1OverviewThe parallel three-phase electric heating tape, in addition to the performance of the parallel single-phase electric heating tape, is particularly suitable for the heat tracing of large-diameter, long-distance pipelines and can balance the grid load. Single-phase is powered by single-phase supply, while three-phase is powered by three-phase delta supply. It can be used in explosive gas mixture areas in Factory Zones 1 and 2.T3Group occasions.

2Structural principlesAs shown in the structural diagram: Three parallel insulated copper flexible wires serve as the power bus, sequentially connected to the power bus at intervals of one heating section length.ab-bc-ca-abAlternating loop connections form continuous parallel resistances between each of the three phases. The busbars are connected to the three phases.380VPower supply, with all parallel resistors heating simultaneously, forming a continuous three-phase power supply heating strip.

5、Product Features: In addition to the same characteristics as single-phase electric heating tape, the three-phase electric heating tape has the following advantages: a) The **** of the three-phase electric heating tape allows for a longer length than that of the single-phase tape. b) In large-scale applications of electric heating tape, it can balance the grid load. c) The three-core wires used in the three-phase tape make the heating tape flatter, reducing the surface heat load and increasing the heat conduction area of the pipe, thereby improving the heat transfer efficiency of the heating tape.
