Applications

Flexible power and control cable for fixed installations. To be used in locations where concentration of people is high: hospitals, malls, offices, classrooms, auditoriums, etc.

It can be installed in free air, in ducts or cable trays. In small sizes, it is used as control cable for the inner part in cabinets.

Construction: Singlecore or multicore copper conductor from 3 to 5 cores.

Conductor: Class 5 flexible copper conductor according to IEC 60228.

Insulation: Crosslinked Polyethylene (XLPE) with excellent electrical properties, good resistance to ozone and chemical agents. Cores identification by colors.

Oversheath: Low Smoke Hologen free compound. Low fire hazard thermoplastic, halogen free, low smoke emission, flame and fire retardant, resistant to weather and UV radiation. Other colors upon request. 

Design Alternatives

FREETOX-FLEX-RAT: Resistant to rodent attack.

FREETOX-FLEX-BLIND: Shielded with copper tape.

FREETOX-FLEX-BLIND-TZ: Shielded with a tinned copper braid.

Other sizes or construction different to those included in the catalog.

Current carrying capacities based on table N°4.4 according to RIC N°4, They are applied for installations where ducts and cables are not directly exposed to solar radiation.

(3) direct current buried at 20°C: Sheathed, single conductor or multi conductor cables (Three conductors with load) installed directly buried. Installation Method D2 according to RIC N°4.

(4) current in buried duct at 20°C: Single conductor or multi conductor cables (three conductors with load) installed in buried ducts. Installation Method D1 according to RIC N°4.

(5) duct current at 30°C: Up to three single conductors or multi conductor cables (three conductors with load) installed in ducts or trays attached to walls. Installation Method B1 and B2 according to RIC N°4.

(6) air current at 30°C: Multiconductor cables (Three conductors with load) installed freely in the air, in conductor ladders or in conductor baskets or in perforated trays. Installation Method E according to RIC N°4. Single conductor cables: Three conductors with load, in contact and in a flat arrangement, installed freely in the air, on conductor ladders or in conductor baskets or in perforated trays. Installation Method  F according to RIC N°4.

For buried installations, a depth of 0,7 meters and a thermal resistivity of the soil of 1 K*m/W.

Current capacity correction factors must be considered according to the specific installation conditions.

Values not defined as “maximum”, “max.”, “minimum” or “min.” are not normative requirements in the standard and they are indicative only.
