Substation Equipment: Potheads

Potheads
A type of insulator with a bell or pot-like shape used to connect underground electrical cables to overhead lines. It serves to separate the bunched-up conductors from one another in the cable to the much wider separation in the overhead line. It also seals the cable end from the weather. Potheads are mounted on a distribution pole and the assembly is called a riser pole.
