Control armoured cables

KVKbSHv, KVKbSHvng, KVKbSHvng-LS under Belarus quality requirements 5000017371.057-2010

APPLICATION

Control armoured cables are designed for fixed connecting to electric devices, apparatus, assemblages of clamps of electric distribution devices with AC nominal voltage up to 660V and frequency 100 Hz or DC voltage up to 1000V.

DESIGN

CONDUCTOR — copper multiwire, corresponds to 1 class.
INSULATION — PVC. PVC with index “ng” has low flammability; PVC with index “ng-LS” has low flammability and low gas- and smoke-emission.
STRAND — insulated conductors are twisted. Insulated conductors have tracer pair;
ZONAL INSULATION — PVC. PVC with index “ng” has low flammability; PVC with index “ng-LS” has low flammability and low gas- and smoke-emission.
ARMOURING — tined steel wires of 0,3 mm diameter. Armouring density is not less than 60%;
PROTECTIVE HOSE — PVC. PVC with index “ng” has low flammability; PVC with index “ng-LS” has low flammability and low gas- and smoke-emission.
NUMBER OF CONDUCTORS — 4, 5, 7, 10, 14, 19.
CONDUCTOR CROSS-SECTION, mm2 — 0,75; 1,0; 1,5; 2,5; 4,0; 6,0 (copper); from 2,5 to 6,0 (aluminium)

TECHNICAL DATA

Electric resistance of conductor insulation per 1 km at 20ºС should not be less than:

  • 10 МОhm for 0.75; 1,0; 1,5mm² cross-sections;
  • 9 МОhm for 2,5; 4,0mm² cross-sections;
  • 6 MOhm for 6,0mm² cross-section;

The minimum bending radius at installation and operation should not be less than fifteen maximum diameters of a cable. Cables resist to abrasion. Cables resist to cyclic heating in a salt bath.
Permissible operational temperatures is from -40˚С to +60˚С.
Maximum permissible operational temperature of conductor is +70°С.
Cable KVKbSHv does not extend combustion at a single laying. Cables KVKbSHvng and KVKbSHvng-LS do not extend combustion in bunches.
Cables are used in direct burial, duct-work, external wall, in cable channels, in corrosive environment.
The delivery length should not be less than 50 m, 3m and more cable pieces are possible to deliver but not more than 15% of total length of batch.
Average service life of a cable is 15 years;
