Application

KVVGngLS, KVVGzngLS, KVVGEngLS, KVBbSHvngLS, AKVVGngLS, AKVVGzngLS, AKVVGEngLS, AKVBbSHvngLS
(LS, LS, LS, LS, LS, LS, LS, LS)
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 «ngLS» 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. 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 -30 C up to +50 C and relative humidity up to 98 % 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 low risk-of-fire PVC compound (low risk-of-fire and low level of smoke and gas release PVC compound).

Separation layer
Separation layer is made from low risk-of-fire PVC compound (low risk-of-fire and low level of smoke and gas release PVC compound).

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

Oversheath
Oversheath is made from low risk-of-fire PVC compound (low risk-of-fire and low level of smoke and gas release PVC compound).

Covering «BbSHv»
- armour is made from galvanized steel tapes;
- low risk-of-fire PVC compound (low risk-of-fire and low level of smoke and gas release PVC compound).

Electric resistance of conductors to DC complies with GOST 22483.

Insulation resistance calculated for 1 km at temperature 20 C:

Nominal conductor cross-section, mm Insulation resistance, MOhm, no less
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.

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.
