General features (also available )
We are the only world manufacturer of water cooled cables for electric furnace
AC and DC in the CONCENTRIC, ROPE and STAR LAY technology. As a result, choosing
between this different type of cables we are able to give the customers the better
solution to meet any productive demands.
We design and build water cooled cables with section up to 7000 mm² and lengths more
than 15 metres, with a maximum current intensity of 4,5 A/mm² and a bending radius of 5
times the internal diameter of the hose rubber. |

» Rubber hose
The water cooled cables rubber hose is normally exposed to a considerable
hard-wearing mechanical stress, traction and torsion and a terrible thermal
shock during the furnace movements. So it's accurately realized using
a synthetic auto-extinguishable rubber reinforced with internal nylon
layers and covered with a thermal protection.
The FORNOFLEX type is a special tube made with a particular anti-abrasive
vulcanised external strip that doesn’t need the BUMPER.
Several kinds of protection, made of silicon or aluminium sheath, can
be added to this. |

Copper conductor
The conductor is made of electrolytic refined tough pitch copper
and has a diameter from 0,5 (Rope and Star lay) to 1,8 mm. (Concentric
lay) according to the application. In particular, in the Star lay
cables, we use a tinned copper elementary wire to avoid the copper
oxidation and get a longer medium life of the cables. |

Copper terminals
Made of the same material as the copper conductor, they are connected to it
by low temperature brazing. Their dimension are upon customers request with
eventually a silvered contact surfaces. |

GMR
Is the fundamental parameter to minimize the power loss and the reactance of
the transformer secondary circuit. Once again, thank to our CONCENTRIC, ROPE
and STAR lay technology, we can provide a product that grant the better
energetic performance. |
