RDC series constant wattage heating cables use the core conductors as the heating element, when the core conductors connected to power supply, the core conductors will send out joule heat, same as they are of the entire cable length, the heating value of each unit is the same. This will not result in a situation that the power in the terminal end is lower than it is in the beginning end as the heating cable length increases. So this type is suitable for long pipeline and large diameter pipeline’s heat tracing and heat preservation. Power supplied by one power point.
