copper or aluminum, multi-wire, compacted, and conforming to Class 2 as per IEC 60228. Conductors with cross-section 1000-2500 mm2 are made of 5 sector-segments


made of electrically conductive XLPE


made of XLPE


made of electrically conductive XLPE


made of electrically conductive water-blocking tapes


copper wires layer covered by spiral copper screen

Notes:

- Copper screen cross area depends on short-circuit current magnitude and flow time and shall be specified at the time of order placing

- As per customer’s request, copper-wire screen may be equipped with fiber-optic temperature modules


made of water-blocking tapes


made of high density polyethylene, cable grade N(А)2XS(F)2Y+ has reinforced sheath made of high density polyethylene

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 are designed to be in ground in dry soils (sand, sand-clay and normal soils with moisture content less than 14%).

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

- 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
