NA2XSEBY Medium Voltage Three Core Cable

Details

Overview

NA2XSEBY medium voltage power cable, AL/XLPE/STA/PVC Cable

NA2XSEBY(AL/XPLE/STA/PVC )medium voltage power cable with stranded compacted aluminium conductor is composed of aluminium conductor (AL), cross-linked polyethylene insulation (XPLE), Copper tape or copper wire screen, steel tape armoring for mechanical protection and a polyvinyl chloride sheath (PVC). NA2XSEBY cables are suitable for for distribution networks,in fixed installation outdoors in cable ducts or directly in the ground, it widely used in transformer stations, electric power plants and industrial plants.
