HEATING CABLES K15A SELF-ADJUSTING HEATING CABLES FOR PIPELINES, GUTTERS, DOWNSPOUTS AND ROOFS ■ Suitable for protection against the freezing of water pipes and to prevent the formation of ice on roofs and gutters ■ Power delivered ~15 W/m at 5°C ■ Optimisation of energy consumption thanks to the self- adjusting feature of the cable CODE Cable Minimum Maximum Maximum Maximum length length installation room room of the heating room temperature temperature circuit temperature powered not powered from the supply point K15A25 25 m -35 °C 65 °C 80 °C 110 m K15A50 50 m -35 °C 65 °C 80 °C 110 m K15A75 75 m -35 °C 65 °C 80 °C 110 m K15A100 100 m -35 °C 65 °C 80 °C 110 m K15A500 500 m -35 °C 65 °C 80 °C 110 m K15A1000 1000 m -35 °C 65 °C 80 °C 110 m HOMOLOGATION AND STANDARDS OPERATION ■ CSTB ■ The heating cables automatically vary the heat emission without control thermostats being used; ■ They consist of conductors insulated by polymers, which vary their resistance according to the temperature which they are subjected to. 1 K15A - SELF-ADJUSTING ANTIFREEZE HEATING CABLES FOR ROOFS AND GUTTERS INSTALLATION ■ The cable can be cut to the desired length; ■ In case of installation for roof protection, the cable must be laid with a serpentine path; ■ In case of installation for the protection of downpipes and gutters, the cable must be secured longitudinally; ■ In case of installation for the protection of small pipes, the cable can be secured linearly along the pipe with the relevant fixing tape; ■ For medium-large pipes, on the other hand, the heating cable may need to be wound so as to ensure adequate prevention against frost forming inside the pipe; ■ Refer to the table below to check whether the cables must be wound in a spiral with an increase in the required length; ■ The power of a metre of cable varies with temperature; the total power therefore, depends on the length of the heating cable. The heating core is active along the entire length of the cable, therefore, a cold end must be created so as to have a section with cold tail.
