously, is more conducive to be laid with.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model
