Pothead
Encyclopedia
A pothead is a type of insulated electrical terminal used for transitioning from overhead to underground high voltage cable
or for connecting overhead wiring to equipment like transformer
s. Its name comes from the process of potting
or encapsulation of the conductors inside the terminal's insulating bushing

High voltage cable
A high voltage cable - also called HV cable - is used for electric power transmission at high voltage. High voltage cables of differing types have a variety of applications in instruments, ignition systems, AC and DC power transmission...

Transformer
A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors—the transformer's coils. A varying current in the first or primary winding creates a varying magnetic flux in the transformer's core and thus a varying magnetic field...

Potting (electronics)
In electronics, potting is a process of filling a complete electronic assembly with a solid or gelatinous compound for resistance to shock and vibration, and for exclusion of moisture and corrosive agents...
