Abstract
An electrical conductor of the type having a central cavity which extends along the longitudinal axis of the conductor to conduct refrigerating fluid which cools the conductor heated by high current density current flow whereby, to increase thermal efficiency and decrease deposits on the walls of the cavity which reduce the lifetime of the conductor, the cavity walls have non-smooth undulations, forming for example isosceles triangles.
