Explanation/Annotation:To protect electric equipment of transformer station and ac networks hour
òîòîé 50 cycles from atmospheric and short-term switching surge voltages
Detailed model description:The active part of clippers consists of in series with
zno resistors with high linear voltage-current õàðàêòåðèñ
teak.
the internal cavity of tyre with resistors shall be filled in heat-conductive
composition. The protective effect can be explained by the fact that in case of appearing is dangerous
ãî for over-extension insulation elapsing through impulse limiter
the humanitarian aid current because of high non-linearity of resistors shall not create dangerous
for insulation 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
