MV Aerial Bundled Cable (IEC 60502)

Application:
Aerial bundled cables are mainly used for secondary overhead lines on poles or as feeders to residential premises.

Standards:
Basic design to IEC 60502 

Construction:
Phase Conductor: Circular compacted stranded H68 aluminium to BS2627.
Conductor Screen: Extruded semi-conductive layer.
Insulation: XLPE
Insulation Screen: Extruded semi-conductive layer.
metallic Screen(optional): Copper wire screen or copper tape screen.
Separator: Semi-conductive swellable tape.
Outer Sheath: HDPE
Support Conductor: Galvanized steel wires.
Assembly: Three XLPE insulated screened cores are bundled around the galvanized steel wires in a right hand lay.

Parameter:
6.35/11 kV ABC for Overhead Distribution Lines
