24 kV Two-Core Current Transformer (for Polluted Regions)
EWF-20DK
2-core current transformer for a 20~24kV power system. Used in conjunction with measuring or monitoring instruments, and with protective relays. Epoxy cast. Designed to have greater creepage, it is appropriate for polluted regions.
About the Product
This two-core current transformer is designed for a 20~24 kV power system and is intended to be used in conjunction with measuring or monitoring instruments, and with protective relays. Insulated with Araldite® epoxy, this indoor-use current transformer is designed to have greater creepage, allowing the current transformer to be provided to regions with harsh environmental factors such as high humidity, salty air, dust, etc.
Product Features
- Cast in Araldite® epoxy resin
- For indoor application in polluted regions
- Standards: IEC or IEEE
- System Voltage: ≦ 24kV
- Frequency: 50 or 60 Hz
- AC/BIL: 50/125 kV

Overvoltage Protector for Current-Transformer Protection
CCTP-03
When a power system is in operation, it is imperative that the secondary of the current transformer(s) should not have an open circuit. When an open circuit occurs, an extremely high transient voltage will be induced, which can in turn damage the current transformers and the instruments at the secondary, or even posing a threat to personal safety. This CT secondary overvoltage protector offers protection from such accidental damage caused by secondary transient voltage.
