N2XSH N2XS(F)H & N2XS(FL)H Cables

Our Medium Voltage cable portfolio includes the N2SXH Low Smoke Zero Halogen Cable in 10kV, 15kV, 20kV, and 30kV. It is a UV-resistant cable available with optional single and dual waterblocking layers.

N2XSH Cable Applications

N2XSH power distribution cables are used for private grid networks across a wide range of industries including data centres and life sciences new build sites. They are available as either single core or three core variants (where the multicore is referred to as N2XSEH and where the individual cores are screened).

Installation of these unarmoured cables is usually in cable ducts - as three single cores or in triplex formation (3x1) - use of the three-core variant is much less common but is available.

This combination of LSZH insulation and sheathing with constructional layers that are more typically found on the N2XSY PVC and N2XS2Y PE cables gives N2XSH, N2XS(F)H and N2XS(FL)H cables the flexibility to be installed both internally or externally. 

N2XSH Cable Manufacturer Standards

Manufactured generally in accordance with IEC 60502-2, these N2XSH (and N2XSFH / N2XSFLH variants) are flame retardant to IEC/EN 60332-1-2 and low smoke zero halogen to IEC/EN 61034-1/2 and IEC/EN 60754-1/2 making them suitable for internal installations and also UV resistant so they can be used externally too. In practice, this means they can be run from outside to inside in a CPR Compliant installation without the need to joint or change cables at the point of entry.

N2XSFH & N2XSFLH Cable Specification

Installation design and environmental site specifics will determine the cable specification. Where appropriate, additional waterblocking may be required to offer protection against water ingress. Longitudinal waterblocking (the N2XS(F)H cable) and dual longitudinal and radial waterblocking (the N2XS(FL)H cable) can provide such measures.

As before, these cables are usually installed as 3x single cores / triplex, but where the 3-core cable is used it is referred to as N2XSE(F)H and N2XSE(FL)H respectively - with each of the conductors being individually screened.

These cables are commonly installed in cable ducts, providing them with additional mechanical protection. Where the N2XS(F)H and N2XS(FL)H versions are particularly important is in the event the ducts become waterlogged. The single and dual waterblocked layers are commonly a water-swellable tape and an additional water-swellable powder, unless destined for clean environments where powder-free cable construction is stipulated and when two tapes are used. These additional layers prevent any ingress of water from reaching the insulation layer and potentially impeding the performance of the underlying conductor. 

 

N2XSH Cable Voltage Rating

Cable datasheets are provided as standard for N2XSH cables. N2XSH cables are designed with the European market in mind, where fixed installation and direct burial cables can be unarmoured (unlike the BS6622 and BS7835) and they are often for the connection of critical infrastructure and equipment.

Where other voltages are required, please speak to the team and they will be happy to provide the datasheets and information needed.

The N2XSH, N2XS(F)H and N2XS(FL)H is available in 3-core variants at voltage ratings including 6/10kV, 8.7/15kV, 12/20kV and 18/30kV, upon request.
