DEFINITION

Classification: 338/243

(under subclass 226) Subject matter wherein the resistance element is substantially entirely enclosed in an insulating layer, which is either a solid mass of insulating material or a noninsulating material coated or otherwise covered with insulation to present an insulated surface, and a metallic layer substantially entirely surrounding or enclosing the insulating layer to provide a sheath.
