Surge arresters OPNN-P are designed to protect the neutral in 110 kV electrical networks from switching and lightning overvoltages. The model with a discharge capacity of 1.4 C is manufactured according to TU 27.12.10-058-21639232-2022 and complies with GOST R 52725-2021 requirements.

Technical specifications:

• Rated discharge current: 10 kA
• Active power loss: at least 3.2 kJ
• Explosion safety current:
  • duration of at least 1 second: at least 0.6 kA
  • duration of at least 0.2 seconds: at least 65 kA
• Impulse current 4/10 µs: 100 kA
• External insulation design: for areas with pollution degree III
• Climatic version and placement category according to GOST 15150: UHL1

These arresters provide reliable equipment protection, preventing damage caused by overvoltages, and contribute to the overall reliability of electrical networks.
