SAH-20//SAX SAHv-20

Uo/U - 2/20 kV FN KI 02.004/06 / / SFS 5791/94
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
