Abstract
The utility model relates to a high temperature-resistance electric wire with glass fibers, which is the electric wire composed of an insulating film, or a composite film, and the glass fibers which are knitted. The high temperature-resistance electric wire with glass fibers is composed of a conducting wire, an insulating layer and a protective layer. The external side of the metallic conducting wire is wound with the insulating film or the composite film and is additionally provided with the protective layer; the protective layer is knitted and coated by alkali-free glass fibers and are sintered; the insulating layer and the protective layer are tightly combined and coat the conducting wire, and the manufactured electric wire has the characteristics of high temperature resistance, corrosion resistance, high mechanical strength, stable insulating property and small external diameter dimension. The high temperature-resistance electric wire with glass fibers can be suitable for the occasions, such as the electrothermal electric apparatus, the special light fitting, the high temperature resistant electric motor, the lead wire of the instrument industry, etc.
Description
The utility model relates to and a kind ofly has high temperature resistantly, corrosion-resistant, and the electric wire that mechanical strength is high relates in particular to by insulation film or laminated film and the fiberglass braided electric wire of forming.
At present, electric heating appliance, extraordinary light fixture, the lead wire of heat resisting motor and instrument industry is had relatively high expectations to insulation property, and is bigger to anti-200 ℃ to 250 ℃ insulated electric conductor demand, to eliminate more existing porcelain tubes and high temperature resistant sleeve pipe.And the silicone rubber wire of generally selecting for use on the market has only 180 ℃ of temperature resistant grades, and mechanical strength is also relatively poor, needs fiberglass braided enhancing in addition, makes wire insulation thickness increase like this, and external diameter is bigger.250 ℃ of high temperature of another kind of tetrafluoroethylene electric wire ability, but price is more expensive, owing to adopt expressing technique, lead is eccentric easily on the other hand, insulation thickness is relatively also bigger.
The purpose of this utility model is to provide a kind of electric wire high temperature resistant, corrosion-resistant, that mechanical strength is high that has, and it can long-term work under 200 ℃ to 250 ℃ varying environment temperature.
The utility model is achieved in that a kind of glass fibre fire resistant electric wire; form by lead, insulating barrier and protective layer; wherein; insulating barrier and protective layer are coated on outside the plain conductor successively; lead outer wrapped one or more layers insulation film or laminated film earlier; add a protective layer again, protective layer is formed by the good resin of alkali-free glass fibre braiding and coated or dipping and insulating barrier compatibility.
Fig. 1 is a stranded conductor glass fibre fire resistant electric wire
Fig. 2 is a single cord glass fibre fire resistant electric wire
Among the figure, 1 is stranded conductor, and 2 is insulating barrier, and 3 is protective layer, and 4 is single cord.
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
A kind of glass fibre fire resistant electric wire; be made up of lead, insulating barrier and protective layer, the outer wrapped three strata tetrafluoroethene films of stranded conductor or single cord are as insulating barrier; insulating barrier is gone back matcoveredn outward, and protective layer is by alkali-free glass fibre braiding and coated or flood organic fluorine emulsion.Owing to adopt and the good emulsion of insulation film compatibility; protective layer and insulating barrier are combined closely behind the sintering; and be coated on the lead; the electric wire of making is high temperature resistant, corrosion-resistant, mechanical strength is high and good insulation preformance; outside dimension is little; cost is also lower, can use for a long time under 200 ℃ to 250 ℃ varying environment temperature.
Use for adapting to different high temperature resistant environment, insulating barrier can be selected the insulation film or the laminated film of different temperature resistant grades for use in the electric wire, but the coated material need be good with insulation film or laminated film compatibility, and protective layer behind the sintering and insulating barrier just can be combined closely like this.Select polyimide film for use as insulation film, then protective layer is alkali-free glass fibre braiding and coated and dipping polyimide resin.
The utility model has adopted the structure of insulation film or compound inslation Transposed wind; protective layer forms through sintering for braiding is coated with redoubling; make insulating barrier and the protective layer coated wire of combining closely; that the electric wire of making has is high temperature resistant, corrosion-resistant, mechanical strength is high; stable insulation, the characteristics that outside dimension is little are applicable to the occasions such as lead wire of electric heating appliance, extraordinary light fixture, heat resisting motor and instrument industry.
Claims (3)
1, a kind of glass fibre fire resistant electric wire; form by lead, insulating barrier, protective layer; wherein; insulating barrier and protective layer are coated on outside the plain conductor successively; it is characterized in that the outer wrapped insulating barrier of plain conductor is insulation film or laminated film; this insulation film or laminated film are one or more layers, and protective layer is formed by the good resin of alkali-free glass fibre braiding and coated or dipping and insulating barrier compatibility.
