HALOGEN FREE AND FLAME RETARDENT FLEXIBLE CABLES (HFFR)

Once the conductors are chosen from bright electrolytic grade copper, they are annealed and packed together.
A specially formulated grade of halogen-free flame retardant (HFFR) compound is utilised to insulate the bunched conductors. In the event of a fire, the insulation does not melt or drip. There is very little, translucent smoke released. Evacuation is convenient, and the people caught in the fire do not suffocate.
The generic designation “KVVS WIRES AND CABLES HFFR” 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
