Descrição porminorizada da marca: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-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 of over-extensions
- high energy intensity
- enhanced resistance to pollution effects
- explosion safety and seismic resistance
