Two-core heating cable with constant power is supplied in ready-made sections.

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.
