UA-162404855-1
The HD series porcelain housing high voltage surge arresters provide excellent protection against over-voltage pulses. Although the porcelain housing has lost its popularity in the old and electricity distribution systems, we are able to produce in a way that can meet the needs of our customers.
Our main product groups:
3 – 51 kV SL & SM (Class 2 & Class 3, 10 kA) Porcelain Housing Surge Arresters
51 – 420 kV SL & SM (Class 2 & Class 3, 10 kA) Porcelain Housing Surge Arresters
You can find technical information about our standard production in our catalog.
