    • The disclosure relates to a tape with nonlinear field control properties containing ZnO microvaristor particles. The doped ZnO particles are produced by crushing a sintered ZnO block, by desagglomeration or crushing of calcinated granulated particles, or by crushing of a calcined or sintered tape (tape casting). Embodiments, among other things, relate to: hollow ZnO microvaristor particles produced by granulation technique, having reduced average density and having diameters in a range well below 90 μm; and compounding the Zno filler in binders that are used to impregnate tapes. Compared to nonlinear field control tapes with conventional embedded nonlinear filler particles, a stronger and more reliable nonlinear resistivity is achieved and the ZnO filler is simpler to produce and to compound in the binder. The resulting tapes are flexible, preferably self-adhesive and have a strong nonlinear electrical resistivity. The tapes are useful to protect high field-stress regions in electrical components.
    • 本公开涉及具有含有ZnO微电阻颗粒的非线性场控制性质的带。 掺杂的ZnO颗粒是通过粉碎烧结的ZnO块,通过烧结或粉碎煅烧的造粒颗粒,或通过粉碎煅烧或烧结带(带铸)来制备的。 实施例尤其涉及:通过造粒技术制造的中空ZnO微电阻颗粒,具有降低的平均密度并具有在远低于90μm的范围内的直径; 并将Zno填料与用于浸渍带的粘合剂混合。 与具有常规嵌入式非线性填料颗粒的非线性场控制带相比,实现了更强和更可靠的非线性电阻率,并且ZnO填料更容易在粘合剂中生产和复合。 所得到的带是柔性的,优选是自粘性的并且具有很强的非线性电阻率。 磁带可用于保护电气部件中的高场应力区域。
