Sudkabel EHFS, EHFSI & EHFST Terminations Benefits & Advantages

What’s the difference? Sudkabel‘s EHFS and EHFSI offer operating voltages up to 245kV and are flexible and supported options, ideal for pre-assembled site power cables or use with support insulators or surge arresters. The Sudkabel EHFST features operating voltages up to 170kV and is self-supporting, designed with reinforced plastic elements, rotatable baseplates, and optional resin post insulators for independent support.
