Zinc oxide varistor and method for providing such varistor. |
摘要 |
<p>A high voltage varistor for DC operation is manufactured by applying a glass collar to the perimeter of a sintered zinc oxide disc and heat treated between about 750°C and 400°C for several cycles in air. After heat treating, an organic resin or ceramic coating is applied to the glass collar to further insulate the varistor for high voltage application.</p> |
