Explicação, anotação:For protection against atmospheric overvoltage of electric equipment insulation
alternate current by the frequency 50 - 60 Hz
Descrição porminorizada da marca:For networks with any system of neutral grounding (15,
20, 35 kW) are being manufactured and for networks with effectively earthed neutral (33, 66, 110,
132, 150, 220 kW).
consist of one or several standard cells, each of êîòî
paradise includes the bloc of multiple spark gap and working ðåçèñòî
RU. The multiple spark gap is in series with ðàáî÷è
mi by resistors, is closed by the hermetic armoured case and has been squeezed ïðóæèíî é. The spark gap column is closed by the lid, protecting the top end of elemenes
that from atmospheric precipitations. The phase lead of high-voltage line of ïîäêë
