NA2XSEBY MV Three Core Cable 18/30kV

Applications

NA2XSEBY cables are three-core class2 stranded aluminium medium voltage cables,the cables are mainly used for:

● Indoors and in cable ducts

● Outdoors,underground

● In power supply stations

● Transformer stations

● Industrial Plants

Using steel tape armouring offers great mechanical protection, making it rigid with a large radius installation indoors and outdoors.
