High-voltage AC overhead transmission lines: As the core insulating component, they are applied in 10kV and above high-voltage overhead transmission lines to achieve insulation and isolation between conductors and towers as well as the ground. They can withstand the mechanical tension of the lines and high-voltage impacts, ensuring the safety and stability of power transmission in remote areas and across regions.
Substations and power distribution systems: The insulation and fixation of external live conductors of busbars and electrical equipment in various substations, achieving isolation of different potential conductors during the substation process, can withstand the complex electric field environment within the substation and prevent problems such as leakage and short circuits.
