NA2XSY 1 x (50-630) mm² 18/30 kV

Al / XLPE/ CTS / PVC
(Aluminium Conductor, XLPE Insulated, Copper Tape Screen, PVC Sheathed)
Standard Specification : IEC 60502-2

Application

For power stations and switchgear as well
as stations because of small bending radius
in confined spaces indoors. As underground
because of light weight where installation
conditions are diffcult.
