Cableworld supplies NYY and N2XH cable options, including NYY-J, N2XH and N2XH Enhanced, for projects requiring PVC or Low Smoke Zero Halogen (LSOH) constructions.
Why choose our NYY and N2XH cables?
Our range includes fixed installation power cables for building services, electrical distribution and infrastructure projects. Selecting between NYY and N2XH depends on the installation conditions, electrical requirements and specified fire performance.
NYY is a non-armoured power cable with copper conductors, PVC insulation and a PVC outer sheath. Cableworld supplies NYY-J and NYY-O constructions, which are used for fixed electrical installations indoors and outdoors, including suitable underground distribution applications.
N2XH is a non-armoured power cable featuring copper conductors, cross-linked polyethylene (XLPE) insulation and an LSOH outer sheath. It is suitable for fixed installations in buildings where reduced smoke and corrosive gas emissions are important, including commercial premises, hospitals and data centres.
Unlike NYY, standard N2XH is not suitable for direct burial or installation in water. Its intended uses include indoor installations, concrete and free air, subject to the product specification.
Cableworld also lists N2XH Enhanced, which has additional fire performance characteristics compared with standard N2XH. The relevant product specification should be checked to confirm its tested performance and suitability for the installation.
When choosing NYY power cable or N2XH power cable, check the conductor size, number of cores, voltage rating and installation method. Fire performance requirements, environmental exposure and applicable electrical standards should also inform the selection.

Popular NYY and N2XH cable questions
What is the difference between NYY and N2XH cable?
NYY cable uses PVC insulation and a PVC outer sheath, while N2XH uses XLPE insulation and an LSOH sheath.
NYY is commonly selected for suitable fixed power installations, including outdoor and underground applications. N2XH is generally used in buildings where low smoke and halogen-free materials are specified.
The correct choice depends on the installation environment and electrical requirements.
Can NYY cable be installed underground?
Yes. Cableworld's NYY cable is designed for suitable fixed installations, including direct burial.
However, the cable route, ground conditions and required mechanical protection must be considered. NYY is non-armoured, so the installation method must provide any additional protection required by the electrical design and applicable regulations.
Is N2XH cable fire resistant?
Standard N2XH cable has an LSOH construction, but this does not automatically mean it can maintain electrical circuit integrity during a fire.
Cableworld also lists N2XH Enhanced, which has additional fire performance characteristics. Whether it meets a particular fire-resistance requirement depends on the product's tested performance and applicable standards.
The relevant technical documentation should be checked before selecting cable for a circuit that must remain operational during a fire.
What is the difference between NYY-J and NYY-O cable?
NYY-J includes a green and yellow protective conductor within the cable construction.
NYY-O does not include a green and yellow protective conductor. The appropriate version depends on the circuit design and earthing arrangements.
Always confirm the required core configuration before ordering.
How do I choose the correct NYY or N2XH power cable?
Start with the circuit's voltage and current requirements, conductor size and number of cores.
For outdoor or underground installations, check the cable's environmental suitability and mechanical protection requirements. For buildings with specific fire safety requirements, consider whether standard LSOH construction or a cable with verified circuit integrity performance is needed.
