Abstract
The invention discloses a fireproof low-smoke halogen-free cable comprising conductors and a sheath pipe which is arranged at the external side of the conductors. The sheath pipe comprises an internal sheath, an external sheath and a double steel layer which is arranged between the internal sheath and the external sheath. The external wall of each conductor is provided with a fire-resistant layer. The external wall of the fire-resistant layer is provided with an insulating layer. The gap between the conductors and the sheath pipe is provided with an insulating filling layer. With application of the mode, the fireproof low-smoke halogen-free cable is simple in structure and solid and durable and has high wear resistance and excellent fireproof performance so that the flame retardation effect is great and the service life is long.
Description
Technical field
The present invention relates to low-smoke halogen-free cable field, particularly relate to a kind of fireproof low-smoke halogen-free cable.
Background technology
Polrvinyl chloride (PVC) is at the highest a kind of macromolecular material of cable industry utilization rate, and PVC CABLE MATERIALS has well
Electric insulating quality, have certain mechanical strength, the feature such as fire-retardant, inexpensive and wide material sources, as electric wire insulation and
Sheath has obtained extensively application.Yet with the shortcoming on this body structure of PVC, it is impossible to meet the application of some special occasions.Pass
The polyvinyl chloride cable covering material of system is made up of inflammable high molecular synthetic material, and anti-flammability can not at some special occasions
Reaching requirement, non-refractory and the most aging, service life is shorter, in use easily because line load is excessive or outer
Portion's temperature is too high, and breaking out of fire of burning.Produce substantial amounts of flue dust and toxic gas pollution environment during its burning, human body is caused wound
Evil, brings hidden danger to the security of the lives and property of people.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of fireproof low-smoke halogen-free cable, and simple in construction is solid resistance to
With, there is higher abrasion resistance properties and outstanding fire protecting performance, good flame retardation effect, service life is long.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of fireproof low smoke and zero halogen
Cable, including: conductor be located at the protecting pipe outside conductor, described protecting pipe includes inner sheath, oversheath and is located at inner sheath
And the double steel layer between oversheath, the outer wall of described conductor is provided with flame retardant coating, and the outer wall of described flame retardant coating is provided with insulating barrier, described
It is provided with insulation fill stratum at gap between conductor and protecting pipe.
In a preferred embodiment of the present invention, the thickness of described pair of steel layer is 0.2-2.5cm.
In a preferred embodiment of the present invention, described insulation fill stratum is silica dioxide granule layer.
The invention has the beneficial effects as follows: fireproof low-smoke halogen-free cable of the present invention, simple in construction, durable, have relatively
High abrasion resistance properties and outstanding fire protecting performance, good flame retardation effect, service life is long.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in embodiment being described below required for make
Accompanying drawing be briefly described, it should be apparent that, below describe in accompanying drawing be only some embodiments of the present invention, for
From the point of view of those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other according to these accompanying drawings
Accompanying drawing, wherein:
Fig. 1 is the structural representation of fireproof low-smoke halogen-free cable one of the present invention preferred embodiment；
In accompanying drawing, the labelling of each parts is as follows: 1, inner sheath, and 2, oversheath, 3, double steel layer, 4, flame retardant coating, 5, conductor, 6, insulation
Layer, 7, insulation fill stratum.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described enforcement
Example is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, this area is common
All other embodiments that technical staff is obtained under not making creative work premise, broadly fall into the model of present invention protection
Enclose.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of fireproof low-smoke halogen-free cable, including: conductor 5 be located at the protecting pipe outside conductor 5, in described protecting pipe includes
Sheath 1, oversheath 2 and the double steel layer 3 being located between inner sheath 1 and oversheath 2, the outer wall of described conductor 5 is provided with flame retardant coating 4,
The outer wall of described flame retardant coating 4 is provided with insulating barrier 6, is provided with insulation fill stratum 7 at the gap between described conductor 5 and protecting pipe.
It addition, the thickness of described pair of steel layer 3 is 0.2-2.5cm.
It addition, described insulation fill stratum 7 is silica dioxide granule layer.
Fireproof low-smoke halogen-free cable of the present invention, simple in construction, durable, there is higher abrasion resistance properties with outstanding
Fire protecting performance, good flame retardation effect, service life is long.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this
Equivalent structure or equivalence flow process that bright description is made convert, or are directly or indirectly used in other relevant technology neck
Territory, is the most in like manner included in the scope of patent protection of the present invention.
