Does the A330's engine (the GE CF6) use only pneumatic power from the APU for reverse thrust? Please explain detailed. Sorry for my English.

Thrust reversers on high-bypass engines are airframe parts
The thrust reversers on a high-bypass turbofan such as the CF6 are treated as part of the nacelle, which is made by the airframer, as opposed to being part of the engine. This is unlike target-type thrust reversers, which are treated as engine parts by and large.
Airbus uses hydraulic reversers by and large
The reversers on current Airbii (including the A330 that you ask about) are hydraulic. This is in contrast to the B747 and the A300/310 which also use the CF6 engine and use pneumatic reversers (driven from high stage engine bleed air directly, not the general bleed ducts).

$\begingroup$ Why the two i's on Airbii? It would just be "Airbi" $\endgroup$– TomMcWApr 17, 2017 at 18:36
