RDC
RDC series connection constant wattage heating cable use the core conductor as the heating element, when the core conductor connect to power supply, the core conductor 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 pipe-line and large diameter pipeline's heat tracing and heat preservation. Power supplied by one power point.
