Dry Type Voltage Transformers
Outdoor dry type current transformers are cast in high quality cycloaliphatic epoxy resin with high glass transition temperature. Dry type current transformers have excellent ultraviolet resistance and ingress protection for secondary terminal box. Voltage transformers can be designed in single pole or double pole constructions.
