Standart: EN 50 397-1
Description: Al conductors • XLPE covering
Application:
Conductors with XLPE covered for overhead lines, are designed for transfer and distribution of electrical power in overhead electrical networks with nominal voltage to Uo/U/Um 12/20/24 kV and frequency 50 Hz. The main characteristics of overhead lines with XLPE covered conductors are low susceptibility to operational failures when conductors strike against each other or when a tree is temporarily leaning on the line. Also the space in the terrain required for the line is narrower, specially in case of parallel lines.
