detector of high voltage overhead electric lines - DECTRO 500

Certificate of conformity

Our solution, system "DECTRO"

System "DECTRO" is an overhead electric lines detector.

It is intented for any kind of vehicle such a metallic part is liable to touch contact accidentally with a high voltage electric line.

When the boom comes near the line, device start a visual and audible alarm and block the boom movement.

This one could be unbolted by user, after the line was located (DANGER) and with user responsibility.

Sensitivity of device was adapted for a 20000 volts overhead electric lines detection, in indicate the high voltage line presence in the environnment of vehicle.

Mean of prevention

Used like a mean of warning, detector alert user about high voltage electric line proximity, but doesn't shield user to safety orders application.
(décret 2008-244 du 7 Mars 2008 - obligations du code du travail - article R4534-108).
