Changing any key parameters such as supply voltage or cable length will result in the output power differing from the design, which may require recalculation of the entire system and a change in the heating cable type.

Crossing the strands of a constant-wattage heating cable is not permitted. The minimum permissible gap between strands of a constant-wattage heating cable is 20 mm.
