Description：
The principle of three phase constant power electric cable are basically the same, the difference is single phase with the single-phase power supply, three-phase constant power electric heating using three-phase power triangle, three phase besides has the characteristics of single-phase heating cable, especially suitable for long distance, large diameter pipe heat insulation, explosive gas mixture can be used in the factory area, the area of T3 group.
Model:
Product structure and working principle
Three parallel insulation copper stranded wire for the power bus, sheathed on the insulation layer, heating wire winding, at regular intervals and the heating wire (that is, the "long hair eagerly"), respectively, in turn, and the power bus AB - BC - CA - AB...Repeated loop connection, and in every two form continuous parallel connection resistance.When passing a three-phase electric bus, the parallel resistance heating at the same time, thus forming a continuous three-phase power supply heating zone.
