Cables are intended for electrical energy transmission and distribution in stationary installations with solidly grounded and insulated neutral systems with rated voltage 6, 10, 15, 20, 30, 35kV AC, 50 Hz. Cables are designed for bunched cabling in cables works and industrial premises providing no stretching stresses occur during operation for overhead bunched cabling, as well as in cables works and premises with restrictions concerning smoke density in the case of fire for cabling in electrical systems of public and industrial premises with corrosive gases exposure limits.

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

Working temperature range: -50°С to +50°С, cables with “H” marking – from -60°С to +50°С

Cable lying down and installation without preheating shall be performed at temperature not lower than:

- for cables with PE sheath is -20°С

- for cables with PVC sheath is -15°С

Min installation bending radius:

- for three-core cables – 12 times of cable OD

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

- 130°С for SC overload (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 for copper screen in the case of single-phase short-circuit (max duration is 5 s)

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

Service life is 30 years
