NF C 33-226 12/20 (24) kV aerial bunched cable
MV insulated aerial bunched cables NF C 33-226
StandardsNational : NF C 33-226; NF C 33-226
NF C 33-226 cables are the new generation of cables for public power distribution network 12/20 kV.
The cable is made of 3 bunched cores with a messenger.
Aluminium screen is made to ground short-circuit currents of EdF network, up to 1000 A for 1 s. for underground networks.
Calculated from IEC 60949, Permissible short circuit current is applicable for the conductor during 1s.
Example NEXANS - plant number- BGN5 NF C 33226 int. designation- section - Al - 12/20 (24) kV - year - month - installation guide type - G sheath thickness - SC semi-conductor thickness - EC screen thickness - C2 RT- installation temperature - Eca
Core identification: 1, 2, 3 helix-wise.
The marking is metric over one core sheath, as well as a tracing mark.
