Construction
Asphalt from the asphalt machine in general has a temperature of 170-220 °C. SMC-FE cables and SMM-FE mats are suitable for withstanding this temperature for up to 10 minutes. The cable is developed according to IEC 60800 Class C, which means that the cable has deformation strength of 2000N.
The ThermoTAR range consists of a resistance element provided with primary high temperature polymer insulation, earth screen and secondary insulation of high temperature material.
Heating cables could be single conductor with approx. 6.5mm outer diameter terminating on cold leads at two ends of the cable or it could be twin conductor with approx. 7.5mm outer diameter and terminating on cold leads at one end of the cable. SMC-FE and SMM-FE comes with a standard 5.0 m length cold lead.
