Explanation/Annotation:For grounding cut off from power sources of conductor in circuits
alternate current
Detailed model description:On construction _ hewn type.
the earthing rod pole consists of ground, fixed contact and ïîäâèæ
Noy earthing knives.
the fixed contact consists of copper contact, which is fastened
to aluminium contact, varnished by the copper. The transfer of rotational
a drive from drive on earthing rod shaft is embraced by way of ðû÷à
years, fixed on the line and earthing rod, joined by the draught out of the chimney
and support pole, excluding the appearing of circular currents in the system
draught.
the gyration transfer from earthing rod shaft to shaft further the pole
and earthing rod is carried out by the draught out of the chimney and insulation liner, claim
ëþ÷àþùåé appearing of circulating currents in basic shaft system, binding z
àçåìëèòåëè of various phases.
when mounting the earthing rods are connected in three the pole apparata, PAN
