2. Trace heating - Wikipedia

   en.wikipedia.org/wiki/Trace_heating

   Electric heat tracing, heat tape or surface heating, is a system used to maintain or raise the temperature of pipes and vessels using heat tracing cables. Trace heating takes the form of an electrical heating element run in physical contact along the length of a pipe.

3. Mineral-insulated copper-clad cable - Wikipedia

   en.wikipedia.org/wiki/Mineral-insulated_copper...

   A similar-appearing product is mineral-insulated trace heating cable, in which the conductors are made of a high-resistance alloy. A heating cable is used to protect pipes from freezing or to maintain the temperature of process piping and vessels. An MI resistance heating cable may not be repairable if damaged.

4. Direct-buried cable - Wikipedia

   en.wikipedia.org/wiki/Direct-buried_cable

   Cross-section of direct buried cable. Direct-buried cable (DBC) is a kind of communications or transmissions electrical cable which is especially designed to be buried under the ground without any other cover, sheath, or duct to protect it. [1] Most direct-buried cable is built to specific tolerances to heat, moisture, conductivity, and soil ...

5. Electrical resistance heating - Wikipedia

   en.wikipedia.org/wiki/Electrical_resistance_heating

   Electrical resistance heating (ERH) is an intensive in situ environmental remediation method that uses the flow of alternating current electricity to heat soil and groundwater and evaporate contaminants. [1] Electric current is passed through a targeted soil volume between subsurface electrode elements.

6. Soil thermal properties - Wikipedia

   en.wikipedia.org/wiki/Soil_thermal_properties

   Example of a complete system for measurement of soil thermal conductivity, specially designed for measurements at around 1.5 meters below the soil surface, which is the typical depth of burial for high voltage cables. After further research the dual-probe heat-pulse technique was developed.

8. Heat flux sensor - Wikipedia

   en.wikipedia.org/wiki/Heat_flux_sensor

   Diameter 80 mm Heat flux sensor mounted on a window. Heat flux sensors can be used like this to determine the R-value or U-value of building envelope materials while they are still installed in buildings. A heat flux sensor is a transducer that generates an electrical signal proportional to the total heat rate applied to the surface of the sensor.
