Abstract
Abstract A multi-purpose junction box and a flexible, easily removable high voltage underground type cable are used to connect a high voltage underground transmission line terminating in a pothead, to a power transformer. The pothead terminating high voltage underground transmission line terminates in a multi-purpose junction box with the central conductor of said transmission line being connected to electrical connecting means internal of the junction box. The flexible cable, in turn, connects the power transformer to the electrical connecting means internal of the multipurpose junction box.
