CAAI 0,6/1 kV 3x70+NA70 mm2
Description
Description
Application:
For urban and rural overhead secundary distribution networks, with voltages up to 1000 V.
Construction:
1. Conductor: Aluminium 1350, class 2.
2. Insulation: Cross linked polyethylene XLPE.
3. Insulated neutral messenger: AAAC - All Alloy Aluminium 6201 - XLPE.
Main characteristics:
Decreases energy theft, cross-linked polyethylene allows more current capacity and high insulation resistance, lower inductive reactance than with bare conductors, used in overhead distribution lines. Increased safety due to its mechanical strength and toughness of the insulation. Insulators are not necessary for installation. Resistance to abrasion, weather and sunlight.
Cross section:
From 16 mm2 up to 240 mm2.
Marking:
CAAI 0,6/1 kV - (Nb. cores x section) + NA (insul. neutral mesen. section) - Year - Sequential length.
Packing:
Non returnable wooden reels.
Colour:
Black, see core identification.
