Description

Strand type carbon fiber core electrical lead

Technical field

The utility model is related to a kind of power transmission cable, more particularly to a kind of strand type carbon fiber core electrical lead.

Background technology

Power Transmission plays more and more important role in the development of national economy, and the wire of power Transmission is always It is the main carriers in electric power energy conveying.Currently, the species of electrical lead increases increasingly, although still using steel-cored aluminium strand as It is main, but other kinds of novel electric power wire is also occurred in that simultaneously, especially using the electrical lead of core rod type carbon fiber core as main flow generation Table, with great popularizing application prospect.However, in the carbon fiber core electrical lead of core rod type carbon fiber core but exist be processed into Type is more difficult, environmentally friendly cost is larger, and particularly carbon fiber plug has minimum diameter excessively thick（≧5mm）, plug excessively it is crisp it is really up to the mark, bending The shortcoming that radius is excessive, easily snaps off and should not be extruded by radial side.

The content of the invention

In view of the shortcomings of the prior art, the utility model provides a kind of strand type carbon fiber core electrical lead.

The technical solution adopted in the utility model is：A kind of strand type carbon fiber core electrical lead, including wire and load-bearing Core, it is characterized in that：The load-bearing core includes carbon fiber layer and external insulation layer, and the carbon fiber layer is three or seven T800H type carbon fiber bundles are stranded to be formed, external insulation layer described in carbon fiber layer outer wrapping.

Described strand type carbon fiber core electrical lead, it is characterized in that：The carbon fiber layer is divided to two for seven carbon fiber bundles Layer is stranded to be formed, wherein, internal layer is a carbon fiber bundle, and outer layer is six roots of sensation carbon fiber bundle, every fibre bundle outer wrapping interior insulation Layer.

Described strand type carbon fiber core electrical lead, it is characterized in that：The carbon fiber layer lay ratio is less than or equal to 20.

The utility model uses T800H type carbon fibers, is required according to varying strength, by its it is stranded be three cores or seven cores, and Lay ratio is less than 20, makes its stranded rear uniform force.Inner insulating layer is wrapped up on every carbon fiber, wraps up outer after stranded shaping again Insulating barrier, that is, maintain carbon fiber lightweight, softness, high-strength, corrosion resistant, conductive characteristic, and with high tensile strength.
