NYY(80°) 0,6/1 kV 3-1x400 mm2

Description

Description

Application:

General use as power cable. In low voltage distribution networks, industrial installations, buildings and operating centers. For fixed installations, in indoor areas (trays, ducts), in underground ducts or buried direct in ground, in dry or wet locations.

Construction:

1. Conductor: Soft copper, class 1 or class 2.

2. Insulation: Compound polyvinyl chloride PVC.

3. Outer sheath: Compound polyvinyl chloride PVC.

4. Tape: Polyester tape.

Main characteristics:

Good electrical and mechanical properties. The PVC outer sheath provides an adequate resistance to grease, oils and abrasion. better dissipation of heat allowing a higher current capacity. Flame retardant.

Marking:

INDECO S.A. NYY(80º) 0,6/1 kV (2 or 3)-1x Section - Year - Sequential length.

Packing:

Non returnable wooden reels.

Colour:

Insulation: White.

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

Calculation of Current Condition: Copper Conductor Double or Triple L.V.; 80°C

CURRENT CAPACITY VALUES AND CURRENT CALCULATION CONDITIONS BASED ON IEC 60364-5-52:2009 :

TABLE B.52.4 (METHOD D1: Buried ducts in contact).
TABLE B.52.4 (METHOD D2: Buried in contact).
TABLE B.52.10 (METHOD F: Air in flat formation and in contact).
TABLE B.52.10 (METHOD F: Air in tringular formation).

The cited values ​​were corrected with a correction factor for the maximum conductor temperature at 80°C.
Maximum conductor temperature : 80°C.
Ambient air temperature : 30°C.
Ground temperature : 20°C.
Depth of laying up to: 0,7 m.
Thermal resistivity of soil : 2,5 K.m/W.
