Series constant power RDC series
RDC series constant power heating cables use metal conductors as heating elements, and when the power is turned on, the metal conductors emit heat because the series constant power tracing unit length current and resistance are equal. So the calorific value of each unit is the same. The tail end does not have less power than the head end as the length increases, so this product is suitable for heat tracing and insulation of long pipes and large diameter pipes.
