The present invention provides a hanger for either casing or tubing strings that electrically insulates the internal suspension system of the hanger from the hanger's external seal. Electrical power is typically transferred through a hanger via the internal suspension system. If electrical umbilicals are used, connecting devices may be located within the internal suspension system for connecting an upper and lower umbilical and transferring power through the hanger. If a rigid tubular conductor is used, the suspension system may be ported to allow the passage of electrical feedthroughs or, in the case of tubing hangers, the tubing itself may be charged with electrical power. By insulating the suspension system from the external seal, potential electrical hazards are eliminated.
