Winning WPI-53-2 Spool Insulators are produced of a proprietary high density polyethylene, which features good track resistance, greater leakage distance, higher flashover and impulse values, as well as other superior mechanical performances such as lighter weight, anti-crack etc. 

They are mounted to the pole using various clevis confirguations and are compatible with all manufacturers' designs. They are shaped like spinning spools, which allow them to hold wires in place, and keep them from slipping off. These HDPE Spool Insulators are designed, manufactured and tested to the spool insulator requirements of ANSI Standard C29.3.
