The secondary coil of this series current transformer adopts PET polyester film with excellent electrical performance as the insulating material. The external coil has a waterproof layer, which can be waterproof and moisture-proof, and is suitable for air operation environments, while the built-in coil has no waterproof layer, which is suitable for low micro-water environments, such as SF6 or mixed gases. The coils can be used in a variety of power products such as GIS/HGIS combination electrical appliances, GCB can-type circuit breakers, open-type current transformers, transformers, etc., to provide accurate current signals for the secondary measurement, metering, protection, and transient protection equipment of the power system.
