A teflon insulated multi-strand low-loss winding wire comprising: an outer layer; the outer layer is provided with three layers, the three outer layers are respectively distributed according to the inner layer, the middle layer and the outer layer, and the thickness of each outer layer is 0.03mm soil and 0.003mm; stranded wires are arranged on the inner side of the outer layer; through being provided with skin and stranded wire, can guarantee insulating properties through the even skin of three-layer thickness, avoid the potential safety hazard that insulation breakdown brought, guarantee the roundness between the three-layer skin simultaneously to guarantee that outer inside has bigger wire winding space, guarantee the electrically conductive sectional area of stranded wire.

Description

Teflon insulation multi-strand low-loss winding wire

Technical Field

The utility model belongs to the technical field of insulated wire, more specifically say, in particular to insulating stranded low-loss winding wire of teflon.

Background

With the iterative development of transformer and inductance products, the requirements for winding wire products become more special correspondingly, and in order to meet the requirements of high voltage strength resistance, high temperature resistance, weather resistance and acid and alkali resistance of products, and the requirement that the products can work for a long time in different environments, a teflon wire is generally adopted, and the teflon wire is a wire formed by wrapping a metal conductor by using fluorine plastic as insulation.

The existing winding group has the following defects:

the most outer roundness of present winding group is relatively poor, occupies the inside great wire winding space of skin, leads to winding group loss to increase, further leads to components and parts programming rate to accelerate, is unfavorable for product life's extension.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides an insulating stranded low-loss winding wire of teflon to solve the present winding group that proposes in the above-mentioned background art and absolutely outer roundness relatively poor, occupy the inside great wire winding space of skin, lead to the winding group loss to increase, further lead to components and parts programming rate to accelerate, be unfavorable for the problem of product life's extension.

The utility model relates to a purpose and efficiency of insulating stranded low-loss winding wire of teflon is reached by following specific technological means:

a teflon insulated multi-strand low loss winding wire comprising: an outer layer; the outer layer is provided with three layers, the three layers of outer layers are respectively distributed according to the inner layer, the middle layer and the outer layer, the thickness of each layer of outer layer is 0.03mm soil and 0.003mm, the thickness of the three layers of outer layers is within 0.15mm, and the three layers of outer layers are concentrically arranged; the inner side of the outer layer is provided with a stranded wire.

Further, the stranded wire is sleeved on the inner side of the outer layer, and the stranded wire is manufactured by pressing and twisting the die.

Compared with the prior art, the utility model discloses following beneficial effect has:

through being provided with skin and stranded wire, extrude the three-layer skin in proper order through layering, through the outer indisputable fluorine dragon insulation thickness who uses of online test digital laser instrument and convex-concave appearance accurate monitoring, make the thickness between the three-layer skin even, can guarantee insulating properties through the even skin of three-layer thickness, avoid the potential safety hazard that insulation breakdown brought, guarantee the rounding degree between the three-layer skin simultaneously, thereby guarantee that outer inside has bigger wire winding space, guarantee the electrically conductive sectional area of stranded wire, thereby can further reduction high frequency alternating current loss, make components and parts intensification speed reduce in the use, be favorable to increase of service life, make the occupation space of components and parts product littleer simultaneously, it optimizes terminal product to change.
