NF C 33-226 Cables/FR-N20XA8E & FR-N30XA8E -R/AR –Al/XLPE/HDPE Hta Cis Direct Burial Aluminum Power
Design:
The cable is made of 1 or 3 bunched cores.
Aluminium screen is made to ground short-circuit currents of EdF network, up to 1000 A for 1 s. for underground networks.
Application:
NF C 33-226 cables are the new generation of cables for public power distribution network 12/20 kV. They are AD7 following NF C 13-200 with a water pressure < 0,2 bar.
Options:
NF C 33-226 cables can be manufactured with the following options:
• Copper conductor
• Other voltage
• Other section
• Grounding conductor
• Thicker aluminium screen
• Bunch
Re-enforced
