surge arrester YH10W-12S
YH10W-12S
Describe：ZnO lightning arrester is one kind most world advanced over-voltage protector at present due to its core components of resistance applying ZnO and other metal oxide to make of comparing with traditional carborundum arrester，it improves greatly V-A characteristics of resistance，increases the getting through ability of resistance，thereby it brings fundamental，change to features of arrester.
