Abstract

The utility model discloses a paper covered copper round wire comprising a copper round conductor, a first insulation paper layer tightly wrapping the copper round conductor, and a second insulation paper layer tightly wrapping the first insulation paper layer, and the diameter of the copper round conductor is 2.4mm. The paper covered copper round wire adopts two layers of insulation paper layers, so that the defective rate of the insulation paper layer is lowered, the insulating property is improved, and the safety performance of product is also accordingly improved.

Description

The paper bag copper round wire

Technical field

The utility model relates to a kind of paper bag copper round wire, particularly relates to the good paper bag copper round wire of a kind of insulation property.

Background technology

At present, winding wire generally adopts the wrapped one deck insulating paper layer of copper round wire, to solve the problem of insulation.

But the insulating paper layer structure of individual layer like this, having the insulating paper layer raw material is that the insulating paper layer that causes of substandard products is bad, and causes the relatively poor situation of insulation property, in practice, can equipment be affected greatly, and can cause production loss when serious.

The utility model content

The purpose of this utility model is: at the deficiencies in the prior art, provide a kind of paper bag copper round wire, to improve the insulation property of insulating paper layer.

The utility model provides a kind of paper bag copper round wire, and it comprises the copper coin conductor, closely wraps up first insulating paper layer of copper coin conductor, and second insulating paper layer of closely wrapping up first insulating paper layer, and the diameter of copper coin conductor is 2.4mm.

Further, in above-mentioned paper bag copper round wire, first insulating paper layer is different with the material of second insulating paper layer.

The utility model paper bag copper round wire uses the structure of double-deck insulating paper layer, can reduce the fraction defective of insulating paper layer, improves insulation property, makes the product safety performance also be improved.

Description of drawings

Just the utility model is described in further detail with enforcement below in conjunction with accompanying drawing:

Fig. 1 is the utility model paper bag copper round wire generalized section;

Fig. 2 is the technological process of production schematic diagram of the utility model paper bag copper round wire.

Embodiment

Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.

As shown in Figure 1, the utility model paper bag copper round wire comprises: copper coin conductor 1, closely wrap up first insulating paper layer 2 of copper coin conductor 1, and second insulating paper layer 3 of closely wrapping up first insulating paper layer 2.

The diameter of copper coin conductor 1 is 2.4mm.

First insulating paper layer 2 is different with the material of second insulating paper layer 3.First insulating paper layer 2 and second insulating paper layer 3 can be Nomex paper electricity paper, telephone paper, cable paper or 500KV transformer turn-to-turn insulation paper, and first insulating paper layer 2 are different with the material of second insulating paper layer 3.

As shown in Figure 2, the production technology of the utility model paper bag copper round wire may further comprise the steps: (1) bare wire enters first paper lapping machine via pay off rack, stabilizer and pinch roller, carries out the parcel of first insulating paper layer 2; (2) wrapped up after first insulating paper layer 2, entered second paper lapping machine, carried out the parcel of second insulating paper layer 3.

The above is all so that the utility model conveniently to be described, in the spiritual category that does not break away from the utility model creation, the various simple covert and modification that those skilled in the art did of being familiar with this technology still belongs to protection range of the present utility model.

Claims

1. a paper bag copper round wire is characterized in that, comprises the copper coin conductor, closely wraps up first insulating paper layer of copper coin conductor, and second insulating paper layer of closely wrapping up first insulating paper layer, and the diameter of copper coin conductor is 2.4mm.

2. a kind of paper bag copper round wire according to claim 1 is characterized in that first insulating paper layer is different with the material of second insulating paper layer.
