Cables are intended for electrical energy transmission and distribution in solidly grounded neutral systems with rated voltage 190/330 kV AC, 3ph, frequency 50 Hz, directly connected with overhead lines or without it, on paths with unlimited level difference. Cable is designed for fixed installation in electrical systems of public and industrial premises with corrosive gases exposure limits, as well as for open-air and in-ground installation.

Cable climatic version placement category 1 and 2 as per GOST 15150-69

Working temperature range: -60°С to +50°С

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 core

- 105°С at overload (max 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 3 years (from the date of cable commissioning)

Service life is at least 30 years
