Standart: FN KI 02.004/06 // SFS 5791/94
Description: Al conductors • XLPE insulation
Application:
Conductors with XLPE insulation 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 insulation overhead 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 casse of parallel lines.
