N2XSEBY Medium Voltage Power Cable

Details

Overview

N2XSEBY medium voltage power cable, CU/XLPE/STA/PVC Cable

N2XSEBY(CU/XPLE/STA/PVC )medium voltage power cable with stranded compacted copper conductor is composed of copper conductor (CU), cross-linked polyethylene insulation (XPLE), Copper tape or copper wire screen, steel tape armoring for mechanical protection and a polyvinyl chloride sheath (PVC). N2XSEBY 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.
