Detectors consist of working insulating part and handle.
The handle and insulating part are manufactured from section electrically insulating fiberglass plastic and case of working part from the material with high dielectric characteristics.
Detectors “Ekivolta 35-110K” and “Ekivolta 35-220K” ensure combined (visual and acoustical) indication of voltage presence. Visual pulsing light indication is the main one and acoustical signal is additional indication. Detectors “Ekivolta 35-110” and “Ekivolta 35-110K” ensure optical indication of voltage presence.
Detectors have some new technical decisions, which allow using ultra-bright light-emitting diodes and source of sound source with necessary power without built-in power source. Effective shade ensures reliable light signal recognition under bright illuminant conditions. Detectors don’t demand working part’s grounding.
The set of supply can be provided with device UPU for determining serviceability of high voltage detectors.
