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.
PVC-sheathed MICC cable. Conductor cross section area is 1.5 mm 2; overall diameter is 7.2 mm. Mineral-insulated cables at a panel board. Mineral-insulated copper-clad cable is a variety of electrical cable made from copper conductors inside a copper sheath, insulated by inorganic magnesium oxide powder.
Linear heat detection (LHD) cable is essentially a two-core cable terminated by an end-of-line resistor (resistance varies with application). The two cores are separated by a polymer plastic, that is designed to melt at a specific temperature (commonly 68 °C for building applications [1]), and without which causes the two cores to short.
For uninsulated cables (typically used in outdoor overhead installations), the tensile strength of the cable (as affected by temperature) is normally the limiting material property. The Neher–McGrath method is the electrical industry standard for calculating cable ampacity, most often employed via lookup in tables of precomputed results for ...
In addition to being halogen-free, when the compound reaches a specific temperature, it absorbs heat energy, releases steam and does not release corrosive gases. This can make its application more extensive; for example, in new nuclear power plants, the use of LSZH cables and conduits will increase. Fourth: flame retardant. Due to the chemical ...

This type of cable is the least expensive for a given size and is appropriate for dry indoor applications. The designation NM XX - Y indicates, respectively, the type of sheathing (in this case, non-metallic), the size of the main conductors, and the total number of circuit conductors (exclusive of the grounding conductor).
