Abstract
The invention discloses a low-smoke, zero-halogen, flame-retardant and environment-friendly electric wire, which comprises a stranded conductor in the middle of the electric wire and a polyvinyl chloride insulating layer wrapped outside the stranded conductor in an extruded manner. The low-smoke, zero-halogen, flame-retardant and environment-friendly electric wire has the advantages that the electric wire is low in smokiness, long in visual range, free of corrosive gas in combustion and high in heat resistance, and the long-term operation temperature of the conductor reaches 105-135 DEG C. In term of electrical performance, the electric wire is high in current carrying capacity which is improved by 20-40% as compared with that of a normal electric wire made of polyvinyl chloride, and is high in overload resistance, excellent in flame retardation, mechanically and physically stable, resistant to aging and high in corrosion resistance.
Description
?
Technical field
The present invention relates to a kind of low-smoke non-halogen flame-retardant and fixedly lay and use electric wire, be applicable to that rated voltage 450/750V and following has fire-retardant, low cigarette, Halogen, the building of environmental requirement, electrical equipment, switch equal power device system.
Background technology
Well-known pvc material has apparent in view advantage in processing characteristics, the ratio of performance to price; Thereby in electric wire, be widely used; But pvc material contains a large amount of halogens, and decomposition temperature is low, resistance to elevated temperatures is poor, can discharge a large amount of poisonous corrosive gas and dense smokes during burning; Cause " secondary disaster ", thereby the low cigarette of exploitation, Halogen, fire-retardant, environment-friendly type electric wire are the task of top priority.
Summary of the invention
It is good that technical problem to be solved by this invention provides a kind of electromechanical properties, simultaneously thermal endurance and the good low-smoke non-halogen flame-retardant environment-friendly electric wire of flame resistance.
A kind of low-smoke non-halogen flame-retardant environment-friendly electric wire comprises the stranded conductor that electric wire is middle and is extruded in the outer polyvinyl chloride insulation layer of stranded conductor.
Said conductor material is an oxygen-free copper.
Beneficial effect of the present invention:
The present invention has low smokiness, and visual range is long, does not produce corrosive gas during burning, good heat resistance, and conductor long-term work temperature reaches 105～135 ℃ characteristics.Not only current-carrying (promotes 20～40% with respect to common polyvinyl chloride material electric wire) greatly aspect electrical property, and anti-overload ability is strong, has excellent flame-retardant, and mechanical-physical is stable, anti-aging, corrosion resistance and good.
Description of drawings
Fig. 1 is a cross-sectional view of the present invention.
Embodiment:
Below in conjunction with accompanying drawing the present invention is described further.
Like Fig. 1, a kind of low-smoke non-halogen flame-retardant environment-friendly electric wire of the present invention comprises the stranded conductor 1 that electric wire is middle and is extruded in the polyvinyl chloride insulation layer 2 outside the stranded conductor 1.Stranded conductor 1 selects high-quality oxygen-free copper to be drawn into stranded forming behind the molded lines as conductor material; Insulating barrier is selected low-smoke halide-free fireproof composite polyolefine material, is extruded on the conductor 1 after cross-linking radiation forms insulation.
Method for fabricating insulating layer: insulation adopts plsitive mold to extrude low-smoke halide-free fireproof composite polyolefine material, insulator consolidation, rounding, smooth surface; After carry out crosslinkedly through electron accelerator irradiation, make the insulation temperature resistant grade reach 125 ℃, specific insulation>=1 * 10 of under 1kV, 20 ℃ of conditions, insulating
15Ω m.
Cable through resistance, voltage, resistance, ozone, heat resistance, low temperature resistance, flame retardancy, heat shrinkage, wear-resisting, cross-linking test smoke density (minimum transmittance) ≥ 80%, PH value ≥ 4.3, the conductivity (μS / mm) ≤ 10, smoke toxicity comply with GB / T? 20285? ZA
2 level.
The present invention satisfies the electric property, mechanical performance, heat resistance of rated voltage 450/750V and following electric wire and the requirement of fire resistance, poisonous gas security performance under the fire condition.
The concrete application approach of the present invention is a lot, and the above only is a preferred implementation 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 regarded as protection scope of the present invention.
