Connecting a "pothead" to overhead primary phase
Just to open this discussion to the general forum, for educational purposes only.
When a URD system is fed from an overhead primary source, the connection is made at the cable pole. The device that actually makes the connection is a “pothead” (Figure 2-1). One end of the “pothead” is connected to the overhead primary and the other end is connected to the URD primary cable. The “pothead” provides the connection between the URD system and the Overhead System and a termination point for the URD cable insulation.
Question - How is the physical connection to the primary overhead phase cable made. Is the connection a clamp connection to the overhead cable or is it a terminal connection?
