Abstract

The utility model relates to a guide line with a carbon fiber composite core, which comprises a core and an aluminum conductive layer consisting of plural aluminum conductors to coat the core from outside. The core is composed of at least two carbon fibers which are combined together. Since the guide line adopts a core composed of at least two carbon fibers, the diameter of each composite core is smaller than a single carbon fiber composite core contained in another type of guide line. Similarly, the bending stress is also smaller; thereby, the toughness of the guide line with the carbon fiber composite core is increased. Further, the core is capable of distributing curvature from a certain point when bended, thereby, providing a compact structure and a high electric conductivity.

Description

Carbon fiber composite core wire

Technical field

The utility model relates to a kind of stranded type lead, particularly relates to a kind of stranded type carbon fiber composite core wire.

Background technology

Traditional electric power transfer is undertaken by aluminium steel conductor, because this class lead is bigger at electric power transfer process temperature influence, can produce the sag problem, so aluminium steel conductor is replaced by the carbon fiber core lead gradually.A kind of novel carbon fiber composite core wire is arranged at present, it is an aggregate by most carbon fibers, and is composited in the resin binder of being made up of multiple material, and core is wrapped up by electric conductor, because this core has higher modulus of elasticity and lower thermal coefficient of expansion, can improve the ampere-capacity of lead, not only trnamission capacity is big, and high temperature resistant, can not produce obvious sag, result of use is good, and the life-span is long, we can say that this is the development trend of electric power transfer lead.Yet the core of the carbon fiber composite core wire in the industry is made of a carbon fiber complex core usually at present, and its toughness can not well satisfy the demand of carbon fiber composite core wire in application.

Summary of the invention

The purpose of this utility model is to provide the carbon fiber composite core wire of a kind of good toughness, long service life.

The utility model is that the technical scheme that its technical problem of solution is adopted is:

Carbon fiber composite core wire comprises core and by being coated on the aluminium conductor layer that many outer aluminium conductors of core are formed, and described core is to be combined by 2 or above carbon fiber complex core.

Further, described core is by 2 or above stranded the forming of carbon fiber complex core.

The beneficial effects of the utility model: because the core of this lead is to be combined by 2 or above carbon fiber complex core, with respect to core only for the lead of individual carbon fibers composite core, the diameter of every carbon fiber complex core reduces, the bending stress that produces when crooked also reduces, improved the toughness of carbon fiber composite core wire, and the curvature can make bending the time do not concentrate on a place, and structure is tight, the conductance advantages of higher.
