Polymer Housed Lightning Arrester (YH Series)
Product Characteristics
For this series of surge arrester, the model of gapless metal oxide lightening arrester with composite bushing for AC power system is started with YH, which is used to limit overvoltage in system and protect power transmission and transformation products from overvoltage damage. The product is mainly composed of high-voltage terminal, metal oxide resistor, external insulator, low-voltage terminal and lower flange etc. With high temperature vulcanizing(HTV) silicone rubber, the external insulator is one-time injection molded. The low-voltage terminal of the lightening arrester is used to connect the on-line monitor or discharge counter.
