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.
An electrode unit for electrically heating underground hydrocarbon deposits comprising: a main conduit pipe; a cylindrical water pipe disposed within and coaxially to said main conduit pipe; a cylindrical electrical conductor disposed between said water pipe and said main conduit pipe; and a solid h
An electrode unit for electrically heating underground hydrocarbon deposits comprising: a main conduit pipe; a cylindrical water pipe disposed within and coaxially to said main conduit pipe; a cylindrical electrical conductor disposed between said water pipe and said main conduit pipe; and a solid heat insulating material disposed in spaces between said water pipe and said main conduit pipe. The electrode unit of claim 1 further comprising first and second connectors for connecting electrical conductors between adjacent electrode units, said first and second connectors being disposed at the opposite ends of said electrode unit, said first connector comprising a ring-shaped connecting terminal disposed coaxially between said water pipe and said main conduit pipe, and said second connector comprising a plurality of contactors arranged cylindrically and movable radially adapted for making contact with a ring-shaped connecting terminal of an adjacent electrode unit while providing a predetermined contact pressure, said contact is being coupled to said electrical conductor through a second ring-shaped connecting terminal arranged coaxially with said water pipe at said second end.
