Weblevels, polymer sheds can begin to track and form an electrically conductive path along the surface. The presence of this new conductive path defeats the intended purpose of the insulating material and can lead to a line-to-ground short. These high leakage currents combined with associated dry band arcing can severely damage the polymer surface in WebBecause of lighter weight and smaller in size, this insulator has lower installation cost. It has higher tensile strength compared to porcelain insulator. Its performance is better particularly in polluted areas. Due to lighter weight polymer insulator imposes less load to the supporting structure. Less cleaning is required due to hydrophobic ...
