The tension high frequency enamelled winding wire of property.
Background technology
Along with the extensive use of large power supply wave filter and high frequency high voltage transformer, to high withstand voltage, high temperature resistant, cut greatly
The demand of the high frequency enamelled winding wire in face is increased, but the enameled wire twisting machine of domestic manufacture or import at present（Equipment）Produced
Go out maximum twisted wire sectional area and can only achieve 1.5mm2, and to 1.5mm2Industry demand above, can only lean on manufacturing enterprise secondary artificial
Processing is slapped together, and also needs to coat polyester film or polyimide film sizing outside, i.e., it cannot be guaranteed that the uniformity of product diameter,
It is also impossible to bring the quality guarantee of product, also brings the waste of a large amount of human and material resources.
The content of the invention
Problem to be solved in the utility model is to overcome the deficiencies in the prior art to be bonded there is provided one kind without dipping lacquer,
Simplify the tension high frequency enamelled winding wire with tack of manufacturing process.
The utility model solves its technical problem and takes following technical scheme to realize：
A kind of tension high frequency enamelled winding wire with tack, it is characterised in that：Protected including metal core, polyester-imide
Sheath, several metal cores are twisted into beam, in its one layer of polyester-imide protective layer of outer coating or several metal cores
The primary group of one group of composition enamel-covered wire is twisted into, the stranded bunchy of array enamel-covered wire primary group is protected in its outer one layer of polyester-imide of coating
Sheath, polyester-imide protective layer has heat-resisting, wear-resisting, refrigerant and scratch resistance performance；Described polyester-imide protective layer outer wrapping
There is polyamide imide, polyamide imide has excellent heat punching property, refrigerant, radiation resistance and excellent chemistry
Stability, the high property of softening and with good paint film mechanical strength, the outer surface of polyamide imide has heat molten type
Self-adhesion enamelled coating；Described metal core is by the stainless steel core positioned at center and the layers of copper group for coating this stainless steel wire core outer surface
Into.
Described metal core is externally provided with nylon fiber braiding layer, is easy to high-speed winding, improves production efficiency.
