NYM-J NYM-O Cable

Details

Insulated and sheathed in PVC Copper Cable

NYM-O and NYM-J Cables have a voltage rating of 300/500V are supplied in single cores from 1.5mm2 through to 35mm2, and multi cores to 12 cores as detailed in the technical datasheets. Insulated and sheathed in PVC, the insulation dictates a maximum conductor operating temperature of +70oC, the NYM cable can be laid on cable tray, in ducting, or in walls, in line with relevant national building regulations.
