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 to
òîðûõ includes the bloc of multiple spark gap and working ðåçèñ
torus. The multiple spark gap is in series with ðàáî
whose resistors, is closed by the hermetic armoured case and has been squeezed ïðóæè
Noy. The spark gap column is closed by the lid, protecting the top end ýëåì
åíòà from atmospheric precipitations. The phase lead of high-voltage line under
êëþ÷àåòñÿ to contact plate in the lid, and the grounding lead _
to bolt of steel base plate directly or through registrant
operation. To lid of upper element of spark gaps on nominal
voltage 110 kW and higher is fastened shading ring.
