ProductIEC 60228
Use / Applications
Soft copper bare conductors are ideal for the connection and development of grounding systems, thanks to their high electrical conductivity and strong resistance to aggressive environmental factors.
Construction: Bare conductor with concentric wiring according to IEC 60228 standard formed by soft copper wires.
Ampacities of bare copper conductors
Current carrying capacity in open air at 40°C ambient temperature and the conductor at 80°C. Source: RIC N°4 Table 4.3.
