High Precision 12kV–40.5kV Capacitive Voltage Divider Ceramic Core with Ultra-Low Partial Discharge and Low Dielectric Loss

Our capacitive voltage divider (CVD) ceramic cores are engineered as the key dielectric element for medium-voltage voltage measurement and monitoring systems. Manufactured with high-purity ceramic dielectric materials, these cores deliver stable capacitance values and ultra-low partial discharge, ensuring accurate voltage division across 12kV to 40.5kV distribution networks.

Designed for integration into voltage transformers, metering cabinets and smart grid monitoring devices, our CVD cores provide long-term reliability with minimal drift, making them ideal for utility-grade and industrial MV installations.
