  • Outdoor-Type Current Transformers / Extended Range Current Transformers (ERCTs) for Revenue Metering (12~36 kV)
    Outdoor-Type Current Transformers / Extended Range Current Transformers (ERCTs) for Revenue Metering (12~36 kV)
    AWF-12, AWF-24, AWF-36

    These outdoor current transformers for revenue metering, intended for 12~36 kV power systems, are used as part of an MOF (Metering Outfit) or for current monitoring. Insulated with UV-resistant cycloaliphatic epoxy resin, these medium-voltage (MV) current transformers are ideal for outdoor use and can be available as Extended Range Current Transformers (ERCTs) when requested.


  • High-Voltage (HV) Outdoor Current Transformer, 52 kV & 72.5 kV
    High-Voltage (HV) Outdoor Current Transformer, 52 kV & 72.5 kV
    AWF-52, AWF-72

    These high-voltage current transformers (52 kV or 72.5 kV), designed for outdoor use, are available in single-core and two-core varieties. Featuring extended creepage distance and insulated with UV-resistant cycloaliphatic epoxy resin, these current transformers can withstand solar ultraviolet radiation and IEC-defined pollution level III (“Heavy”). They’re especially ideal for regions with salt fog, high temperature, and high humidity.
