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

This paper describes and analyses 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 link in the world. The multiconductor cell analysis (MCA) of this land-submarine double-circuit single-core cables has been compared with an Electro Magnetic Transient Program (EMTP-RV) 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
