12.7/22KV ABC Cable
12.7/22kV XLPE or HDPE insulated aerial cable
Aluminum Electrical XlPE/PVC/PE Insulated Overhead Cable LV MV Al Service Drop 12.7/22kV ABC Cable
APPLICATION：
It is preferred to use of ABC cables instead of uninsulated conductors at low voltage networks. ABC cables are especially used at areas where the cost of underground networks is expensive and also for electrification of rural areas like villages.Bundles can include one or two additional conductors for public lighting and control pair.
