Powering Mission-Critical Infrastructure
Data centres are at the heart of the modern digital economy, relying on continuous power to operate servers, cooling systems, and emergency backup systems. Our cables are trusted across the whole power distribution chain:
- From grid connections to internal server rooms
- Linking substations with generators and transformers
- Delivering LV power to fire systems, HVAC, and IT servers
- Facilitating renewable energy integration (solar & wind)
With minimal tolerance for downtime, we help data centre operators maintain operational reliability while meeting evolving energy efficiency and carbon reduction targets.
How Are Cables Clasified Under CPR?
Under CPR regulations, cables have to be rigorously tested and are then classified based on several critical factors. To find out more, read our full guide on The regulation of CPR rated cables.
Low Smoke Zero Halogen (LSZH) Cables
Our LSZH range supports internal cabling where safety and equipment protection are critical. These cables minimise the emission of toxic gases and smoke during fire incidents, helping protect both life and sensitive data infrastructure.
N2XH Cables (LSZH)
N2XH cables are unarmoured power and control cables designed for energy supply in fixed installations. They can be installed Indoors, where the risk of mechanical damage is low, Outdoors, in open air and Underground, with appropriate external protection. N2XH Cable can also be installed In dry and damp environments, under plaster, in walls, masonry, and concrete
Breakdown of N2XH cable designation:
N - Cable Standard from Gernmany (VDE)
2X - XLPE insulation (cross-linked polyethylene)
H - Halogen-free sheath (LSZH - Low Smoke Zero Halogen)
Applications
- Commercial buildings (Shopping malls, offices)
- Public buildings (Schools, Hospitals, Airports, Stations)
- Data Centers and Server Rooms
- Industrial facilities
- High-density living areas (e.g Apartment Complexes)
- Emergency lighting and power systems
- Note: These cables must not be directly buried without external protection against mechanical stress or water.
