Abstract

Blocks (60, 65) of magnesium oxide or other mineral insulant are formed with grooves (62). Copper conductors (63) are laid in the grooves (62) and the blocks (60, 65) are held in place on the conductors (63) by a layer of insulating tape (66). A copper tube (68) is formed around the layer (66), and the whole is then subjected to alternating steps of drawing or rolling and annealing to form a mineral insulated cable.
