ARE4H5EX 12/20kV 3x1x185 SK1

Description

Helically bundled tripolar cables with aluminium conductor, reduced thickness XLPE insulation, aluminium tape screen, shock resistant PE outer sheath.

Application:

Suitable for fixed installation indoor or outdoor, laying in air or directly or indirectly buried. The special outer sheath provides an excellent protection against impacts and mechanical stress. Cables shock resistance has been evaluated by the abrasion and impact tests included in CEI 20-68 standard. This type of cable can be directly buried, without additional protections, because it is comparable to an armoured cable.

Construction

• Conductor: stranded, compacted, round aluminium – Cl. 2 (IEC 60228).
