About system DECTRO

High voltage overhead electric lines detector - DECTRO 500


System "DECTRO" is an overhead electric lines device. 


It is intented to any kind of vehicle  with a metallic part which may accidently touch a high voltage electric line.


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

It will can be unbolted by user, after to have located line (DANGER) and under his responsibility.


The device sensitivity has been adapted for an overhead electric lines 20000 volts detection, to indicate line presence in vehicle environment.


Used like a mean for prevention, the detector prevent user of high voltage overhead electric line proximity, but doesn't shield him from applying the safety rules.
