PROJECT FOR THE EXECUTION OF THE 220 kV D/C S.E.T. OVERHEAD LINE BAZA 220/400 kV – S.E.T. 30/220 kV LIMIT IN BAZA AND CANILES IN GRANADA

Location: Baza and Caniles (Granada)

Main characteristics: 20.7 Km – 220 KV – Double Circuit

Year: 2019

The project consisted of the design of the execution of a 220 kV double circuit high voltage overhead line between the 220 kV LIMITE substation and the 220/400 kV BAZA RENEWABLE substation, with a transport capacity of 600 MVA.

The overhead interconnection is 20.7 km long with double circuit and one conductor per phase. The support structure is in lattice towers. The phase conductor is 485-AL1/63-ST1A LA-545 CARDINAL, and the guard cable is OPGW of a minimum of 48 fibers with a short circuit current of more than 17kA/0.3 seconds.

It is a complex orography and the line has to cross a great number of singular points (riverbeds, roads, other electric lines, etc).

Software used for the development of the project: PLS-CADC, Imedexa and others.
