XLPE insulated and PVC compound sheathed, screened power cables with copper or aluminum cores

XLPE insulated and low-flammable PVC compound sheathed, screened power cables with copper or aluminum cores

copper or aluminum, single- or multi-wire, round and sectoral shape, conforming to Class 1 or 2 as per GOST 22483

made of silane cross-linked PE

Insulated cores of multicore cables have distinguishing color

Neutral cores insulation is blue

Grounding core insulation is two-color (yellow and green)

insulated cores of two-, three-, four- and five-core cables are twisted with each other; cores of two-, three- and five-core cables are of the same cross-section, in four-core cables all the cores are of the same cross-section or one core (grounding or neutral) has smaller cross-section

PVC & low-flammable PVC compound for cables

copper tape or copper wires lapping

PVC compound & low-flammable PVC compound

Cables are intended for electrical energy transmission and distribution in stationary installations with high degree of electrical protection with rated voltage 0.66 and 1kV, 50 Hz

Cables climatic category is NF and T, placement category 1 & 5 as per GOST 15150-69

Operating temperature range from -50°С to +50°С

Ambient relative humidity at +35°С up to 98%

Cable lying down and installation without preheating shall be performed at temperature not lower than -15°С

Min installation bending radius:

- for single-core cables – 10 times of cable OD

- for multi-core cables – up to 7.5 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

Continuous temperature of cable conductor heating during operation is +90°С

Cable conductor allowable heating during overload is no more than +130°С

Limiting cable conductor temperature at short-circuit (max duration is 5 s) is +250°С

Guarantee service life is 5 years (since cable commissioning)

Service life is at least 30 years
