1-conductor: rope of aluminium alloy, AlMgSi
2-insulation: XLPE, resistant to weathering factors
2-insulation: XLPE, resistant to weathering factors
keyboard_arrow_downApplication
For overhead insulated distributive networks of nominal voltages 6/10 kV and 12/20 kV. Especially suitable solution for construction of overhead networks in forest areas due to reduced width of cutting through forest and lower cost of construction and maintenance as related to the networks with bare conductors.
