Description

Standards

Product

CEI 20-68; HD 620; IEC 60502-2

Description

Single core cables with aluminium conductor, reduced thickness XLPE insulation, aluminium tape screen, double shock resistant PE sheath.

Application:

Suitable for fixed installation indoor or outdoor, laying in air or directly or indirectly buried. The two special sheaths provide 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).
Conductor screen: extruded semiconducting compound.
Insulation: extruded polyethylene (XLPE) compound.
Insulation screen: extruded semiconducting compound – fully bonded.
Longitudinal watertightness: semiconducting water blocking tape.
Screen and radial watertightness: aluminium tape longitudinally applied (nominal thickness: 0,2 mm).
First sheath: extruded polyethylene (PE) compound.
Second sheath: extruded polyethylene (PE) compound. Colour: red.
