Abstract
An electrode unit for electrically heating underground hydrocarbon deposits having a main conduit pipe assembly, a cylindrical water pipe and an electrical conductor arranged coaxially with the electrical conductor disposed between the water pipe and the main conduit pipe assembly. The spaces between the main conduit pipe assembly and the cylindrical water pipe are filled with a solid insulating material, wherein it is not necessary to recirculate cooling oil through the assembly. Connectors are disposed for joining ends of adjacent main conduit pipe assemblies, ends of adjacent water pipes and electrical conductors. Preferably, the electrical conductor is made of a material such as a metal mesh which can stretch longitudinally.
