Voltage Monitoring Insulators & Voltage Indicators

Voltage Indicators
Voltage Indicators

When our voltage monitoring insulator is combined with a specially designed light indicator, they form a voltage indicator set, which helps ensure the safety of power system operation. 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, our 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.
