The JDZX18-10R Voltage Transformer features epoxy resin casting and a fully enclosed construction, designed for indoor switch cabinet installation. It is used to measure current, electric energy, and provide protective relaying in single-phase or three-phase AC circuits. Operating at frequencies of 50Hz or 60Hz, it supports equipment with rated voltages of 17.5kV or 24kV, making it suitable for medium-voltage systems.
The transformer employs an advanced cold-rolled silicon steel sheet iron core, enhancing magnetic performance and reducing losses. The high-voltage primary winding output is arranged on the top of the product, while the secondary winding output is accessible from the transverse side, ensuring convenient wiring and installation.
