4.Maximum wind velocity :less than 35m/s.
5.The filthy area should be given clear indication.
PRODUCT FEATURE
YH10WZ-108C3850 Metal oxides surge arresters without gaps are designed to prevent probable damages in the case of typical surges in energy systems while it has no negative effect on energy systems in normal operation voltage. This special feature of gapless arresters originating from non-linear characteristics of metal-oxide varistors between voltage and current scales. The non-linear feature is much higher compared to SiC surge arresters.
