MV ABC Wire(SANS 1713)

Application
Suitable for aerial installation and for public power distribution networks.

Standards
SANS 1713— Electric cables -Medium voltage aerial bundled conductors for voltages from 3.8/6.6 kV to 19/33 kV. 

Construction:
Conductor: Aluminum, circular stranded and compacted.
Conductor Screening: Extruded thermosetting semi-conductor layer.
Insulation: XLPE thermosetting material.
Insulation Screening: Semi conducting screen: Extruded thermosetting semi-conducting layer, applied under a swellable semi-conducting tape for watertightness.
Metal screen: Plain soft copper wire and / or copper tape applied helically, or aluminum tape applied longitudinally bonded to the outer PE sheath.
Outer sheath: Extruded black PE sheath, or PVC upon specific customer requirements.
Steel Messenger: 50 or 70 mm² galvanized steel stranded wires, covered with black PE, or PVC upon specific customer requirements.
