Abstract
The invention discloses a soft high-fire-resistance cable which comprises a cable core. The cable core is formed by twisting multiple insulative cable cores. Binding layers are covered on the cable cores. Outer protection sleeves are covered on the outmost layers of cables in an extruded mode. A propene polymer (PP) rope is filled in gaps at the center of the twisted cable cores. Fire-proof cement is filled in gaps on the circumference of the twisted cable cores. The insulative cable cores are made of conductors and insulative layers made of ceramic silicon rubber materials and covered on the conductors in an extruded mode. The soft high-fire-resistance cable has the advantages of being low in smoke and toxics, halogen-free, capable of retarding inflames, fire resistant, good in flexibility and especially suitable for occasions which have high demands on fire resistance, wherein the occasions comprise high-rises, oil fields, power stations, electricity factories, mining hills, a chemistry industry, mining wells and subways.
Description
Technical field
The present invention relates to the electric wire field, specifically refer to a kind of flexible high flame resistant cable.
Background technology
At present, on market, popular fireproof cable mainly contains two kinds: a kind of is the structure that adopts fire-resistant wrapping tape and plastic insulation to combine, the great advantage of this structural cable is soft, applicable to mobile occasion, technique is easily manufactured, cost is lower, but this cable serviceability temperature grade is limited by insulating material serviceability temperature grade.And plastic insulation material easily burns, meeting evolution of heat during burning, cause temperature to increase, cause at last the fire-resistant wrapping tape carbonization, so, the not anti-mechanical oscillation of this cable, and in the situation that 750-850 ℃ of high-temperature flame can only keep safe operation 1.5 hours.
The another kind of copper core mineral insulation seamless copper pipe jacket structure that adopts, improved above-mentioned shortcoming, but due on making, it is subject to the metal tube length restriction as sheath, cable can't be accomplished needed any length, owing to adopting copper sheath, make cable very hard, be difficult to lay, the easy moisture absorption of simultaneous oxidation magnesium powder reduces insulation effect, so mineral insulated cable often because of the joint water inlet, causes that insulation resistance is defective.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of have low cigarette, low toxicity, Halogen, fire-retardant, fire-resistant and good flexible high flame resistant cable.
A kind of flexible high flame resistant cable of the present invention comprises cable core, and its cable core is tightened layer by stranded the forming of some eradication edge cores in the cable core outer cladding, extrudes oversheath at the cable outermost layer; Center gap place's filling pp rope that core is stranded, the anti-chamotte of surrounding gap filling that core is stranded.
Further improve, described insulated wire cores is by conductor and is extruded in the outer insulating barrier of conductor and consists of.
Further improve, described insulating barrier adopts the ceramic silastic material, and has fire-resistant and insulation property again.
Beneficial effect of the present invention:
Flexible high flame resistant cable of the present invention, to change traditional fire-resisting cable packing material, use a kind of fire prevention mud material of flexibility as filling, because this material has the characteristics such as fire-resistant, that the amount of being fuming is low, in the situation that breaking out of fire, can be in the situation that 950-1000 ℃ of high-temperature flame keep safe operation 3 hours, and the amount of being fuming is few during burning, and non-corrosiveness gas is overflowed.Greatly improved the use coefficient of safety of fire-resisting cable, for the relief fire has won certain hour, can not damage human body.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of flexible high flame resistant cable of the present invention comprises cable core, and its cable core is tightened layer 5 by stranded the forming of some eradication edge cores in the cable core outer cladding, extrudes oversheath 6 at the cable outermost layer; Center gap place's filling pp rope 3 that core is stranded, the anti-chamotte 4 of surrounding gap filling that core is stranded.Described insulated wire cores is to be made of conductor 1 and the insulating barrier 2 that is extruded in the outer employing ceramic silastic material of conductor 1.
The invention provides a kind of thinking and implementation method of flexible high flame resistant cable; concrete application approach is a lot; the above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
Claims (3)
1. a flexible high flame resistant cable, comprise cable core, and its cable core is tightened layer (5) by stranded the forming of some eradication edge cores in the cable core outer cladding, extrudes oversheath (6) at the cable outermost layer; It is characterized in that: center gap place's filling pp rope (3) that core is stranded, the anti-chamotte (4) of surrounding gap filling that core is stranded.
2. flexible high flame resistant cable according to claim 1, is characterized in that, described insulated wire cores is by conductor (1) and is extruded in outer insulating barrier (2) formation of conductor (1).
