ProductNF C33-209
Application
NF C 33-209 service bundled conductors are used for tributary networks of power buildings and their internal networks.
Characteristics
The bundled conductor cables have aluminum (or copper ) conductors, insulated with XLPE, they have good durability and thermal resistance.
Some other important cable characteristics are :
- Ultraviolet radiation resistance,
- Ozone resistance,
- High dielectric strength,
- Light and easy to handle.
Installation
The NF C 11-201 standard´s procedures determine the installation procedures for low voltage overhead lines.
These cables are NOT ALLOWED to be buried, even in conduits.
Electrical characteristics
- Rated voltage : 0.6/1 kV
- Test voltage : 4 kV AC
- Resistance to voltage surges : 1.2/50µs with a positive or negative polarity and a peak value of 20 kV.
