Standards
-
ProductCEI 20-68; HD 620; IEC 60502-2
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).
- 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).
- Outer sheath: extruded polyethylene (PE) compound. Colour: red.
Functional characteristics
- Rated voltages U0/U: 18/30 kV
- Max. operating temperature of conductor: 90°C
- Max. short circuit temperature of conductor: 250°C (max 5s)
- Max. short circuit temperature of screen: 150°C
- Min. installation temperature: -25°C
- Max. tensile strength on the conductor during installation: 50 N/mm2
- Min. bending radius during installation: 21 Dphase
