They are completely waterproof, extremely flexible and functional thanks to the specific characteristics of their constituent materials and their particular construction technology. The latter consists of a resistive wire made of Nickel/Chromium or Copper/Nickel or similar alloys wound on a support made with a fibre glass filament. The winding thus obtained is externally protected by a special silicone compound that guarantees a high dielectric seal and allows the cable to operate within a wide temperature range: from -60°C to +200°C. The same compound is subsequently used for the manufacture of the outer sheath, permanently enfolding the resistive heating wire and the silicone electric wire that, in this case, works exclusively as a return conductor.
The bipolar cable thus obtained can be possibly clad, by means of special braiding machines, in a multi-wire metal braiding that guarantees a high mechanical protection, a higher temperature dissipation (therefore raising the thermic exchange with the final application) and secures the earthing contact.
Moreover, Calorflex particular technology allows to manufacture resistances with differentiated powers on the heating segments, or with non heating segments distributed on the whole length of the resistance.
