Cables are intended for electrical energy transmission and distribution in solidly grounded neutral systems with rated voltage 64/110kV AC, 3ph, frequency 50 Hz, directly connected with overhead lines or without it, on paths with unlimited level difference. Cables used for bunched wiring as per fire hazard indexes according to GOST R 53315 shall be additionally marked with index (A) (only for cables with conductor’s cross-section area up to 630 mm2).

Cable climatic version placement category 2, 3, 4 and 5 as per GOST 15150-69.

Working temperature range:

- from -50°С to +50°С for cables with PVC sheath

- from -60°С to +50°С for cables with halogen-free polymer compound sheath

Cable lying down and installation without preheating shall be performed at temperature: not lower than -10°С.

Min installation bending radius: up to 15 times of cable’s outer diameter

Max allowable forces developed during cable pulling along the path:

- for aluminum-core cables - 30 N/mm2

- for copper-core cables - 50 N/mm2

Allowable cable core heating temperatures:

- 90°С during normal operation of cable cor

- 130°С for overload condition of cable with core cross-section area up to 800 mm2, 105° С for cables with core cross-section area over 800 mm2, (duration of overload operation shall be 100 h per year and no more than 1000 h per life cycle

- 250°С when SC current flows in the core (max duration is 5 s)

- 350°С when SC current flows in the screen (max duration is 5 s)

Guarantee period is 5 years (from the date of cable commissioning)

Service life is at least 30 years
