Abstract: The application status and problems of the “T-joint” wiring method was introduced in the high-voltage distribution network in Dongguan.By constructing a comprehensive quantitative evaluation model for the wiring mode of the high-voltage distribution network, the four typical “T-joint” wiring modes of the high-voltage distribution network were comprehensively evaluated.The optimization measures for the wiring method of the high-voltage distribution network wiring in Dongguan were proposed.
