About system DECTRO

Hight voltage overhead electric lines detector - DECTRO 500


System "DECTRO" is a over line overhead electric lines device. 


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


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

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


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


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