Medium-Voltage Current Transformers (10~25 kV)
Widely used internationally in revenue and switchboard applications by engineering, construction, and power companies, CIC Current Transformers are the result of over 40 years of manufacturing expertise, combined with technology transferred from Messwandler-Bau (MWB) of Germany.
The primary insulation material for CIC's current transformers is the Araldite® epoxy resin, known for its reliability. The outdoor models make use of cycloaliphatic epoxy resin, similarly to ensure high-quality insulation.
CIC's current transformers, including OEM/ODM products, are type-tested and routine-tested by CIC-owned, TAF-accredited Advanced Electricity Laboratory (TAF, or Taiwan Accreditation Foundation, is a member of ILAC and a signatory to the ILAC MRA).
Cut-core, medium-voltage, indoor-use, coil molded current transformer intended for a 15kV power system and suited for measuring or monitoring instruments. Insulated with Araldite® epoxy resin.
2-core current transformers designed for 12kV (max.) power systems for use with measuring (or monitoring) instruments and protective relays, these products are cast in Araldite® epoxy and meet the requirements of all major electrical standards.
Single-core and 2-core indoor window-type current transformers for power systems ≦ 15kV. Primary current: 500~3000A (single-ratio or multi-ratio). Araldite® epoxy resin. Used with measuring or monitoring instruments, or for protection.
EWF-20DA, EWF-20DB, EWF-20DD, EWF-20DE, EWF-20DS
For use in conjunction with energy meters or protective relays. Available in single-core, 2-core, and 3-core models. Insulated with Araldite® epoxy resin. Custom-made to meet various requirements.
2-core epoxy-cast current transformer for a ≦24kV power system. For use with measuring or monitoring instruments, and protective relays. “U-shaped top” design for safety and for a shorter distance between two current transformers installed side-by-side, thus reducing the required width of the switchgear panel.
For power companies. To be mounted inside the SF6 gas-insulated MOF panel of a 25.5 kV (max) power system. With 2 primary coils, this current transformer offers 2 current ratios while maintaining the required accuracy and burden rating at each current ratio. Insulated with Araldite® epoxy resin.
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.
Current transformers for installation in a switchgear panel of a 25kV (max.) power system and to be used with measuring or monitoring instruments, or protective relays. These are economic models suited to locations of high humidity or moderate pollution. The insulation material for the core and the secondary coil is Araldite® epoxy resin.
Multi-ratio bushing current transformers (bushing CTs, or BCTs) designed for 24kV draw-out circuit breakers and to be used with measuring (or monitoring) instruments or protective relays. IEEE 0.3 B-0.9. Cast in Araldite® epoxy.
Current Transformers / Extended Range Current Transformers (ERCTs) for Billing, 10~30kV Outdoor Type
Used for power monitoring or as part of a MOF (Metering Outfit) for a 12~36kV power system, these outdoor CTs for billing are insulated with Araldite® UV-resistant cycloaliphatic epoxy. Accuracy 0.15S~0.3; burden B-0.5. Available as Extended Range Current Transformers (ERCTs) if requested.
