Abstract

A kind of carbon fiber core aerial insulated cable, including wire and load-bearing core, the wire outer wrapping cable insulation, the load-bearing core includes 19 T800H type carbon fiber bundles, and the carbon fiber bundle is divided into single layer, internal layer and outer layer, and the internal layer is formed by 6 carbon fiber bundles are stranded, the outer layer is twisted into by 12 carbon fiber bundles, adjacent layer direction of lay is on the contrary, external insulation layer is wrapped up in every carbon fiber bundle parcel inner insulating layer, the outer layer outsourcing.

Description

Carbon fiber core aerial insulated cable

Technical field

The utility model is related to a kind of power transmission cable, more particularly to a kind of carbon fiber core aerial insulated cable.

Background technology

Nowadays aerial insulated cable is increasingly widely used among the transformation of ring of city electrical network and rural power grids, but no matter city Or rural area, building height and building scope all expand in continuous lifting, and for the sustainable living environment of the mankind, live Green coverage and require also increasing higher, so to the sag and span and weight of aerial insulated cable naturally Propose higher requirement and standard.

The content of the invention

In view of the shortcomings of the prior art, the utility model provides a kind of carbon fiber core aerial insulated cable.

The technical solution adopted in the utility model is：A kind of carbon fiber core aerial insulated cable, including wire and load-bearing line Core, the wire outer wrapping cable insulation, the load-bearing core includes 19 T800H type carbon fiber bundles, the carbon fiber bundle It is divided into single layer, internal layer and outer layer, the internal layer is formed by 6 carbon fiber bundles are stranded, and the outer layer is by 12 carbon fiber bundle strands Synthesis, adjacent layer direction of lay are on the contrary, external insulation layer is wrapped up in every carbon fiber bundle parcel inner insulating layer, the outer layer outsourcing.

A kind of described carbon fiber core aerial insulated cable, it is characterized in that：Each stranded layer lay ratio subtracts successively from inside to outside Few, the internal layer lay ratio is less than or equal to 20, and the outer layer lay ratio is less than or equal to 18.

Tension load-bearing stress unit of the utility model using strand type carbon fiber core as aerial insulated cable, mainly just like Under several effects：

1st, the performance indications such as the current-carrying capacity of original aerial insulated cable are maintained constant；

2nd, the line density that is sufficiently used carbon fiber is smaller, tensile strength is high, elongation percentage very little and other performances Advantage；

3rd, stranded processing molding method has been used, the pull-off force of carbon fiber has not only been added but also has maintained carbon fiber core Carbon fiber core rounding after uniform stressed, and shaping so that its will not cross as hard as it is crisp, will not be squeezed fractures, soft pliable is bent, A layer insulating is extruded after stranded shaping again；

4th, the carbon fiber core structure of strand type, Stability Analysis of Structures so that the pliability of aerial insulated cable is greatly enhanced, weight Mitigate significantly, can improve erection span, reduce set up sag, extension set up distance so that construction convenience greatly improve, Expense is reduced and improved significantly uses degree of safety.
