  How RTV Coating Affects Creepage Distance and Leakage Current？

  RTV (Room Temperature Vulcanized) silicone coating is widely applied to high-voltage insulators to enhance anti-pollution performance and improve long-term electrical reliability,While RTV coating does not physically increase the geometric creepage distance,it significantly alters surface electrical behavior by maintaining hydrophobicity,reducing leakage current,and effectively improving the electrical creepage performance of insulators under polluted and wet conditions,

  Residual Mechanical Strength of Glass Insulators

  Residual Mechanical Strength is a key indicator used to evaluate how much load a glass insulator can still withstand after it has been damaged,It is directly related to the safe and reliable operation of transmission lines when local damage occurs to an insulator,Simply put,the higher the residual mechanical strength,the less likely a self-exploded or mechanically damaged insulator is to cause a full string failure or conductor drop,

  Glass Insulator V-String for High-Voltage Transmission Lines

  A glass insulator V-string,sometimes called a V-suspension string,V-type insulator assembly,or V-shaped tension string,is formed by connecting two toughened glass insulator chains between the tower cross-arm and the transmission line conductor,The angle between the two strings typically ranges from 30° to 60°,depending on mechanical design requirements,Glass insulator V-strings are widely used in high-voltage and extra-high-voltage transmission lines to increase mechanical stability,reduce conductor swing,and enhance line reliability during heavy wind,ice,and storm conditions,
