probabaly be better off asking people in the guitar building and customising forum rather than here..........but im just gonna say that it seems like the standard sized fretwire (whatever that may be?)

It'd be a better idea to post a picture of the guitar neck from the side. with perhaps some kind of size reference next to it.

Those frets look quite tall and on most super-strat styled guitars you'd get a 6105 styled wire.

Just out of interest why do you want to know what type of wire is used?

If you really want a definitive answer then measure the height and width of the fret with a feeler gauge/caliper/whatever (needs to be accurate) and compare it to:
