100 twists/m, composite fibre line is made；
S2: it after epoxy resin, polyurethane resin and curing agent are mixed, is stirred with the revolving speed room temperature of 200-300r/min
30-60s is mixed, silicon nitride, dimethylbenzene, surfactant is then added, keeps revolving speed is constant to continue to stir 3-5min, is mixed
Liquid；

For a long time, traditional overhead power transmission conducting wire mainly uses steel-cored aluminium strand, in order to improve antiseptic property, develops
Steel-aluminum wire etc..In order to improve intensity, steel core aluminum alloy stranded wire, all aluminium alloy twisted wire are developed, aluminium packet steel-core-aluminium closes
Golden twisted wire etc. develops various heat-resistant aluminum alloy wires to improve the heat resistance and transmission capacity of conducting wire.In last century 90
In the age, people attempt to replace metal material with carbon fibre composite to make the core material of conducting wire, and achieve certain achievement,
Several composite material synthesis core conducting wires are developed.It is as an improvement type earliest in terms of NEW TYPE OF COMPOSITE synthesizes core conducting wire
Low-sag conductor and propose；It has arrived in the 1990s, Japanese scholars research replaces steel core with carbon fiber core, has had developed one
Kind advanced composite material (ACM) synthesizes core conducting wire, i.e. carbon fiber core aluminium stranded wire.This conducting wire has identical with common steel-cored aluminium strand
Outer diameter and intensity, do not need special equipment and method in Poling Construction.In this conducting wire, common steel-cored aluminium strand
Steel core is replaced by the composite material core wire made of carbon fiber, this is that one kind is light-weight, linear expansion coefficient is small, has good relax
Spend the epoch-making novel conductive wire of characteristic.Therefore, it can be seen why carbon fiber core can substitute from the development course of conducting wire
Steel core is primarily due to carbon fiber core with light, the low advantage of arc sag.Novel overhead power transmission road is being studied with leading in various countries
Line, to replace traditional steel-cored aluminium strand, carbon fiber composite core wire tensile strength is big, arc sag is low, can increase shaft tower span,
Shaft tower height is reduced, thus engineering cost can be reduced.This conducting wire running temperature is high, effective passage section is big, is not only able to achieve
Current-carrying capacity multiplication, and can reduce wire ice cover；In addition, carbon-fibre wire is composite core, it is light weight, corrosion-resistant,
It can reduce wire quality, the magnetic loss for reducing route, the line applications suitable for heavy corrosion area.
In turn, those skilled in the art is devoted for years in research carbon fiber composite core wire intensity is high, arc sag is small, resistance to height
Temperature etc., but the defect of seldom concern carbon fiber itself influences composite core bring.Such as: Chen Hu Yuan Ming Niu Ziqiang carbon fiber
Tie up the research of compound core conducting wire mechanical property [J] engineering technology .2016,11,20:275, pass through the increasing using carbon fiber as conducting wire
Strong material is prepared in conjunction with the composite conductor core that modern pultrusion technique produces, and in the twisted aluminium alloy conductor in outside
Aerial condutor out.Development results: relative to steel reinforced soft aluminum strand, carbon fiber composite core wire arc sag at 80 DEG C or so is turned
Point, when before 80 DEG C, the arc sag of carbon fiber composite core wire increases larger, the arc sag of carbon fiber composite core wire after 80 DEG C
Incrementss are smaller, tend to balance.And the temperature of steel reinforced soft aluminum strand-arc sag incrementss amplitude of variation is larger, relative to carbon fiber
The arc sag of compound core conducting wire is big.For another example, the patent document of Publication No. CN103413629A discloses a kind of transmission line of electricity carbon fiber
It ties up manufacturing method of composite core and improves the mechanical performance of composite core to a certain extent only by the improvement of technique, only will
Carbon fiber and glass fibre are simply compound, not can effectively solve the technical problem of carbon fiber easy fracture, and service life is short.Carbon fiber
The conventional production process for tieing up composite core is carbon fiber, glass fibre and epoxy resin to be combined, and the brittleness of three is big,
So the brittleness of composite core is also big, easy fracture.Those skilled in the art thinks, this is because the characteristic of raw material itself determines
, and manufacturing cost is low, just keeps in mind and has been broken just update.But each maintenance and replacement, it is brought to operator heavy
Workload.Present inventor is in order to reduce the workload of operator, also for the Electrical Safety for guaranteeing user, for many years with great concentration
The raw material and preparation method for studying carbon fiber complex core, from raw material, by carbon fiber, glass fibre and polyester fiber with it is organic
Object, inorganic matter combine, and each component synergistic effect has complementary advantages, composite core is made to have preferable toughness, can occur after stress certain
Deformation, avoid the case where being directly broken, improve tension, the compressive property of composite core, the service life of extension lead, reduction is led
The frequency of line maintenance and replacement guarantees transmission line safety operation.
The beneficial effects of the present invention are:
Carbon fiber is high intensity, the new fiber materials of high modulus fibre of a kind of phosphorus content 95% or more, is had axial strong
Degree and modulus are high, and density is low, higher than performance, no creep, and superhigh temperature resistant under non-oxidizing atmosphere, fatigue durability is good, thermal expansion coefficient
It is small, the advantages that good corrosion resistance.Although intensity is high but carbon fiber is fragile material, stress it is excessive will not deformation occurs but it is straight
Fracture is connect, so can not be repaired substantially after damage, can only be replaced.Glassfiber insulation is good, heat resistance is strong, corrosion resistance is good,
High mechanical strength, but property is crisp, wearability is poor.Therefore it is compound with polyester fiber, the wrinkle resistance and conformality of polyester fiber are fine,
Intensity with higher and elastic recovery capability, it is strong it is durable, have excellent crease resistance, elasticity and dimensional stability, three's system
It at composite fibre line, is used in conjunction with, improves the mechanical strength and toughness of composite core.And the very high silicon nitride of intensity is added, have
Excellent resistance to heat shocks energy, antioxygenic property, abrasion resistance properties, corrosion resisting property, improve the mechanical performance of material.Polyurethane
Ethyl ester resin and epoxy resin cooperate, and the elasticity of reinforcing material improves the brittleness of epoxy resin, shape occurs after making material stress
Become, rather than is directly broken.Curing agent 703,704 or 781 is used cooperatively with epoxy resin, surfactant polyoxyethylene nonyl phenyl second
Alkene ether phosphate or laurel alcohol ether phosphate potassium reinforced epoxy, polyurethane resin and carbon fiber, glass fibre
With the compatibility of polyester fiber, the stability of maintenance system.
Electric power line carbon fiber compound core conducting wire plug of the present invention shows good comprehensive performance: mandrel surface circle
It is whole, bright and clean, smooth, color is consistent, zero defect, tensile strength exists in 2663MPa or more, elasticity modulus 130GPa or more, plug
With 1 circle of winding speed winding no more than 3r/min on the cylinder of 55D diameter, plug does not crack, not broken, radial pressure resistance performance
The pressure for being not less than 30KN is born in test, and end does not crack and peels.360 ° of tests are reversed, surface layer is not cracked, and after torsion
Tensile strength reaches 2511MPa or more.
