Parallel Three-phase Constant wattage heating cable use the core conductor as the heating element .
Resistance and current per unit length is equal to the whole the heating value of each unit is equally without
termination power lower than the beginning with the increasing length use.
Further more,it adopts three-phase electric power supply.Therefore,it is suitable for long pipeline and large diameter
tracing and maintenance.
Set up an three phase electric circuit to the electric power bus and then the shunt resistance heating,thus forming a continuous heating cable.
Compared to single-phase heating cable,three-phase heating cable has the characteristics FDP2 has, it also has below advantages:
1. The max allowed length of three-phase heating cable is greater than that of single-phase heating cable.
2. It helps to relieve the electricity load in large-scale heating cable applicable net.
3. Due to three bus wires , heating cable is more flat and increase transfer heat areas and energy efficiency. Strengthen range is that ordinary rang add a oversheath and high strength mechanical and corrosive-proof feature.
Three-phase constant watt heating cable provides frozen-prevention and temperature-maintenance of pipelines and valves which is same for single-phase constant watt heating cable. However, when applied to long-distance and big-diameter pipes, using of three-phase heating cable is more economic and reasonable and showing more advantage.
