Why are different naming standards compatible for use in the international market?

Compatibility is governed by International Electrotechnical Commission (IEC) standards, specifically IEC 60502-2. While the alphanumeric codes (like YJV vs. N2XSY) differ, both cables are engineered to meet identical electrical performance benchmarks, such as impulse voltage levels, partial discharge limits, and dielectric loss factors. As long as the cable’s rated voltage (U0/U), conductor cross-section (mm²), and insulation thickness align with project specifications, the cable is functionally interchangeable in global power grids.
