Current Transformers 3.6-7.2 kV Series are primarily used for measurement, monitoring, or protection in motor control panels and other equipment. Models include single/double core epoxy resin CTs, coil molded CTs, terminal type, window type, and more. The main insulation material is Huntsman (formerly Ciba-Geigy of Switzerland) Araldite® epoxy resin. Current transformers can be manufactured according to IEC, IEEE, or other standards. Outdoor current transformers are also available per customer requirements.

Type tests and routine tests for CIC’s medium-voltage current transformers are all conducted by CIC's Advanced Electricity Lab, accredited by ILAC member TAF, ensuring quality. With decades of experience, CIC manufactures current transformers in a wide variety of specifications to meet diverse customer needs, also offering customization and ODM/OEM services. Thanks to high accuracy and reliable quality, CIC's products are widely used for metering and distribution by utilities, factories, major projects and builders globally.
