Description
Technical field
The utility model be related to it is a kind of applied to high-power high-frequency filter inductor, high frequency high voltage transformer it is compound big
Sectional area high frequency enamelled winding wire.
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 reduce production cost there is provided one kind
Compound heavy in section product high frequency enamelled winding wire.
The utility model solves its technical problem and takes following technical scheme to realize：
A kind of compound heavy in section product high frequency enamelled winding wire, it is characterised in that：Protected including metal core, polyester-imide
Layer, several metal cores are twisted into beam, are twisted in its one layer of polyester-imide protective layer of outer coating or several metal cores
Synthesize the primary group of one group of composition enamel-covered wire, the stranded bunchy of array enamel-covered wire primary group, in its outer one layer of polyester-imide protection of coating
Layer, polyester-imide protective layer has heat-resisting, wear-resisting, refrigerant and scratch resistance performance；Described polyester-imide protective layer is wrapped with
Polyamide imide, polyamide imide has excellent heat punching property, refrigerant, radiation resistance and excellent chemistry steady
It is qualitative, the high property of softening and with good paint film mechanical strength；The metal core is by Al-Mg alloy wire core and coats this
The layers of copper composition of aluminum-magnesium alloy wire core outer surface.
Described metal core is externally provided with nylon fiber braiding layer, is easy to high-speed winding, improves production efficiency.
