Ultra High Voltage Expanded Diameter Overhead Conductor

Expanded diameter wire   Expanded diameter wire is a special overhead wire developed specifically for ultra-high voltage and extra high voltage transmission projects. The mainstream models include LGJK drawn strand expanded diameter wire and LGKK inner tube expanded diameter wire, which are suitable for high voltage transmission scenarios above 220kV, especially for high-altitude, long-distance, and large capacity transmission projects. It is the core wire for reducing losses, increasing efficiency, and saving infrastructure costs in high-voltage power grids. The product is designed with a special hollow and gap expansion structure, which optimizes the aluminum cross-section structure, reduces the weight of the wire, effectively reduces the load on the iron tower and the overall cost of the line, and solves the industry pain points of high corona loss, high line reactance, and high infrastructure cost of traditional wires under ultra-high voltage conditions, while meeting the outer dia…
