Power flexible multicore cables

Power flexible multicore cables

TU U 31.3-31850229-008-2004
IEC 60502-1 (1998-11)

 

Application

GNV-M (-) 0.66 kV

Cables are designated to connect movable devices or electric equipment to power systems at ambient temperature from -40 C to +50 C.

 

Construction

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

Insulation
Polyvinylchloride (PVC) compound.

Oversheath
Polyvinylchloride (PVC) compound.

Technical characteristics

Number and nominal conductors cross-section:

Number of conductors Nominal conductors cross-section, mm
7; 10; 12; 14; 16; 19; 24; 27; 30; 33; 37 1.0 — 4.0
7; 10 6.0

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 120% 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.

Manufactured cable length: min. 150 m.

Cables of variable lengths may be delivered upon request.

Protractedly permissible temperature for the conductors heating: 70 C.

Cables are flame retardant with a single laying.

Cables are resistant to sun radiation.

Cables are resistant to lubricating oils and diesel fuel.

Cables must resist repetitive π/2 radian bends at min. 49 H tensile force at ambient temperature (25±10)C:

  • nominal overall diameter of cable from 10 to 25 mm – 9000 bend cycles;
  • nominal overall diameter of cable over 25 mm – 6000 bend cycles.

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

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

Guarantee period: 12 months from the commissioning date but not later than 18 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.
