Abstract

885,165. Conduits. OKONITE CO. Nov. 26, 1958, No. 38086/58. Drawings to Specification. Class 36. An alternating current power cable system comprises a plurality of single- or multicored insulated cables disposed within a ferromagnetic conduit, the interior surface of which is interrupted by closely spaced narrow circumferential slits cut into the conduit wall, these slits being either separate circumferential slits or continuous helical slits, and the conduit. being annealed. The effect of the electrical discontinuities provided by the slits may be enhanced by filling the slits with insulating lacquer, by heat treatment to provide an oxide film or by filling the conduit with oil. U.S.A. Specification 2,787,651 is referred to.
