NF C33-226 Al/XLPE/PE 12/20kV Cable

The NF-C33-226 is a commonly specified French Normes cable, designed for primary and secondary power distribution. This Medium Voltage cable has a rated voltage of 12/20kV (24kV). 

NF-C33-226 Cable Specification

Available as both a single core cable and 3x1 (trefoil) cable, the NF-C33-226 MV cable can be installed in ducts, buried directly, or in free air. It can be supplied with sheath colours depending on the installation specification: 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.

Manufactured in accordance with HD620 standard, the Aluminium NF-C33-226 is insulated with XLPE to provide a maximum conductor operating temperature of +90oC. A grooved Insulation Screen, easily peeled away for speed of termination sits below a metallic screen, with tightness powders applied. to prevent water ingress. The polyethylene sheathing offers a robust outer layer of environmental protection, resilient against tearing and abrasions and offers good water resistance. 

NF-C33-226 Cable Datasheet

The technical datasheet lists single core cables up to and including 1200mm2, whilst the trefoil formation states sizes to 400mm2. Where alternative sizes are required, please speak to the team. Current Carrying Capacity and Maximum Tensile Strength are also detailed, but additional electrical characteristics can be provided to support your installation specification.

The NF C33-226 20kV cable is 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 are also available. Additional voltage ratings are available upon request.
