0.66 kV

Cables are designated for fixed connection to electric devices at nominal AC voltage up to 660 V and 100 Hz or DC voltage 1000 V.

Cables are used indoors, in channels, tunnels, underground cable lines, including corrosive conditions, provided cables are not exposed to mechanical damages.

Cables with «ng» designation are designated for fixed connection to electric devices at nominal AC voltage up to 660 V and 100 Hz or DC voltage 1000 V for laying in cable constructions and premises requiring fire safety of cable circuits in bundled layings. Cables can be laid outdoors, provided cables are not exposed to mechanical damages and direct sun.

Cables are intended for operation in conditions requiring fire safety when laid in bundles and low smoke and gas emission at burning (in power, tube and nuclear stations, skyscrapers and public places).

Cables are intended for laying where required special fire-prevention measures for the protection of people and material values.

Cables are designated at ambient temperature from -40 C up to +50 C and relative humidity up to 98 % at temperature at temperature to 35 C.

 

Construction

Conductors
Copper or aluminum round single-wire conductors (class 1 in accordance with GOST 22483-77).

Insulation
Insulation is made from polyvinylchloride (PVC) compound.

Oversheath
Oversheath is made from polyvinylchloride (PVC) compound.

Separation layer
Separation layer is made from polyvinylchloride (PVC) compound.

Screen for VVGEng, AVVGEng, KVVGEngLS, AKVVGEngLS cables
Screen is made from aluminum foil. Copper wire is laid under aluminum foil.

Covering «BbSHv»
- armour is made from galvanized steel tapes;
- polyvinylchloride (PVC) compound is applied over wrapping.

1.0; 1.5 10
2.5 — 4.0 9
6.0 — 10.0 6

Electric resistance of conductors to DC complies with GOST 22483-77.

Cables endure variable stress level tests with rated frequency of 50 Hz for 5 minutes as follows:

  • 2500 V – at acceptance and delivery;
  • 1500 V – for operational and storage period.

Cables are bending – resistant during installation.

Protractedly permissible temperature for the conductors heating: 70 C.

Minimal temperature of cable laying without pre-heating: -15 C.

Tensile stress at cables at laying and installation must not exceed 4 kgf/mm for copper conductors, and not exceed 2 kgf/mm - for aluminum conductors.

Minimum permissible bending radius of the cable at installation and routing must equal to min. 10 outer diameters of the cable for armoured cables, and min. 6 outer diameters of the cable – for unarmoured cables.

Minimum permissible bending radius of unarmoured cables at installation at ambient temperature min. 0 C must equal to min.:

  • 3 diameters of the cable for cables with outer diameters up to 10 mm included;
  • 4 diameters of the cable for cables with outer diameters over 10 and up to 25 mm included.

Cables have flame-retarding ability when laid in bundles in accordance with DSTU 4237 – 3 – 22 (category A).

Manufactured cable length for cables: min. 150 m.

Guarantee period: 3 years from the commissioning date.

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: generally min. 15 years; and min. 25 years at indoor cable installation, laying in tunnels and channels.

All products are certified.
