Experimental Research on Performance of Composite Materials Pole of 110kV Transmission Line

The electrical performances of 2 types of grounding of 110kV composite materials pole,and the mechanical performance of 3 forms of structure of 110kV composite materials pole,were experimentally investigated,and the operation performance was analyzed.The test results reveal that,compared with that of the steel pole,the insulating level of composite materials pole is remarkably improved after adopting proper grounding method,and the strength of composite materials pole satisfies the demands of load of transmission line,but the deflection of composite materials pole is more than that of steel pole.Consequently,insulation of the composite materials poles can greatly improve the insulation level and reduce the fault of transmission lines,such as windage yaw,pollution flashover,icing flashover,and lightning trip.
