Abstract

The large cross-section conductors with 1000mm2 sectional area are widely applied in South Hami - Zhengzhou ± 800kV UHVDC power transmission project. The Al wires withstand relatively high tension for the large ratio of Al to steel, so the grip strength of crimping tube designed according to traditional experiences cannot meet the requirements of standard. Optimized design of crimping tube is necessary to minimize the strength loss of Al wires caused by crimping and improve grip strength. Orthogonal test schemes basing on combinations of different inner diameters and taper lengths of tube are designed after analyzing the factors which influence the grip strength. The influencing effects on grip strength of inner diameters and taper lengths are discovered by normal statistical analysis on test results of different tubes and the same conductor. The guaranteed value of grip strength residual ratio for optimal tube is gained. Optimal sizes of hydraulic tube are recommended to manufacturer, and sampling test results indicate that optimized fittings achieve the expected results.
