Description
Standards
National : NF C 33-226; NF C 33-226Description
Usage
NF C 33-226 cables are the new generation of cables for public power distribution network 12/20 kV. They are AD8 (water pressure < 0,2 bar), AF2 and AN3 complying with NF C 13-200 standard. Sheath is anti-termite resistant.
Design
The cable is made of 1 or 3 bunched cores.
Laying condition
Burial depth : 0.80 m
Soil thermal resistivity : 1.2 °K m/W
Electrical caracteristics
Calculated from IEC 60949, permissible short circuit current is applicable for the conductor during 1s.
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 burying resistance (EDR) is ensured with an extruded polyethylene protection.
