Abstract
The utility model provides a environmental protection type fireproof flexible cable, comprising a cable core, a filling layer, a cabling fiber glass belt and an outer sheath, wherein the cable core includes a plurality of the conductors, the fireproof layers and the insulation layers stranding together; a glass braid is arrnaged between the cabling fiber glass belt and the outer sheath, and a layer of copper wire braid is arranged inside the glass braid; also a fiber glass fiber layer is arranged on an exine of the insulation layer of the cable core; the insulation layer is the inflaming retarding low-smoke polyolefin insulation layer; the outer sheath is the inflaming retarding low-smoke polyolefin restrictive coating. The utility model effectively satisfies fireproof and fire-resistant requirements, meanwhile effectively reduces causticity of decomposed combustion products and generated smog when the cable is burning.
Description
Technical field
The utility model relates to a kind of cable, relates generally to a kind of pro-environment fire prevention flexible cable.
Background technology
In the prior art, the environment-friendly type electric wire has become the main product of all cable kinds, and particularly abroad in the developed country, as states such as Europe, the United States, days, government forbids to use or the non-environment-friendly cable of import.Because contain a large amount of halogens in the common fire proofing, in burning, can produce a large amount of smog and poisonous corrosive hydrogen halides gas, human body there is great harm.And halogen-free flameproof mainly is chosen in and realizes in the polyolefin, thus low-smoke halogen-free cable will be after main development tendency.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technological deficiency, and a kind of pro-environment fire prevention flexible cable is provided.The utility model can satisfy effectively that cable can be prevented fires, fire-resistant requirement, the corrosivity of the combustion product that decomposes in the time of effectively reducing cable fire simultaneously and the amount of smoke of generation
For achieving the above object, the technical solution adopted in the utility model is:
Pro-environment fire prevention flexible cable comprises cable core, packed layer, stranding glass fiber tape and outer jacket from inside to outside successively; Cable core comprises conductor, fireprotection layer and the insulating barrier that strands forms; Be provided with glass braid between stranding glass fiber tape and the outer jacket, also be provided with one deck copper wire braid in the glass braid, it is characterized in that: the insulating barrier outer wall of described cable core also is provided with the glass fiber layer; Described insulating barrier is the flame-retardant low-smoke halogen-free polyolefin insulation layer; Described outer jacket is a flame-retardant low-smoke halogen-free polyolefin jacket layer.
Described fireprotection layer is mica tape or glass fiber tape.
Advantage of the present utility model is:
1, conductor adopts strands to form, and makes cable softness very, can be used for roving place.Outside insulating barrier, designed glass braid, so not only can improve cable insulation property, tensile strength, also can strengthen the fireproofing of cable performance and strengthen its chemical stability and thermal endurance simultaneously.If this product when suffering flame combustion, can not burn for about 900 ℃ in temperature, and stop flame to pass, secluding air, the protection cable insulation is avoided burning, and the amount of smoke that produces during burning, halogen gas are all seldom, also meet environmental protection requirement.Between conductor and insulation, design fireprotection layer, strengthened its fire protecting performance.
2, insulating barrier and outer jacket all are to adopt the flame-retardant low-smoke halogen-free polyolefin layer, make cable when fire burns, can not discharge toxic gas as HCL and a large amount of smog.Designed glass braid outside insulating barrier, insulation property, the tensile strength that not only can improve cable also can strengthen its fire protecting performance.
Description of drawings:
Fig. 1 is the utility model structural representation.
Mark among the figure: 1 is conductor, and 2 is fireprotection layer, and 3 is insulating barrier, and 4 is the glass fiber layer, and 5 is packed layer, and 6 is the stranding glass fiber tape, and 7 is glass braid, and 8 is the copper wire braid, and 9 is glass braid, and 10 is outer jacket.
Embodiment
Pro-environment fire prevention flexible cable comprises cable core, packed layer 5, stranding glass fiber tape 6 and outer jacket 10 from inside to outside successively; Cable core comprises conductor 1, fireprotection layer 2 and the insulating barrier 3 that strands forms; Fireprotection layer 2 is mica tape or glass fiber tape, be provided with glass braid 7,9 between stranding glass fiber tape 6 and the outer jacket 10, also be provided with one deck copper wire braid 8 in the glass braid 7,9, it is characterized in that: insulating barrier 3 outer walls of described cable core also are provided with glass fiber layer 4; Described insulating barrier 3 is the flame-retardant low-smoke halogen-free polyolefin insulation layer; Described outer jacket 10 is a flame-retardant low-smoke halogen-free polyolefin jacket layer.
In the utility model, conductor adopts strands to form, and makes cable softness very, can be used for roving place.Outside insulating barrier, designed glass braid, so not only can improve cable insulation property, tensile strength, also can strengthen the fireproofing of cable performance and strengthen its chemical stability and thermal endurance simultaneously.If this product when suffering flame combustion, can not burn for about 900 ℃ in temperature, and stop flame to pass, secluding air, the protection cable insulation is avoided burning, and the amount of smoke that produces during burning, halogen gas are all seldom, also meet environmental protection requirement.Between conductor and insulation, design fireprotection layer, strengthened its fire protecting performance.Insulating barrier and outer jacket all are to adopt the flame-retardant low-smoke halogen-free polyolefin layer, make cable when fire burns, can not discharge toxic gas as HCL and a large amount of smog.Designed glass braid outside insulating barrier, insulation property, the tensile strength that not only can improve cable also can strengthen its fire protecting performance.
