The JSZY18-24RJ Voltage Transformer features a fully enclosed epoxy resin casting insulation structure, where the primary winding, secondary winding, and annular core are completely embedded in resin. This construction ensures excellent resistance to dirt and moisture. The transformer is also equipped with an elbow-type plug that enhances environmental sealing and facilitates easier installation in compact switchgear systems.
This product is designed for indoor use in isolated neutral electrical systems, making it ideal for measuring current, electric energy, and protective relaying. Operating at a frequency of 50Hz or 60Hz, it supports equipment with a maximum voltage of 24kV, ensuring accurate and stable performance in medium-voltage applications.
