A skin effect heating system for long pipelines includes a heater cable disposed in a ferromagnetic or other conductive heat tube. A semiconductive jacket contacts the inner surface of the heat tube, where the charge density of the return current carried by the heat tube is at its highest. The semiconductive jacket material has a resistivity that is sufficiently low to reduce or eliminate arcing events such as corona discharge by allowing accumulated charge on the heat tube to dissipate. The resistivity is also high enough to prevent the return current from flowing into or through the semiconductive outer layer, so that heat production capacity of the system is maximized.

A power connector includes a housing having a terminal channel holding a terminal. The terminal includes a mating pin at a front of the terminal and a cable connector at a rear of the terminal. The mating pin is positioned in the terminal channel for mating with a charging connector.

The power connector includes a cable heat exchanger thermally coupled to the conductor of the power cable. The cable heat exchanger includes a coolant channel for coolant flow through the cable heat exchanger for actively cooling the conductor of the power cable. A thermally conductive separator electrically isolates the cable heat exchanger from the conductor of the power cable.
