The connection point between an underground cable and an overhead conductor is typically made through a pothead. Potheads are specialized connectors that provide a secure and effective transition from the cable to the overhead line. They are designed to handle the stresses of both the underground and overhead components, ensuring a reliable electrical connection while also protecting against environmental factors such as moisture and electrical stress.

In contrast, transformers are used to change voltage levels and are not specifically designed for connecting underground cables to overhead lines. Insulators, while crucial for maintaining safety and voltage integrity by preventing unwanted electrical discharge, do not serve as connection points. Arresters are protective devices used in electrical systems to divert surge currents but do not function as a connecting mechanism for cables. Thus, the pothead is the proper choice for this type of connection due to its intended design and functionality.
