10kV Multi-Ratio Current Transformers (Single-Core & Two-Core Types)

Medium-Voltage Current Transformers (10~25 kV)


About the Product

Intended for 15 kV (max.) power systems, the EO-10SC Series current transformers for indoor application are available in single-core and two-core types. With a rated primary current of 500~3000A (single-ratio or multi-ratio), these current transformers are insulated with Araldite® epoxy resin and can be used with measuring or monitoring instruments, or for protective purposes. The window-type design facilitates installation and wiring with a busbar or a suitably insulated primary conductor, decreasing the occurrence rate of contact point failure. Characterized by excellent physical and electrical properties, the EO-10SC Series current transformers have consistently met with a high level of customer satisfaction.
