Abstract

The utility model relates to the field of cables and specifically relates to a low-dielectric-loss cable. The cable includes an external protective sleeve and insulating wire cores. A cellular empty cavity is arranged in the external protective sleeve. The insulating wire cores are arranged in the empty cavity with gaps in between. The low-dielectric-loss cable adopts the cellular empty cavity to support the internal insulating wire cores and to reduce a contact area of the insulating wire cores and the empty cavity. The cable reduces dielectric loss through use of a comparatively low dielectric constant of the air so that the cable is a low-dielectric-loss cable which is wide in purpose.

Description

The low-dielectric loss cable

Technical field

The utility model relates to field of cables, specifically a kind of low-dielectric loss cable.

Background technology

Cable is to be made by conductor outsourcing insulation and the protective layer of one or more mutually insulated; by electric power and/or information from a wire that is transferred to another place; existing cable is to adopt insulating material that conductor is fixed on to inside; but there is dielectric loss in insulating material, dielectric loss means one of index of insulating material (as the insulation oil plant) quality.Insulating material (as transformer oil) caused energy loss under the voltage effect.Dielectric loss is less, and better, insulation property also better, therefore are necessary to reduce as much as possible in the design of cable dielectric loss to the quality of insulating material.

Summary of the invention

Key in herein summary of the invention and describe paragraph.Primary and foremost purpose of the present utility model is to provide a kind of cable of low-dielectric loss, and concrete scheme of the present utility model is as follows for achieving the above object:

A kind of low-dielectric loss cable comprises:

Oversheath, insulated wire cores;

Described oversheath inside is provided with cellular cavity, and described insulated wire cores is positioned at described cavity and has gap.

Preferably, described insulated wire cores is more than 1, and described insulated wire cores is spaced in described cavity.

Preferably, described cellular cavity comprises the Teflon pipe of a plurality of mutual splicings.

The low-dielectric loss cable that the utility model provides adopts cellular cavity support the built-in electrical insulation core and reduce insulated wire cores and the contact area of cavity, utilizing the reduced dielectric constant dielectric loss that air is lower, is a kind of broad-spectrum low-dielectric loss cable.

The accompanying drawing explanation

Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, does not form to improper restriction of the present utility model, in the accompanying drawings:

Fig. 1 is the utility model example structure schematic diagram.

Embodiment

Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, in this illustrative examples of the present utility model and explanation, be used for explaining the utility model, but not as to restriction of the present utility model.

Embodiment

As shown in Figure 1, a kind of low-dielectric loss cable comprises: oversheath 1, insulated wire cores 2; Oversheath 1 is the structure division that environmental factor corrodes that prevents of protection electric wire; Main Function is the abilities such as moistureproof, the anti-water logging people of the mechanical strength that improves electric wire, anti-chemical burn into, prevention cable fire; insulated wire cores 2 is carriers of electric power, control signal and frequency variation signal transmission; described oversheath 1 inside is provided with cellular cavity 11, and described insulated wire cores 2 is positioned at described cavity 11 and has gap.

As the improvement of above-described embodiment scheme, described insulated wire cores 2 is more than 1, and described insulated wire cores 2 is interior spaced at described cavity 11.

As the improvement of above-described embodiment scheme, described cellular cavity 11 comprises the Teflon pipe of a plurality of mutual splicings, adopts the Teflon pipe of low-k to make cellular cavity 11.

The above technical scheme that the utility model embodiment is provided is described in detail, applied specific case herein principle and the execution mode of the utility model embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; , for one of ordinary skill in the art, according to the utility model embodiment, on embodiment and range of application, all will change, in sum, this description should not be construed as restriction of the present utility model simultaneously.
