Бүтээгдэхүүний дэлгэрэнгүй тайлбар
APPLICATION：
Aerial bundled cables are mainly used for secondary overhead lines on poles or as feeders
to residential premises. The cable as a new-type aerial cable is used for transmitting electric power overhead, extensively used in rebuilding of urban and forest region electrified wire netting. It improves the safety and reliance of electrified wire netting.
STANDARD：
Basic design to IEC 60502 / AS / NZS 3599-1 standards
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.
