Portable medium-voltage mining trailing cable
A yellow polyurethane-jacketed portable trailing cable with three power, two ground and one ground-check conductor. The three voltage grades are kept in one family page with their individual insulation thickness and dimensional data.
Where it is used
Portable power to shovels, draglines, drills, dredges and other heavy mine equipment using compatible cable reels and ground-check circuits.
