Others How it works As the temperature surrounding the cable decreases, the conductive core contracts on a microscopical level, decreasing the electrical resistance and creating numerous electrical paths between the conductors. Current flows along these paths to warm the core. As the temperature rises, the core expands on a microscopical level, increasing electrical resistance and decreasing the number of electrical paths.
As a result, the heating cable can be overlapped several times without risk of degradation, since the power is greatly reduced at high temperatures. Benefits 1. More uniform temperatures Because the heater senses and responds to actual conditions along the pipe, the system accommodates variations due to static fluid and differing elevations.
Applications Any process in pipes, tanks or vessels for freeze protection, temperature maintenance, viscosity control, or anti-condensation.
Typical industries include: Oil and gas exploration, production, refining, distribution Chemical and petrochemical; Power bio-diesel, solar, hydro This special blend of materials extruded between the conductors creates electrical resistive paths.
The number of electrical paths changes in response to temperature fluctuations. These heating cables are available in two different outer jacket materials. The polyolefin outer jackets -CR are suitable for use in areas where the cables will only be exposed to mild inorganic solutions whereas the fluoropolymer outer jackets -CT offer a high general chemical resistance.
The products are approved for use in hazardous areas Zone 1, Zone 2 Gas , Zone 21 and Zone 22 Dust and have an absolute temperature classification of T6 in accordance with European Standard EN These heating cables all have fluoropolymer outer jackets offering a high chemical resistance. The products are approved for use in hazardous areas Zone 1, Zone 2 Gas , Zone 21 and Zone 22 Dust and have an absolute temperature classification of T4 in accordance with European Standard EN XTV The XTV range of self-regulating heating cables is used for frost protection of pipes and vessels that require steam cleaning.
KTV The KTV range of self-regulating heating cables is mainly used for frost protection of pipes and vessels that require steam cleaning. The products are approved for use in hazardous areas Zone 1, Zone 2 Gas , Zone 21 and Zone 22 Dust and have an absolute temperature classification of T2 in accordance with European Standard EN VPL The VPL range of power-limiting heating cables is mainly used for temperature maintenance of processes and offers the advantage of a high power output at high temperatures which can reduce the number of heating cables required.
They can also be used for frost protection of pipes and vessels that require steam cleaning. The V version offers the further advantage of long circuit lengths potentially reducing the number of supply points required.
Unlike the self-regulating heating cables the T-classification for these products has to be calculated and will depend on the design conditions, this may also result in the need to use a safety temperature limiter.
