Schiaramento/annotazione:To protect electric equipment of transformer station and ac networks hour
òîòîé 50 cycles from atmospheric and short-term commutation ïåðåíàïðÿ

Descrizione del marchio dettagliata:The active part of clippers consists of in series with ok
ñèäíî-öèíêîâûõ resistors with high linear voltage-current õàðàêòåðèñòè
SIF .
the internal cavity of tyre with resistors shall be filled in heat line
Noy composition.
the protective effect can be explained by the fact that in case of appearing of dangerous to iso
over-extension ëÿöèè elapsing through clipper the pulse current
because of high non-linearity of resistors shall not create dangerous to iso
ëÿöèè of voltage rise.
priority
- low protective level for all types of over-extensions
- high energy intensity
- enhanced resistance to effects
pollution
- explosion safety and seismic resistance
