Parallel heating cable

Type heating cables Parallel, have a power per meter linear constant independent of its length. This allows supplying these in coils, can be cut and finish at work. Characterized in that the heating conductor is wound spirally around the two insulated conductors of the cable, that makes contact with alternatively to time points. The cable forms a system of internal resistors Parallel fed by two conductors.
When cutting the wire between two contact points, will be in the cold regions Heater, one at each end of the heating cable run between the cutting point and the first contact of each end. The cut sections for cable Parallel PCB sound 600 mm for all lengths.
By applying voltage in conductors, heating conductor, receives this same tension between the contact points so, power per linear meter of cable is independent of the length thereof.
