Cable substitute for mineral-insulated cables in nuclear facilities

An electrical cable for use in nuclear facilities and resistant to irradiation in excess of 200 Megarads, the electrical cable comprising:

• at least one conductor;
• insulation wrapped around the at least one conductor, the insulation comprising mica tape applied in overlapping layers around the at least one conductor, wherein the mica tape includes an elastomeric layer that bonds the overlapping layers and converts to an inorganic material after undergoing an oxidative pyrolysis process yielding a completely inorganic insulation;
• a jacket comprising a woven glass braid, wherein the jacket is applied over an exterior of the insulation;
• and
• an armor shell applied around the at least one conductor, the insulation, and the jacket, wherein the armor shell forms an exterior of the cable.

An electrical cable suitable to limit transmutation from neutron irradiation exposure, the electrical cable comprising:

• at least one conductor;
• insulation wrapped around the at least one conductor, the insulation comprising mica tape applied in overlapping layers around the at least one conductor, wherein the mica tape includes an elastomeric layer that bonds the overlapping layers and converts to an inorganic material after undergoing an oxidative pyrolysis process yielding a completely inorganic insulation;
• a jacket applied over an exterior of the insulation;
• and
• an armor shell applied around the at least one conductor, the insulation, and the jacket, wherein the armor shell forms an exterior of the cable.
