Die ausführliche Beschreibung der Marke: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 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
