Heating cable installation for e.g. floor heating, comprises series resistive cable which can be cut to length and power regulator with variable setting depending on cable length

摘要

The installation comprises a series resistive cable (10) which can be cut to the desired length and which has a given resistivity and perceptible effect per unit length, as well as a power regulator (30) for connecting between the cable and power source (70). The regulator has different power settings (62) determined by the cable length, resistivity and perceptible effect.
