| Abstract: | The use of backward V type insulators in 500kV transmission line is an effective way to prevent insulators ice flashover,but span,height difference,and uneven ice load of transmission line in mountain areas would cause the longitudinal unbalanced tension of the tower exceeding the design value.The characteristics of the backward V type insulators were analyzed and the check-up calculation must be done before the application of backward V type insulators in upland transmission line.The reliability of the calculation was verified by real loading experiment.Finally,the check-up calculation was applied in the modification of backward V type insulators in 500kV Wulou transmission line. |
