Composite insulator Overall bar type design, compact structure, high quality, weight is 1/10 of the same grade porcelain and glass insulators, extremely convenient transportation, and installation. It is suitable for fouling areas, high mechanical tensile load, large span, and compact lines. The foul flash voltage is 30%-50% higher than that of porc...
Research shows that the heat generation of power line insulators consists of three parts.One is the heat generated by the polarization effect of the dielectric excited under the action of the working frequency voltage.Second, the internal penetrating leakage current heating.The third is the surface creepage leakage current heat generation.?W...
