Zinc Oxide for Arrester Purpose

?In the electronics industry, Zinc oxide for arrester purpose is mainly used to manufacture the magnetic elements of electronic structure-Ferrite, moreover, TV radio, telecommunications installations and rheostat all adopts such magnetic materials.
?Compared with the traditional silicon carbide arrester, Zinc Oxide arrester has good protective characteristics, flow capacity, anti pollution ability, simple structure, high reliability, can provide the best protection for power transmission equipment, the power sector has been recognized.

Standard: JB/T9670-1999
