Application
NF C 33-209 Network distribution bundled conductors with neutral messenger are designed for rural and urban areas.
Some 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.
Description
The bundled conductor cables have aluminum conductors, insulated with XLPE, they have good durability and thermal resistance.
