Abstract

Methods are provided of producing a heater cable. An electrical conductor is coated with a preceramic resin. At least a portion of the coated electrical conductor is deployed into a operational location. The preceramic resin is pyrolyzed while the portion of the coated electrical conductor is in the operational location to convert the preceramic resin into a ceramic insulator disposed to electrically insulate the electrical conductor from the sheath.
