The Medium temperature type self regulating heating cable developed by Anhui Tiankang (Group) Co., Ltd. is widely used in the pipelines and storage of petroleum, chemical, steel, electric power and other industrial enterprises for heat tracing, heat preservation, anti-coagulation, and anti-freezing. The cable is suitable for common areas, dangerous areas and corrosive areas.
Medium temperature type self regulating heating cable structure
(1) Copper core wire: 19×0.32mm
(2) Conductive plastic layer: ordinary PTC, flame-retardant PTC;
(3) Insulation layer: other applicable materials such as irradiated flame-retardant polyolefin, perfluorinated material, etc.;
(4) Shielding layer: tinned soft round copper wire or other metal wire, covering density not less than 80%;
(5) Sheath layer: flame-retardant polyolefin, perfluorinated materials and other applicable materials.
Medium temperature type self regulating heating cable Technical index
(1) Nominal power: 35W/m, 40W/m, 45W/m, 50W/m, 55W/m
(2) Voltage level: 110V, 120V, 220V, 380V, 660V
(3) Standard color: brown (customizable);
(4) Temperature range: the highest working temperature is 90℃; the highest surface temperature is 110℃; the highest temperature is 205℃;
(5) Construction temperature: minimum -40℃;
(6) Thermal stability: After cycling back and forth 300 times from 10°C to 105°C, the heating value of the cable is maintained above 90%;
(7) Deflection radius: 30.4mm at -20℃, 40.6mm at -30℃;
(8) Insulation resistance: the insulation resistance between the conductor and the metal sheath/shielding layer should not be less than 500MΩ;
Compared with low temperature heating cables, the Medium temperature type self regulating heating cable has higher heating temperature and good antifreeze effect. The ambient temperature is -10℃, the surface temperature of the heating cable is 105℃±5℃, and the highest temperature is 135℃. The heating cable is conductive by polymer Carbon particles and two parallel bus bars are formed with an insulating layer. The resistivity of the PTC heating element has a high positive temperature coefficient and is connected in parallel.
