La description détaillée de marque:Consists of îïîðíî-èçîëÿöèîííîé design, screen system and øèíîäåð of æàòåëÿ. The Îïîðíî-èçîëÿöèîííàÿ design represents two ÿðóñí
óþ the space truss , consisting of subtly ñòðåæíåâûõ insulators,
connected among themselves by the horizontal stiffening ring.
the insulators fixing in chocks of stiffening rings is carried out casing
SIF. The screen bearing arrangement is established by the two single toroidal
screens from aluminium pipe and screen, made in the form of two with
îñíûõ toroids from small-diameter rod.
on top boom of support the plate is established, at which depending on
from òèïîèñïîëíåíèÿ can be errected bus clamps, HF
the minelayers, as well as fixed contacts of suspended isolating switch and
earthing rod.
the bus clamps design allows to joining of two leads of îøèíî
ICI by the diameter 25, 30 and 45 MM, as well as one lead by the diameter 45 MM.
