Description
Technical field
The utility model is related to a kind of high temperature resistant applied to high-power high-frequency filter inductor, high frequency high voltage transformer and resisted
Draw 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 wrap up 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 that there is provided a kind of high-temperature-resistant, tensile high frequency
Enamelled winding wire.
The utility model solves its technical problem and takes following technical scheme to realize：
A kind of high-temperature-resistant, tensile high frequency enamelled winding wire, it is characterised in that：Including metal core, polypropylene insulation layer, number
Metal core is twisted into beam described in root, and one group is twisted into its one layer polypropylene insulating barrier of outer coating or several metal cores
Constitute the primary group of enamel-covered wire, the stranded bunchy of array enamel-covered wire primary group, in its one layer polypropylene insulating barrier of outer coating；Described is poly-
Propylene insulating barrier is externally provided with inhibiting tape, and inhibiting tape is wrapped with layer of polyurethane, and the metal core is by Al-Mg alloy wire core and bag
Cover the layers of copper composition of this aluminum-magnesium alloy wire core outer surface.
Described inhibiting tape band is made up of the imperial adhesive tape of fluorine.
Described metal core is externally provided with nylon fiber braiding layer, is easy to high-speed winding, improves production efficiency.
The utility model has significant advantage and beneficial effect compared with prior art：High frequency performance is good, lower power consumption,
Save the energy；Production cost is reduced using compound core, with excellent resistance to elevated temperatures and preferable flexibility,
