Automobile flexible cables

KGVVA, KGVVAM under Belarus quality requirements 16-705.259-82

APPLICATION

Automobile flexible cables are designed for connection of electric equipment to automobile DC electric main with nominal voltage up to 28V.

DESIGN

CONDUCTOR — copper multiwire.
INSULATION — PVC. Insulated cores should be of different colors. KGVVAM insulation is thin.
STRAND — insulated cores are twisted. Parallel core laying of twin cables is allowed.
SHEATH — PVC. Talc is spread on insulated cores when imposing a sheath.
NUMBER OF CONDUCTORS — 2, 3, 4, 7, 10, 12, 14.
NOMINAL CROSS-SECTION, mm²: 0,75; 1,0; 1,5.

TECHNICAL DATA

Сonductor DC resistance at 20°С should not be more than:

  • 24,7 МОhm for 0.75mm² cross-section;
  • 18,5 МОhm for 1,0mm² cross-section;
  • 12,7 МОhm for 1,5mm² cross-section.

The cables with two or three cores withstand not less than 15000 bending cycles; the cables with more than three cores withstand not less than 10000 bending cycles.
Operational temperature range is from -40ºС to +70ºС.
Wires resist to fuels and lubricants oils: mineral oils, gasoline and diesel fuel.
Cables do not extend combustion at a single laying.
90% сable resource corresponds to 450 thousand car mileage in kilometers.
The delivery length should not be less than 100 meters, 20m and more wire pieces are possible to deliver but not more than 20 % of total length of batch.
The minimum operating time of cables is 20000 hours.
Average service life of cables is 10 years.
