Abstract
A method for making mineral insulated cables in which a mineral powder is purified to remove magnetic particles. The purified mineral powder and at least one wire are fed into a seam-welded metal sheath as it is being formed to produce the mineral insulated cable. The mineral insulated cable may then be drawn and annealed to reduce the diameter of the cable to the desired size.
