Advantages of the NYY-O and NYY-J

Flame retardant

Cables used to be responsible for spreading fire. The NYY-O and NYY-J are flame retardant. This means that these cables are designed in a way that it will not spread fire. Cables with these advantages are often used in buildings and at locations where people live, work and travel / move.

UV resistant*

Cables that are not UV resistant will be affected when they are exposed to direct sunlight. Only the cables with a black outer sheath have a UV-stabilised outer sheath making them suitable for direct exposure to sunlight. The outer sheath of the cable will not be harmed by the ultra-violet light which normally dries out a cable or causes cracks or bursts in the sheath. This will preserve the functionality of the cable.
