The Research Of Carbon Fiber Core Wire Aging Test In Method Of Integrated Factors

Compared with the Aluminum Conductor Steel Reinforced(ACSR)in the same standard,Aluminum Conductor Composite Carbon(ACCC)has the following advantages:light weight,high tensile strength,small linear expansion coefficient,little sag,big current-carrying capacity,high temperature resistance,corrosion resistance etc.Therefore,with the growing demand for electricity,ACCC usage is growing gradually.Although ACCC has the inherent corrosion resistance characteristic of the composites,when exposed to high temperature,high humidity,ultraviolet light,ozone,breeze vibration,acid rain corrosion,freezing rain or snow environment,aging will happen.So that,ACCC aging research becomes more and more urgent.The research method of single factor aging test research for ACCC is mainly ripe.On this basis,this paper proposed a integrated factors test method,and manufactured a corresponding aging experimental device.The device simulated the realistic working condition by the artificial light,high temperature and high humidity,salt spray,rain and other environment factors.At the same time,the power frequency voltage,tension,corona cage and other experimental conditions were added to achieve the coincidence with the realistic condition.Based on the experimental device,we successfully carried out integrated factors' 1000 hours of continuous aging test according to the procedures requirement.Certain aging phenomenon of the sample's is accelerated by the experiment.A novel set of before and after aging comparative analysis program is designed:electron microscopy before and after aging wire fracture and surface analysis,DSC/IR study of the glass transition temperature,metal galvanic corrosion research.Through these microscopic study,we get the further analysis result of after aging performance and put forward a type of fatigue life prediction method.
