Product Features
  • High voltage ceramic capacitor core rod rated at 12kVAC with 300pF nominal capacitance
  • Wide capacitance range: 270~330pF at test conditions
  • Excellent withstand voltage: 52kVAC/5min in insulating oil
  • Low partial discharge: ≤10pC at 13.2kVAC
  • High lightning impulse resistance: 75kV at 1.2/5μs
Application Areas

Designed for live display devices in 10kV-40.5kV power systems, this capacitor provides real-time indication of the operating status of:

  • High-voltage conductors
  • Circuit breakers (SF6 and vacuum types)
  • Lightning arresters
  • Instrument transformers

Ensures operator safety with typical parameters including capacitance ranges from 10pF-230pF (e.g., 90pF at 24kV), withstand voltage of 68kV (power frequency) and 125kV (lightning impulse).

Installation & Usage Instructions

PD not more than 5pC at 1.1 times rated voltage without special instructions. Comply with standard DL/T538-2006 (High Voltage Presence Indication Device).

Dimensions can be customized according to customer requirements.

Special attention required to prevent product damage, moisture exposure, and contamination.

Complies with standard JBT10305-2001 (Technical conditions for post insulator of organic material in the 3.6kV-40.5kV high voltage equipment).

For installations below 100 meters or in high altitude areas, please specify in order notes.
