Fire Fighter-HRFR

Electrolytic copper thin strands are drawn in multiple directions to ensure consistency in resistance, dimensions, and flexibility. The drawn threads are compressed and precisely uni-laid. creating a completely round conductor as a result, allowing for a reduction in total diameter to save space in high density wiring.
PVC insulation that has been specially blended to be flame- and heat-resistant to 105 degrees is employed. The HR FR characteristic slows the spread of fire without endangering people’s safety.
The generic marking “KVVS WIRES AND CABLES FIRE FIGHTER-HRFR 105°C” is printed on the cables.
Red, yellow, green, blue, black, grey, and white. Additional colours can be requested.
90 meters, 180 meters, 270 meters, or 100 yards of packing.
