APPLICATION AREA
The fixed protective shield of the OPJC type is designed for safeguarding of electric traction supply wires
against accidental touching of energized wires by passing personnel or other persons that may approach or
work nearby, e.g. at crossing of walkways with transportation roads, at loading and unloading stations at
underground mining operations where electric traction with the rated voltage of 250 V is deployed.
APPLICATION CONDITIONS
The OPJC fixed protective shield for trolley wires of electric traction networks is suitable for working areas of
underground operations without the hazard of methane explosion and the ones with the ‘a’ degree of methane
explosion hazard as well as with the ‘A’ class of coal dust explosion hazard.
TECHNICAL CHARACTERISTICS
The OPJC fixed protective shield for trolley wires is made up of the following components:
CONFORMITY WITH STANDARDS
The OPJC fixed protective shield for trolley wires of electric traction networks are manufactured in line with rules
of good engineering practice in the field of occupational safety as well as current state-of-art in technical
expertise with consideration to applicable technical standards and the 2014/35/UE Low-Voltage Directive.
