Resistor sheet for AC arrester
product description
Metal oxide resistors are semiconductor ceramic components made of
zinc oxide as the main raw material. Their resistance changes
nonlinearly with changes in applied voltage. Metal oxide resistors
are mainly used to assemble various types and levels of lightning
arresters. They are the core components of metal oxide arresters.
Their quality directly determines the performance of the arrester.
The metal oxide resistors produced by our company have the characteristics of large current capacity, high protection performance, good non-linear characteristics, beautiful appearance, and various specifications. The voltage gradient range is generally 200~230V/mm, and the diameter and height can be customized according to the customer's requirements. The demand can be determined flexibly. The maximum diameter of the resistor can be up to 138mm, and the maximum height can be up to 41mm.
