Abstract

142,292. British Thomson - Houston Co., (General Electric Co.). April 29, 1919. Cables and compound conductors.-A number of auxiliary conductors 23 - - 26 surround the main conductor 20 of a cable and are lightly insulated from it, the whole being embedded in insulating-material 21 and surrounded by a lead sheath 22. The auxiliary conductors are connected together in two groups and control cutout devices at the ends of a section of cable.
