110kV SF6 Electromagnetic Voltage Transformer and Lightning Arrester

The 110kV SF6 electromagnetic voltage transformer has dual functions of voltage transformation and isolation, and has the function of proportionally converting high voltage into standard low voltage for metering, instrument devices, and relay protection. The product adopts capacitive technology to effectively prevent ferromagnetic resonance. The 110kV lightning arrester adopts a high gradient oxide resistor and segmented fixing process, which has the characteristics of good nonlinearity, excellent protection level, and uniform potential distribution. The product is applied in key projects such as Angola lomau and National Grid Nanjing South Station.
