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

XLPE insulated and low-flammable PVC compound sheathed 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 compound & low-flammable PVC compound

copper tape or copper wires lapping (for cables of voltage 3kV)

PVC compound & low-flammable PVC compound

Cables are intended for electrical energy transmission and distribution in stationary installations with rated voltage 0.66, 1 and 3kV AC, 50 Hz, incl. overhead installation providing that solar radiation protection is ensured

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
