Application
These power cables are the new generation of cables forpublic medium voltage distribution–HTA. Used for direct installation on the ground, water, outdoors, indoors and in cable ducts.
Description
The cable is made of 1 or 3 bunched cores.
The longitudinal seal is provided by a swelling powder.
