Description

High-frequency current supply wire

Technical Field

The utility model relates to the technical field of electric wire, specifically a high frequency current supplies with electric wire.

Background

The high-frequency current is a current relative to a power frequency 50HZ alternating current. For example, the carrier current in the communicated signal is a high frequency current. In some cases, a frequency converter is used to change the motor speed, so that the power frequency current is changed into a relatively high frequency current, also called high frequency current. High frequency currents sometimes have significant radiation effects and even harm to humans. Of course, some of the low-power high-frequency currents are not harmful to the human body. An important characteristic of high frequency current is skin effect, such as a solid conductor, where current tends to run on its surface rather than the entire conductor.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a high frequency current supplies electric wire to solve the problem of high frequency current's radiation and skin effect among the prior art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a high frequency current supplies electric wire, includes first insulation overcoat, the internal surface of first insulation overcoat is equipped with the nanofiber layer, the inside on nanofiber layer is equipped with four little insulating layers, every the inside of little insulating layer all is equipped with flat conducting strip, flat conducting strip is the slice.

Preferably, a second insulating outer sleeve is arranged inside the nanofiber layer.

Preferably, a waterproof layer is arranged inside the second insulating outer sleeve, and a fireproof layer is arranged inside the waterproof layer.

Preferably, the fire-proof layer is internally provided with a coating layer, and the coating layer is internally filled with a filler.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the wire structure of the utility model is arranged into a flat conducting strip, and the flat conducting strip 9 is arranged into a sheet shape, so that the whole body is thinner, the skin effect can be reduced to the maximum extent, and the utilization rate of the wire structure is ensured;

2. the utility model discloses set up the nanofiber layer, the nanofiber layer plays shielding radiation's effect, can avoid the radiation of inside high frequency current to the injury of human body, sets up the insulating overcoat of one deck second again in the inside on nanofiber layer, can avoid inside high frequency current to lead to the nanofiber layer electrified, has guaranteed that the nanofiber layer is uncharged.
