在模拟线棒上绕包一层防晕材料，测试其电阻在场强变化下的非线性特性，探讨防晕材料非线性特性的测试及计算方法，并对比了部分国内外防晕材料的非线性特性。结果表明：国外某公司的防晕高阻带A的非线性特性较好，防晕高阻带B的非线性特性较好，而自制高阻带C的非线性特性一般。
The simulation winding bars were winded a layer of anti-corona material, and their nonlinear characteristics under different elctric field intensity were tested. The test and calculation methods of non-linear characteristics were studied, and the nonlinear characteristics of domestic and foreign anti-corona materials were compared. The results show that the anti-corona material from a foreign company has good nonlinear characteristic, and the domestic anti-corona material needs to be improved.
