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.
The series heating cable CDLx is usually installed in domestic and industrial refrigeration and air conditioning appliances. The vulcanized joint and the built in cold part provide the cable with a waterproof structure, so as to allow its installation directly inside the pipelines. It is supplied already cut to measure and ready to use: its length cannot be shortened by the end user.
