Insulation resistance calculated for 1 km at temperature 20 °C indicated at protractedly permissible temperature for the conductors heating at operational period at least 0.005 MOhm.
Cables endure AC 3.0 kV test and 50 Hz frequency during 10 minutes.
Cables are flame retardant with a single laying.
Manufactured cable length:
- manufactured cable length must be min. 450 m for cables with main conductor cross-section 2.5-16 mm²;
- manufactured cable length must be min. 300 m for cables with main conductor cross-section 25-50 mm².
Minimal temperature of cable laying without pre-heating: -15 °C.
Minimum permissible bending radius of the cable at installation and routing must equal to min. 10 outer diameters of the cable for single-core cable, and min. 7.5 outer diameters of the cable – for multicore cables.
