N2XOH-PC 0,6/1 kV 3-1x240 mm2

Description

Description

Application:

In low voltage power distribution networks. Special application in places with poor ventilation, direct application in places with public attendance high. It can be installed in ducts, ladders or cable trays, in dry, humid or wet environments.

Construction:

1. Conductor: Flexible soft copper.

2. Insulation: Cross linked polyethylene XLPE.

3. Outer sheath: Halogen free thermoplastic compound HFFR-UV.

4. Tape: Polyester tape.

Main characteristics:

The cable has excellent electric properties. The cross-linked polyethylene insulation allows a higher power capacity current under any operation conditions, lower dielectric losses, high insulation resistance. The outer sheath has the following characteristics: Fire retardant, zero emission dense smoke and halogen free. Sunlight resistance.

Cross section:

From 120 mm2 up to 300 mm2.

Marking in each phase:

INDECO BY NEXANS N2XOH-PC 0,6/1 kV - Section - Year - (- sequential length m. || sequential length m. +).

Packing:

Non returnable wooden reels.

Colour:

Insulation: Natural.

Outer sheath: Black, red and white or black, red and blue.
