Product Structure and Working Theory
The bus of electrical source is 2 parallel insulating copper wire, twisting heating wire around inner insulating layer, and link heating wire to the bus every other distance (namely “heat nodal length”) , and form consecutive parallel resistance, after electrifying the bus, each parallel resistance is heating, therefore forms a consecutive heating cable.
