The NYY cable range includes NYY-J and NYY-O cables

These are widely used European power and control cables designed for fixed wiring installation with a voltage rating of 600/1000V. 

They can be safely deployed in most applications where mechanical stresses are not anticipated – indoors, outdoors, direct burial underground, 

in concrete, or submerged in water. 

When NYY cables are required to comply with the UK wiring regulations BS7671 for burial in the ground, they require installation in a conduit or 

duct to provide protection against mechanical damage. 

They are not suitable for installation in concrete which is shaken, vibrated or compressed.

The construction of the NYY-O differs from the NYY-J in that it doesn't have a green/yellow earth wire.

These black NYY cables have a UV-stabilised outersheath making them suitable for direct exposure to sunlight. They have an operating temperature 

range of -15℃ to +70℃ when fixed and -5℃ to +50℃ when flexed. 

NYY-J & NYY-O CABLE SELECTION

As a leading NYY supplier and supplier of fixed installation power supply cables manufactured to various European and national standards, 

our technical engineers have vast experience of advising on cable selection for NYY-J and NYY-O as well as their aluminium conductor counterparts 

NAYY-J and NAYY-O. For technical support, please see the NYY specification datasheet or call us to discuss your specific project requirements.
