Installing cable underground presents a different challenge than laying it along the sea bottom. On land, remoteness, tough terrain and severe climactic conditions are critical factors.
To install XLPE or paper-insulated cables we have the tools and the experience for the most isolated job. Transport is a major challenge in itself, and we often design special loading and unloading equipment. Installation in remote areas also requires complex logistics for housing, feeding and provisioning a team on the move.
Special reels and drums have been developed for easy delivery, and we are adept at handling exceptionally long lengths of cables and are expert in pulling operations. In dense urban areas, where overhead lines are an impossibility, we have developed new designs and constructions to overcome the constraints of space and meet strict safety requirements. For example, we have developed an indirectly-cooled cable system.
High and extra high voltage cables
- XLPE-insulated cables up to 400 kV
- longitudinal watertight screen area
- radial watertight by a polymer laminated sheath or a metallic sheath
- if requested with optical fibres for monitoring
