Oil filled cables are used, as back in the 1960's they were
the most cost effective method of implementing HV cables. It
wasnt until recent developments in XLPE cable that it became
a viable option instead of FFC. Fluid Filled cables are
mainly used as underground EHV ,extra high voltage,
typically 132kV in the uk.
the down side to these cables is that if they leak they can
cost a huge amount to repair. for a 30metre replacement of
FFC and 2 joints costs approx £100,000 GbP. also this type
of replacement could take up to 10 weeks to complete, with
excavations and leak detection.
to replace 15km of FFC with XLPE has been costed at
30million GBP.
FFC's are also often used in sub marine cables.
