Different Bonding Types of Scilla–Villafranca (Sicily–Calabria) 43-km Double-Circuit AC 380-kV Submarine–Land Cables

This paper describes and analyzes the extra-high-voltage double-circuit cable line between Sicily and Calabria which is a reinforcement of the Italian southern transmission grid. This is one of the longest ac submarine links in the world. The multiconductor cell analysis of this land-submarine double-circuit single-core cables has been compared with an electromagnetic transient program model with a very good agreement. The different choices of bonding systems implemented in the real Italian installation are theoretically justified by means of the two-software comparison.
