NF C 33-266 Cables FR-N20XA8E-R & FR-N20XA8E-AR

The FR-N20XA8E-AR Cables (aluminium) and FR-N20XA8E-R Cables (copper) are manufactured in accordance with NF-C33-226 - a commonly specified French Normes cable, designed for primary and secondary power distribution. The Medium Voltage cables listed have a rated voltage of 12/20kV (24kV). The cables with a rated voltage of 18/30kV (36kV) are referenced with the prefix FR-N30. 

FR-N20XA8E-R, FR-N30XA8E-R and FR-N20XA8E-AR, FR-N30XA8E-AR - single core / triplex - Cable Specification 

With the copper or aluminium conductor variants of these cables available as both a single core cable and 3x1 (trefoil/triplex) cable, the FR-N20XA8E-AR and FR-N20XA8E-R MV cables at 12/20kV and the FR-N30XA8E-AR and FR-N30XA8E-R MV cables at 18/30kV  can be installed in ducts, buried directly, or in free air. 

The standard sheath colour is black, but depending on the installation specification may be changed - for instance, Red for underground connections, Grey for aerial, above/underground, and technical connections, or Black striped for identification purposes. In all cases, additional protection against mechanical stress should be considered where relevant.

These cables are insulated with XLPE to provide a maximum conductor operating temperature of +90oC. There is an aluminium tape metallic screen, with waterblocking tape wrapped underneath to prevent water ingress. The polyethylene sheathing offers a robust outer layer of environmental protection, resilient against tearing and abrasions and offering good water resistance. 

NF C 33-226 Cable Datasheet

The technical datasheets provided list single core cable sizes up to and including 800mm², whilst the trefoil / triplex formation states sizes to 400mm². Where alternative sizes are required, please speak to the team. Current Carrying Capacity along with additional electrical characteristics are provided on the datasheet, but should additional information be required, it can be provided to support your installation specification.

The FR-N20XA8E and FR-N30XA8E cables to NF C33-226 forms part of a wider portfolio of European standard MV cables, available with and without armour, and with copper or aluminium conductors, including the N2XS2Y PE cables in 10kV, 20kV and 30kV. MV cables with PVC or LSZH sheathing to IEC 60502-2 are also available, as are cables with additional mechanical protection (armour). Additional voltage ratings are available upon request.
