TOXFREE® N2XH FLEX, best-in-class power distribution cable for Data Centres
Cables like TOXFREE® N2XH Flex are at the heart of AI and Data Centre infrastructure. They carry the energy needed to power racks, cooling, lighting, emergency systems, CPUs, GPUs, and most other equipment in a Data Centre (DC). It is critical that your DC is built with high quality cables, enhanced with specific properties, and our N2XH Flex was especially designed to perform in DCs, with the highest level of protection for the valuable people and equipment inside.
Data Centres require a significant amount of energy to maintain a continuous power supply with minimal interruptions. These facilities must ensure that they are as energy efficient as possible, particularly as their energy requirements are expected to increase considerably in the near future. Currently, this is being measured through a metric known as Power Usage Efficiency (PUE). Cables are the arteries that guarantee the power supply, and it is essential that these cables are as energy-efficient as possible, ensuring seamless service and providing maximum infrastructure performance.
THE KEY PROPERTIES OF N2XH FLEX
The four key properties are: A B2ca CPR fire safety rating, zero halogens, high flexibility, and UV protection. We complete a great product, with a sustainable, top-of-the-line service to match the specific needs of your projects.
A CABLE WITH THE HIGHEST CPR FIRE RATING: B2ca
To manufacture great quality cables, we decided to also manufacture our own compounds that make up each layer of the cable. With this, we have achieved the highest possible CPR rating B2ca (s1a, d1, a1) that fully complies and exceeds Cca (s1a, d1, a1), and set it as a standard in our product line. Here is a video that explains, in detail, how CPR and its scale works.

A LSZH CABLE: LOW SMOKE ZERO HALOGENS
In a fire, people are mostly harmed by breathing toxic smoke, and not the fire itself. To address that, we designed our N2XH Flex with a zero halogen outer sheath. When burning, the gases emitted will not be toxic for humans, and non corroding to the electronic equipment.
AN EXTRA-FLEXIBLE CABLE
DCs are electrically complex buildings. Dozens of kilometers of cable pass through rooms, roofs, floors, and within walls. Our highly flexible N2XH Flex has a significantly lower bending radius that provides: lower installation times, easier installation, maintenance, and replacement, and less space is required to cable all through the building.
A CABLE WITH UV PROTECTION
Even though DCs are very closed buildings, there are several kilometers of cable running on their roofs and outside the building. Without UV protection, cables that are in constant exposure to the sun will have significantly lower life expectancy than a cable with UV protection. We manufacture our N2XH Flex with a top-of-the-line UV protection, at the same level of cables made for solar installations. This will ensure a long life for your power distribution.
