The biggest manufacturer of metal oxide varistors blocks will produce which you would like in your metal oxide arrester.
The technical parameters are below, they are typical types, if you need other diameters or height, plesae send me email email@example.com, our metal oxide varistors R & D department will provide a satisfactory answer to you.
TGE’s metal oxide varistors have more smooth V-A curve characteristic and lower residual voltage under the same reference voltage.
Therefore, arresters which used TGE metal oxide varistors have below advantages:
--With the same reference voltage, hold more excellent protective characteristics;
--With the same protection level, arrester have higher reference voltage and continuous operating voltage. Therefore, arrester could withstand lower electric stress and for safe operation.
