Constant Power Heating Cable

Potenza_Costante_6 Potenza_Costante_5 Potenza_Costante_4 Potenza_Costante_3 Potenza_Costante_2 Potenza_Costante_1


The main feature of this type of cable is an uniform specific
charge on its entire length, granting the possibility to manage
the specific power independently from the required cable
Constant power cables are manufactured winding the
heating wire to the phase and neutral wires on which an antilaceration
silicone is extruded.
A 10mm section of the insulation is removed each 500mm
creating the electrical contact, the external silicone is
transparent to enable the detection of the cut points. The
product is provided wound in coils, to be cut and finished
according to the specific needs with the kit of accessories,
which can be provided with the product.
A special metal braid can be added on the external insulation
to protect the cable from mechanical stress and improve its
thermal distribution. It can act as well as grounding.
