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

Detailed model description:The active part of clippers consists of
Noy zno resistors with high linear voltage-current of õàðàê òåðèñòèêîé is series connected.
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
over-extensions
- high energy intensity
- enhanced resistance to effects
pollution
- explosion safety and seismic resistance
