High Voltage Component Free Sample
|The ZnO arrester is mainly to protect transformer, cable connector, and other electric equipment in the power distribution net from being damaged by lighting impluse voltage and over-voltage.
Vasitor, as core component of the ZnO arrester, has the advantages of excellent stable varistor properties, large nonlinear coefficient and ultrahigh breakdown voltage.
