Overhead cables with aluminium alloy conductor and XLPE insulation, for overhead power transmission lines up to 35 kV
Cables are applied in the aerial electric networks under the voltage of 20-35 kV.
Cables are stable against the environment temperature: from -60°C to +50°C.
Cables are stable against the assembling bends and solar radiation.
Cable assembling should be executed at the environment temperature of not below than – 20°C.
Cable bending radius at the assembling and installed on the cable supports is not less than 10 wire diameters.
Insulation resistivity at the maximum permissible temperature of conductors heating is not less than 1×1012 Ohm · sm.
Insulation breakdown voltage after being in water during 1h at the temperature of + (20±5)°C is not less than 24 kV with frequency of 50 Hz.
Permissible conductors heating at the operation should not exceed +90°C in normal operation regime and +250°C –at the short-circuit current.
