At present, the Huainan area and Anhui Province are mainly arranged vertically. After the relocation and reconstruction of the Luohe large-span line, double-split conductors are vertically arranged and spacers are installed. In the "Major Anti-Accident Measures for "Three-span" Overhead Transmission Lines" issued by the State Grid Corporation of China in 2016, it is required that the "three-span" line be double-split. Split wires should be equipped with spacers. In order to meet the needs of maintenance and renovation work in the future, it is urgent to develop a vertically arranged double-split wire flying car that can pass through spacers.

At present, the flying cars that can be purchased in the market mainly include single-conductor flying cars, horizontal double-split flying cars, and four-split wire flying cars.
