Abstract
The utility model discloses a fire-proof and high/low temperature resistant electric wire for a gas generator. A conductor of the electric wire is formed by twisting a plurality of nickel/silver/tin-plated soft copper monofilaments, wherein an insulating layer, a wrapping mica tape fire-proof layer and an extruded outer sheath are sequentially extruded outside the conductor. In the electric wire, the conductor formed by twisting the plurality of nickel/silver/tin-plated soft copper monofilaments is adopted, so that the aging and the catalysis of the copper conductor to the insulating layer can be effectively prevented and the service life of the insulating layer is ensured; meanwhile, nickel, silver or tin are plated on the surface of the copper filaments, so that the conductor is prevented from oxidization under the low and high temperature, accordingly, the safety and the reliability of the conductor during the use are enhanced.
Description
Technical field:
The utility model relates to a kind of fire-resistant, high-low temperature resistant fuel gas generation unit electricity consumption line, belongs to technical field of electric wires and cables.
Background technology:
The fuel gas generation unit is along with the raising requirement of equipment performance, and special installation is had requirements such as anti-high/low temperature, fire prevention, volume be little, in light weight.As fuel gas generation unit electrical installation, the instrument and meter connecting line wants that cube is little, electrical insulation capability good, fire-resistant, fire-retardant and can adapt to all kinds of high/low temperature environment, it is strong to bear overload capacity, and requirement has favorable mechanical physical property, electric property, have anti-high/low temperature, fire-resistant, fire-retardant, corrosion-resistant, weatherability, do not absorb water, characteristic such as coefficient of friction is low, high flame retardant and softness, safety guarantee is had relatively high expectations.But existing conventional electric wire can not satisfy this requirement.
Summary of the invention:
For overcoming the defective of prior art, combination properties such as the purpose of this utility model is to provide a kind of can possess anti-high/low temperature, fire-resistant, fire-retardant, corrosion-resistant, weatherability, do not absorb water, coefficient of friction is low, high flame retardant and softness can adapt to a kind of fuel gas generation unit electricity consumption line of multiple different operating environment.
The utility model technical solution problem adopts following technical scheme:
A kind of fire-resistant, high-low temperature resistant fuel gas generation unit electricity consumption line, described wire conductor be by many nickel plating, silver or stranded the forming of zinc-plated soft copper monofilament, conductor outward successively extruded insulation layer, wrapped mica tape flame retardant coating, extrude outer jacket.
The novel design feature of this practicality also is:
Described insulating barrier and outer jacket are to extrude with perfluoroethylene-propylene F46 or polytetrafluoroethylene F4.
Described conductor adopts regular lay configuration, and the twisted wire pitch is between 12-16 times; The sectional area of conductor is 0.35～10mm

Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model adopts the conductor of nickel plating, silver or the stranded formation of zinc-plated soft copper monofilament, can prevent the aging catalytic action of copper conductor to insulating barrier effectively, to guarantee the useful life of insulating barrier.Simultaneously, copper wire plating nickel on surface, silver or zinc-plated also have prevent this oxidation in high/low temperature condition under of conductor, fail safe and reliability in the increase use.
2, insulating material adopts perfluoroethylene-propylene F46 or polytetrafluoroethylene F4 material in the utility model, the anti-high/low warm nature with wide range, and it also has following performance:
(1) You Yi heat-resisting and resistance to low temperature can use in+250 ℃～-85 ℃ wide temperature ranges for a long time;
(2) splendid fire resistance, fire-retardant oxygen index is up to 90;
(3) good electrical insulation properties;
(4) have good resistance to water and moisture-proof;
(5) have excellent chemical stability and corrosion resistance;
(6) insulating material mechanical performance and excellent electrical properties can be extruded thin insulating, reduce cost, and reduce the cable volume;
(7) owing to be directly to extrude processing, do not need the equipment of extra preliminary treatment and reprocessing;
(8) can on the high temperature extrusion equipment, process, not need additional processing equipment (processing temperature is at 245 ℃ to 415 ℃);
(9) because be thermoplastic, the processing of can regenerating, and the heat ageing process is very slow, and very big recycling value is arranged, and meets environmental protection spirit.
