JL1X1/LHA1-1040/550 development of aluminum alloy core forming aluminum twisted line pair splicing sleeve

摘要

UHVDC project will be prepared by JL1X/LHA1-1040/550 aluminum alloy core forming aluminum twisted line to reduce the load on the tower, improves the safety performance of the circuit, and has the function of upgrading line capacity. For such a wire, the domestic currently has no relevant research experience of line pair splicing sleeve, in order to meet the needs of practical engineering, this paper completed the pair splicing sleeve material and a compression ratio development according to the structural characteristics of this guide line; through a splicing sleeve manufacturing and testing, the development of aluminum JL1X/LHA1-1040/550 aluminum alloy core aluminum twisted wire pair splicing sleeve grip strength meets 95%RTS.
