I see. Does it protect the camera from excessive sync voltage? In case the excessive fries the camera

no, it won't, the best way to protect your camera is use wireless trigger.

however, most modern studio flash units are having low trigger voltage, very safe for electronic cameras.
Unlike those huge and bulky studio flash units made 20~30 years ago have high trigger voltage, will even give photographers some nasty short if not be careful.
