Abstract
The utility model provides a copper-core fluoro-plastic insulation high-temperature-resisting cable including conductor wires. The conductor wires are formed by wrapping polyfluorinared ethylene propylene insulation layers on stranded conductor wires. Anti-flaming rock wool ropes are filled between the conductor wires. A double-layer GSG rock wool tape with a thickness of 0.14mm and a double-layer highly anti-flaming glass fiber woven belt are adopted for wrapping the conductor wires and the anti-flaming rock wool ropes successively, so that a double-layer protection structure is formed. The whole cable is wrapped with an anti-flaming PVC sheath. The copper-core fluoro-plastic insulation high-temperature-resisting cable provided by the utility model has good electrical properties and mechanical physical properties and meets using requirements. The copper-core fluoro-plastic insulation high-temperature-resisting cable is anti-flaming, halogen-free, low-smoke, low-toxic, and does not contain eight harmful heavy metal elements such as lead, cadmium and the like and matters causing environmental pollution or damages such as phosphorus and the like.
Description
Technical field
The utility model relates to cable cable field, specifically relates to a kind of copper core insulating high-temperature-resistant fluoroplastic cable.
Background technology
Cable is in use because itself generates heat higher, need to guarantee heat-resisting quantity and the anti-flammability of cable, the outer fluororesin parcels that adopt of current high temperature resistant multicore cable more, the middle pp of employing rope is filled, the outside nonwoven fabrics twining package tape that adopts, wrapping rounding, high temperature resistant and the fire-retardant degree of this cable is not high, can not meet actual needs, and cable pernicious gas be can volatilize in use, environment and air pollution caused.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes above-mentioned technology, and the copper core insulating high-temperature-resistant fluoroplastic cable that a kind of fire-retardant degree is high is provided, and environmentally safe.
For achieving the above object; the technical scheme that the utility model adopts is: copper core insulating high-temperature-resistant fluoroplastic cable; comprise conductor lines; described conductor lines is to be wrapped with one deck perfluoroethylene-propylene insulating barrier at the stranded conductor line to form; be filled with fire-retardant mineral wool rope between the multiply conductor lines; conductor lines and fire-retardant mineral wool rope adopt the GSG synthetic mica tape of double-deck 0.14mm thickness and the high flame retardant glass braid band parcel of double-deck 0.17mm thickness outward successively; form double-layered protecting structure, whole cable outer wrap has flame-proof PVC sheath.
The beneficial effects of the utility model are:
1) product has good electric property and mechanical and physical performance, meets instructions for use.
2) eight kinds of harmful heavy metals such as fire-retardant, Halogen, low cigarette, low toxicity, not leaded, cadmium, the material to environment or destruction such as without phosphorus.
3) nonflammable during breaking out of fire, and burning to discharge gas little to the harm of personnel and peripheral facilities.
4) there is very high security feature, can not work the mischief to environment during simultaneously in use with waste treatment.
The accompanying drawing explanation
Fig. 1 is structural section figure of the present utility model.
Embodiment
Specifically describe the utility model in detail below in conjunction with accompanying drawing;
As shown in Figure 1; copper core insulating high-temperature-resistant fluoroplastic cable; comprise conductor lines; described conductor lines is to be wrapped with one deck perfluoroethylene-propylene insulating barrier 2 at stranded conductor line 1 to form; be filled with fire-retardant mineral wool rope 3 between the multiply conductor lines; the outer GSG synthetic mica tape 4 of double-deck 0.14mm thickness and high flame retardant glass braid band 5 parcels of double-deck 0.17mm thickness of adopting successively of conductor lines and fire-retardant mineral wool rope 3, form double-layered protecting structure, and whole cable outer wrap has flame-proof PVC sheath 6.
Cable selects perfluoroethylene-propylene as insulating material, has the mechanical performance higher than general fluororesin, has resistance to chemical attack, high-and low-temperature resistance, UV resistant and nuclear radiation.It is applicable to the occasion of some condition harshnesses.Can replace stainless steel, titanium alloy, monel metal.Can under-40～-130 temperature difference conditions, use for a long time.Extruding of this Insulation Material must be produced with special special-purpose plastic extruding machine, temperature reaches 300～400 degree, pass through material modification, under the prerequisite that does not reduce properties of materials, increase the consumption of certain compounding ingredient, reduce the extrusion temperature of material, use 90 plastic extruding machines, common screw is produced, and adds resistant to elevated temperatures special cotton thread and dyed yarn band simultaneously between cable conductor and insulating barrier, to distinguish the insulation phase sequence.
Gasket for packing adopts medium-alkali glass fibre, should meet the gasket for packing raw yarn, adopts fiber size for reinforcemeent, and its content is 0.5-2.0%.It is high temperature resistant, flame resistant, filling flexibility are good.Reaching the effect of filling rounding, stand higher working temperature.The stranding band adopts the GSG synthetic mica tape of double-deck 0.14mm thickness and the high flame retardant glass braid band of double-deck 0.17mm thickness, forms the double shielding effect, except the insulated wire cores laying up diameter, tightens effect, also plays good fire-resisting protection effect.
Cable sheath material is selected 105 ℃ of polyvinyl chloride flame-retardant sheath materials, and the temperature of sheath material is consistent with the working temperature of fluoroplastics under normal circumstances, and according to GB/T12706-2008, standard code extrudes thicker oversheath, to meet resistant to elevated temperatures instructions for use.
