Voltage Indicator for a Medium-Voltage Power System (24 kV)

CVDI-24 Voltage Indicator

Our CVDI-24 Voltage Indicator is designed for a system voltage of 24 kV.

About the Product

Voltage Indicators help ensure the safety of power system operation. Our CVDI Voltage Indicator comprises of a high-quality voltage monitoring insulator in conjunction with a light indicator. The voltage monitoring insulator detects system voltage, and the light indicator displays system voltage status.


  • Made with Swiss-imported epoxy resin and carefully selected, high-quality components, CVDI Series Voltage Monitoring Insulators are durable and resistant to pollutants and contaminants.
  • Voltage monitoring insulators can be purchased separately.

Conditions for Operation

  • The altitude of installation site should not exceed 1000m.
  • The temperature of surrounding environment should be between -25℃ and +80℃.
  • Regular maintenance is necessary if installed in a highly polluted or contaminating area.
