Anti-Tank AP rounds.
It severed both wings, but by sheer luck probably missed the fuel tank. Unless the AP connects to an explosive content, it will just cause non-explosive structural failure. If the hits shown above is all, I don't see a direct hit to the cockpit. No pilot death, so no explosion in this case too.
If it was a 30mm, the multiple hits near the cockpit would have damaged the pilot very badly due to HE, which probably would have killed him, thus, causing an explosion.
ps) it is tho, interesting the tail remains intact, despite the fact the screenshots show one hit to the rear fuselage section. Maybe the tail fell off too, but its not shown in the above series of pics?
