Description
Technical field
It the utility model is related to three-layer insulated safety wire of new high life.
Background technology
At present, electric electric wire is mostly common insulated electric conductor in household or industrial electrical equipment, the diameter of its conducting wire monomer
Generally in more than 2mm, its hardness is significantly increased after stranded conductor monomer is twisted, it is not easy to bends, difficulty is brought to laying-out；
And in order to improve the class of insulation of electrical appliance equipment, it is often interim on common insulated electric conductor to cover PE heat-shrinkable tubes, so
Complex procedures, and wearability due to PE heat-shrinkable tubes and corrosion resistance are poor, cause the insulated electric conductor wearability and corrosion resistance
It is poor, short life, and be easily deformed and leak electricity.
In existing fire resistant electric wire product, use environment is the most severe, engineering reliability requirement is highest surely belongs to use
In the fire resistant electric wire of aerospace field.Used cross-linked polrvinyl chloride insulated electric conductor was once adopted in the past, its temperature resistant grade is only
There are 105 DEG C, although the temperature resistant grade of silicone rubber insulated wires, up to 200 DEG C, the tensile strength of silicone rubber insulation layer is very low,
It is difficult to thin layer insulated wire is made, is insufficient for the technology needs of higher and higher modern aerospace.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of three-layer insulated safety wire of new high life,
The three-layer insulated safety wire includes wire stylet, inner insulating layer, middle insulating layer and external insulation layer from the inside to the outside, and wire stylet is by having
Conductive metal material is made, the inner insulating layer is prepared by polyolefine material containing cross-linking radiation, middle insulating layer by
Cross-linking radiation polyolefine material containing halogen-free flame retardants is prepared, external insulation layer is by the cross-linking radiation polyene containing antiager
Hydrocarbon material is prepared, and inner insulating layer, middle insulating layer and external insulation layer are obtained by three-layer co-extruded extrusion.
The middle insulating layer, inner insulating layer, the ratio between the thickness of external insulation layer are 1：0.01-0.2：0.1-0.3.
The wire stylet is the copper wire of 0.12~0.15mm of diameter.
The three-layer insulated safety wire of new high life of the utility model is after high-energy electron beam irradiation, the strand of material
Structure is from linearly becoming three-dimensional netted molecular structure, and temperature grade brings up to 125 DEG C from original 70 DEG C, than equivalent specifications
The current-carrying capacity of electric wire will improve about 30%.Since the temperature resistant grade of cross-linking radiation polyolefine material is high, aging temperature is high, when short-circuit
The maximum temperature of permission is also high, so can more bear to overload than general electric wire.
The three-layer insulated safety wire of new high life of the utility model has passed through the CE product safety certifications of European Union, product
And used material passed European Union ROSH instructions, be green product, not plasticizer-containing and harmful heavy metal, product
It is more environmentally friendly, safer.
Traditional PVC insulated wire and the oxygen index (OI) of flame retardant type electric wire and low smoke no-halogen wire material only have 28~
32, and the oxygen index (OI) of the three-layer insulated safety wire of new high life of the utility model has reached more than 35, fire resistance is more excellent,
It can more prevent from unexpectedly occurring, and avoid propagation burning things which may cause a fire disaster because of its good high flame retardant when fire occurs and made for user
Into bigger.
The three-layer insulated safety wire of new high life of the utility model according to test method specified in GB/T11026,
Surpass 70 years in 125 DEG C of operating temperature ratings using the service life that Arrhenius (Arrhenius) curve is derived, if pressing
When operating temperature ratings are 90 DEG C, then service life exceeded 100 years, the electric wire of traditional handicraft is general when pressing 70 DEG C of operating temperatures
The time limit is lower if by 90 DEG C at 30 years or so.
The above-mentioned of the application and other features, aspect and advantage is more readily understood with reference to described further below.
