Applications

Power shielded cable for fixed installations, used for connection of transformers, switchgears, GIS substations, motors, generators, feeders in distribution networks. Suitable to be installed directly buried, buried in ducts, in conduits, cable trays or in free air.

Construction: Multi-core cable.

Conductor: Compact-round stranded copper conductor. For AWG and kcmil sizes: class B according to ASTM B-3, ASTM B8 and ASTM B-496 according to requirements of ICEA S-93-639. For standard mm² sizes: class 2 according to IEC 60228.

Conductor shield: Extruded semiconducting material.

Insulation: Tree-Retardant crosslinked polyethylene (TR-XLPE)  or crosslinked polyethylene (XLPE) with excellent electrical properties, good resistance to ozone and chemical agents.

Insulation shield: Extruded semiconducting material.

Metallic shield: Copper tape applied helically in intimate contact with the underlaying semiconducting layer, 12% nominal overlap.

Ground conductor (Optional): One or three flexible bare copper conductors, class 5 according to IEC 60228, in contact with the metallic shields.

Oversheath: Low fire hazard polyolefin (LFH), flame and fire retardant, low smoke emission, resistant to weather and UV radiation. Color upon request.

Marking: NEXANS CHILE FREETOX "size" "Rated voltage" Cu XLPE "Nominal Insulation Thickness" (1) 90°C  "Manuf. order" "Date"

(1) Nominal Insulation Thickness information on marking only applies for cables according to ICEA S-93-639.

 

Design Alternatives

FREETOX-RAT: Resistant to rodent attack.

FREETOX-MAG: Armored cable with galvanized steel wires.

FREETOX-MZG: Armored cable with two flat galvanized steel tapes.

FREETOX-MAZG: Armored cable with galvanized steel wires and two flat galvanized steel  tapes.

INSTALLATION CONDITIONS FOR CURRENT CARRYING CAPACITIES_MV MULTI-CORE CABLES

(1) Current carrying capacities based on NEC/NFPA 70 for installations were ducts and cables are not directly exposed to solar radiation.

De-rating factors must be applied according to specific instalation conditions.
