RETFLEX N2XY 0,6/1 kV 3x10+1x10 mm2 FB

Description

Description

Application:

General application as power cable. In low voltage distribution power networks, industrial installations, in buildings and operation stations. In fixed installations, indoor and outdoor areas (trays, gutters, staples). It can be installed in ducts, in dry or wet locations.

Construction:

1. Conductor: Flexible soft copper, class 5.

2. Insulation: Cross linked polyethylene XLPE.

3. Insulated grounding conductor: Flexible soft copper, class 5 - XLPE

4. Filler: Flexible compound polyvinyl chloride PVC (when applicable).

5. Outer sheath: Flexible compound polyvinyl chloride PVC.

Main characteristics:

Good electrical and mechanical properties. Cross-linked polyethylene insulation allows greater power capacity under any operating condition, minimum dielectric losses, high insulation resistance. The PVC outer sheath allows an adequate resistance to greases, oils, abrasion and sunlight. Flame retardant.

Cross section:

From 4 mm2 up to 300 mm2.

Marking:

INDECO S.A. RETFLEX N2XY 0,6/1 kV - Nb. Cores x section + Grounding Cond. Section - 90C - Year (- sequential length m. || sequential length m. + ) .

Packing:

Non returnable wooden reels.

Colour:

Insulation: See insulation color.

Outer sheath: Black.
