Feltoflex Cable Applications
The Prysmian Feltoflex®-RC (N)TMCHXOEU high-voltage flexible cable system is engineered for demanding HV power applications where tight bending radii, dynamic movement and extreme temperatures make traditional cables unsuitable. Designed for offshore platforms, wind turbines, transformers and switchgear, it delivers exceptional pliability, mechanical strength and cold-weather performance. Its flexibility reduces installation and civil engineering costs, supports movement while energised, and provides long-term reliability in dry, damp and outdoor environments — even in harsh winter conditions.
✔ Flexible high-voltage interconnections in wind turbine towers and nacelles
✔ Offshore wind substations requiring movement-tolerant HV links
✔ Transformer and switchgear connections in confined or dynamic environments
✔ Temporary or mobile high-voltage power supplies during maintenance or testing
✔ HV connections subject to vibration, torsion or repeated bending
✔ Outdoor and offshore installations exposed to UV, ozone and harsh weather
✔ Power export cables within nacelles, towers, platforms and floating structures
✔ Compact substation layouts where rigid cables are impractical
✔ Emergency or backup HV link-up during faults or grid outages
✔ Pre-assembled cable harness systems for fast installation or factory-built modules
