The heating source for the Mightyband heater is a resistance wire in straight form or wound into a miniature helical coil. The swaging and drawing process involved in manufacturing the heater cable for Mightyband heaters compacts the ceramic insulators that house the heating element and thermocouple wire into a solid mass, producing a rugged and durable heater cable, providing excellent thermal conductivity and
dielectric strength and quick thermocouple response.
