" the aircraft wire cable testing methods of GJB 17 " technical requirement.Because enamelled stranded-wire is used for high-frequency and high-voltage inductor, in reality
The impact that border will be subjected to high current caused by moment in working and high heat is brought, this is that current domestic any product not yet relates to
The field of foot.
The heavy in section product high frequency enamelled winding wire patent of our company early stage, can not meet the requirement of user, user early stage
Import need to be relied on for a long time using the said goods.
Thus my company determines project verification, develops a kind of application type high-frequency and high-voltage enamel-cover that disclosure satisfy that and surmount above-mentioned requirements
Twisted wire.
The content of the invention
In view of the development of existing market and the lifting of technical requirements, the utility model is in utility model patent
（ZL201220246142.2）On the basis of technology, from the selection of enamelled wire insulated paint, increase component, carried out to production technology
Improve and innovate again, there is provided accumulate enamelled stranded-wire in a kind of TF application types high-frequency and high-voltage heavy in section.
The high-frequency and high-voltage enamelled stranded-wire, its sectional area are 1.5mm2~35 mm2, finished product is pressure-resistant ＞ 8000V, can be for a long time in ring
Border temperature works under the conditions of being -40 ~+150 DEG C, and with salt spray resistance and hot and humid environment under acid and alkali-resistance, adaptation marine climate
In corrosion resistant feature.
To achieve the above object, used technical scheme is the utility model patent：A kind of TF application types high-frequency and high-voltage
Accumulate enamelled stranded-wire in heavy in section, it is characterised in that：86 or the primary line group of the twisted bunchy composition of 95 enamel-cover single lines, 7 groups of primary lines
The twisted bunchy of group forms enamel-covered wire group, and one layer of polytetrafluorethylecoatings coatings are coated in enamel-covered wire group outer surface；
The enamel-cover single line includes the copper conductors of Φ 0.25, polyurethane paint insulating barrier, nylon composite bed, and the bronze medals of Φ 0.25 are led
12 strata urethane varnished insulation layers of external coating, coat 2 layers of nylon composite bed outside 12 strata urethane varnished insulation layers；
The heavy in section product enamelled stranded-wire finished product that 86 enamel-cover single lines are formed, single enamel-covered wire sum is 602, and sectional area is
29.55mm2；The heavy in section product enamelled stranded-wire finished product that 95 enamel-cover single lines are formed, single enamel-covered wire sum is 665, sectional area
For 32.5mm2 ；
The specific arrangement architecture of 7 groups of primary line groups is：Outside middle one group of primary line group, 6 groups of primary line groups are arranged.
The beneficial effects of the utility model are：
1. single line is developed again with polyurethane paint used in pair enamelled stranded-wire, selected after repetition test is proved
Single line insulating barrier with paint be base material for 95~96% precious 155 grades of polyurethane paints of Taiwan good fortune, add 4-5% closing isocyanic acid
Ester（blocked isocyanates）Stir tune and uniformly form polyurethane paint, as enamel-cover single line paint special.The purpose so done has
2 points below, first, good fortune 155 grades of polyurethane paints of treasured in Taiwan, under coating layer thickness same case, every electrical performance indexes are superior to it
The insulated paint of its brand, second, with the increase of twisted wire number of share of stock or sectional area, it can be produced when polyurethane enamelled wire directly welds a large amount of black
Color residue deposit, it is extremely difficult to clear up, after adding 4-5% blocked isocyanate components, both improved enamelled coating adhesive force, and made residue again
More than 30% is reduced, and remaining residue is also easily cleared up.
2. changing single line coating process, former single line coating layer thickness is kept, 12 layers of coating are changed to by 8 layers of coating of traditional handicraft,
Furnace temperature of the enamel-covered wire in baking process is adjusted, center furnace temperature 375 is downgraded by 390 DEG C original of center furnace temperature, 430 DEG C of outlet
DEG C, outlet 412 DEG C, take-up speed by routine 90 ms/min increase to 92 ms/min, make coating more uniform, it is ensured that enamel-cover
The stabilization of every electrical performance indexes of single line and lifting.
2 layers of nylon composite bed are applied 3. applying the enamel-cover single line after carrying out according to new technology and increasing, to reduce during follow-up process
Coefficient of friction, reach further improve pressure voltage effect.
Example：The single enamel-covered wires of the mm of 1UEW 0.25, external diameter is Φ after Φ 0.25mm bare copper wires are applied into 12 layers of insulated paint
0.284mm, it is Φ 0.287mm to add external diameter after applying 2 layers of nylon composite bed, and complement outside diameter meets JISC3202 1UEW external diameter requirements,
Enamel-cover single line pressure voltage by standard >=2400V be promoted to after process modification >=5000V.Enamelled stranded-wire integral surface coating thickness
For 0.3mm polytetrafluorethylecoatings coatings, enamelled stranded-wire totality pressure voltage is promoted to ＞ 8000V, has been provided simultaneously with acid and alkali-resistance, corrosion resistant
Lose, suitable for the characteristic of marine climate environment.
4. the strand of pair enamelled stranded-wire is improved to, lay, the primary group of traditional handicraft is twisted i.e. dextrorotation clockwise, secondary
Twisted some groups are twisted i.e. left-handed counterclockwise.Determine that twice stranding twists after overtesting to be changed to clockwise to from twisted counterclockwise
Twisted, i.e., primary group and post forming are twisted and are twisted for same rotation direction, and so change reduces the entire outer diameter of twisted wire finished product
10%, while the larger coefficient of resilience caused by former stranded mode is reduced, the twisted wire body after the completion of making keeps original flexibility,
Play compression stroke and be easy to the good result of user's following process.
5 the utility model, from the selection of enamelled wire insulated paint, increase component compared with original technology, equal to production technology
Improve and innovate again, increased TF coat thickness.Enamelled stranded-wire maximum secting area is by 20mm2It is promoted to 35mm2, it is pressure-resistant
＞ 8KV are promoted to by >=5KV, tests through third-party institution's detection and client, in solution water and under room temperature environmental condition, reaches
Do not puncture to 10kv, possess continuously worked under -40 DEG C~150 DEG C adverse circumstances, acid-alkali-corrosive-resisting, suitable for marine climate
The characteristic of environment, save the energy more than 25%.The utility model solves the problem that the said goods relied on import for a long time in the past, fills out
Domestic technique and the blank of product are mended.The project is applied to that technology is more high-end, more advanced high frequency high voltage electronic product, for enterprise
The product of industry opens a broader, technical field covering more fully frontier, has been established for science and technology in enterprise development solid
Basis, while also create bigger Social benefit and economic benefit for enterprise and client.
