Abstract: A mineral insulated heating cable for a heat tracing system. The heating cable includes a sheath having at least a first, and optionally a second layer, wherein the thermal conductivity of the second layer is greater than a thermal conductivity of the first layer. In addition, the first and second layers are in intimate thermal contact. The heating cable also includes at least one heating conductor for generating heat and a dielectric layer located within the sheath for electrically insulating the heating conductor, wherein the sheath, heating conductor and dielectric layer form a heating section. In addition, the heating cable includes a conduit for receiving the heating section. Further, the heating cable includes a cold lead section and a hot-cold joint for connecting the heating and cold lead sections. In addition, a high emissivity coating may be formed on the first layer.

Abstract: A skin effect heat tracing system including a heat tube and a heater cable with a core conductor and an electrical insulation layer surrounding the core conductor. The heater cable is sized to lie within the heat tube so that a gas-filled space is defined between an outer surface of the electrical insulation layer and an inner surface of the heat tube. During operation of the skin effect heat tracing system, the gas-filled space may be pressurized, by a gas source, above an external pressure outside the heat tube.

Abstract: A heater cable for use in a heat tube. The heater cable includes a core conductor, an electrical insulation layer surrounding the core conductor, and an outer semiconductive layer surrounding the electrical insulation layer. The outer semiconductive layer is exposed so that, when installed in the heat tube, the outer semiconductive layer is in physical and electrical contact with an inner diameter of the heat tube. The outer semiconductive layer, or jacket, has ribs or similar spacing structures that contact the inner surface of the heat tube and space the components of the heater cable away from the inner surface of the heat tube and toward the center of the heat tube to reduce or eliminate the incidence of partial discharge.

Abstract: A skin effect heating system for long pipelines includes a heater cable disposed in a ferromagnetic or other conductive heat tube. A semiconductive jacket contacts the inner surface of the heat tube, where the charge density of the return current carried by the heat tube is at its highest. The semiconductive jacket material has a resistivity that is sufficiently low to reduce or eliminate arcing events such as corona discharge by allowing accumulated charge on the heat tube to dissipate. The resistivity is also high enough to prevent the return current from flowing into or through the semiconductive outer layer, so that heat production capacity of the system is maximized.

Abstract: A skin effect heating system for long pipelines includes a heater cable disposed in a ferromagnetic or other conductive heat tube, the heater cable and heat tube cooperating to produce heat that is applied to the carrier pipe. The heater cable includes a conductor surrounded by an insulating layer that includes a generally tubular core insulation and a plurality of structural spacers extending from the core insulation. The spacers dispose the conductor closer to the center of the heat tube, and space the core insulation away from the heat tube in order to minimize or eliminate partial discharge at voltages in excess of 5 kV. The spacers may be axial or lateral “ribs” that contact the inner surface of the heat tube and create an air gap between the heat tube and the core insulation, the air gap significantly reducing charge buildup on the outer surface of the core insulation.
