Power flexible cables

�GNV (����) 0.66 kV

Cables are designated to connect movable devices or electric equipment to power systems at bending’s with radius no less 8 diameters, at ambient temperature from -40 �C to +50 �C.

Conductors
Multicore copper round stranded conductors (equal to or more than class 5 in accordance with GOST 22483-77).

Insulation
Insulation is made from polyvinylchloride (PVC) compound

Oversheath
Oversheath is made from polyvinylchloride (PVC) compound

�GNV �GNV	1, 2, 3, 4 5	1.0 — 240 1.0 — 120

Conductors resistance of conductors calculated for 1 km at 20 �C complies:

• at acceptance and delivery - with GOST 22483-77;
• for operational and storage period – no more 110% from normalized at acceptance and delivery of cable.

Insulation resistance calculated for 1 km at 20 �C is at least:

• at acceptance and delivery – 50 MOhm;
• for operational and storage period – 0.05 MOhm;

Cables endure AC voltage test and 50 Hz frequency during 5 minutes as follows:

• 2.5 kV - at acceptance and delivery for multicore cables without immersing in water, and for single-core cables with immersing in water;
• 1.5 kV - for operational and storage period.

Cables with conductor cross-section area 4 mm� and above must resist to repetitive bends through a system of rollers under current loading and endure at least 30000 bend cycles.

Cables are flame retardant with a single laying.

Cables are resistant to sun radiation.

Cables are resistant to lubricating oils and diesel fuel.

Manufactured cable length:

• manufactured cable length must be min. 150 m for cables with main conductor cross-section up to 35 mm� included;
• manufactured cable length must be min. 125 m for cables with main conductor cross-section up to 50 mm� and above.

Stretching force on a cable for 1 mm� of the total conductors area is max. 19.6 H.

Protractedly permissible temperature for the conductors heating: 70 �C.

Minimum permissible bending radius of the cable at installation and routing must equal to min. 8 outer diameters of the cable.

Guarantee period: 6 months from the commissioning date but not later than 12 months as from the date of production.

The manufacturer can ensure compliance of cable quality with requirements of current technical specification, provided all terms of transportation, storage, installation and use have been observed.

Service life: min. 4 years.

All products are certified.
