The difference between the NYY-O and NYY-J

The construction of the NYY-O differs from the NYY-J in that the NYY-O doesn’t have a green/yellow earth wire. Furthermore both types can be installed in open air, underground, in water and also in brickwork and concrete with the exception of shaken, vibrated or compressed concrete.

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.
