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.
