Product introduction：
Field-suppressing resistor is a product developed by Xi'an Shendian on the basis of multi-year experience in firing technology of zinc oxide resistor to overcome the disadvantage of low energy absorption of common zinc oxide varistor. The resistor is mainly used in excitation circuit of a variety of large- and medium-sized synchronous generators, to provide rapid field-suppressing protection and transient over-voltage absorption for the generators.

It is featured by high unit volume capacity, fast response (NS level), high stability, and excellent voltage-sensitive characteristics.
