Abstract
The utility model relates to a conductor field, and specially relates to a copper paper wrapped wire, comprising a copper core, a first paper wrapped layer, a second paper wrapped layer and a third paper wrapped layer. The first paper wrapped layer is wrapped outside the copper core; the second paper wrapped layer is wrapped outside the first paper wrapped layer; and the third paper wrapped layer is wrapped outside the second paper wrapped layer. According to the copper paper wrapped wire provided in the utility model, the wrapping gap is minimized, the raw material is saved by 3% to 4%, cost is reduced, and simultaneously, the insulation security of the copper paper wrapped wire is increased, and the insulation property of a wrapped transformer is substantially enhanced.
Description
Technical field
The utility model relates to the wire field, especially is a kind of copper paper covered wire.
Background technology
The paper of existing copper paper covered wire makes insulating barrier breakdown towards unified direction coiling easily, causes the transformer power consumption to increase, and can not satisfy the use needs, therefore needs a kind of insulating barrier be not easy breakdown paper covered wire, satisfies the needs of the equipment such as transformer.
Summary of the invention
The utility model purpose is to address the above problem, and provides a kind of insulating barrier to be not easy breakdown copper paper covered wire, is specifically realized by following technical scheme.
A kind of copper paper covered wire, this copper paper covered wire comprises copper core, the first paper bag layer, the second paper bag layer and the 3rd paper bag layer, described the first paper bag layer is wrapped outside the copper core, and described the second paper bag layer is wrapped outside the first paper bag layer, and described the 3rd paper bag layer is wrapped outside the second paper bag layer.
Described a kind of copper paper covered wire, it further designs and is that the winding direction of described the first paper bag layer is identical and opposite with the winding direction of the second paper bag layer with the winding direction of the 3rd paper bag layer.
The copper paper covered wire that the utility model provides makes raw material save between the 3%-4% so that the gap of coiling dwindles like this, has reduced cost, improves simultaneously the insulation safety of copper paper covered wire, so that the transformer insulated property of its coiling improves greatly.
Description of drawings
The schematic cross-section of the copper paper covered wire that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with Figure of description and specific embodiment the utility model is further specified.
This copper paper covered wire comprises that copper core 4, the first paper bag layer 1, the second paper bag layer 2 and the 3rd paper bag layer 3, the first paper bag layer 1 are wrapped outside the copper core, and the second paper bag layer is wrapped outside the first paper bag layer, and the 3rd paper bag layer is wrapped outside the second paper bag layer.The winding direction of the first paper bag layer is identical and opposite with the winding direction of the second paper bag layer with the winding direction of the 3rd paper bag layer.Namely when wrapped, the first, the 3rd paper bag layer is wrapped clockwise, and the second paper bag layer is wrapped counterclockwise; Perhaps the first, the 3rd paper bag layer is wrapped counterclockwise, and the second paper bag layer is wrapped clockwise.
The copper paper covered wire that the utility model provides makes raw material save between the 3%-4% so that the gap of coiling dwindles like this, has reduced cost, improves simultaneously the insulation safety of copper paper covered wire, so that the transformer insulated property of its coiling improves greatly.
