A power cable factory is best described by its production chain, because every stage of the chain reappears later in the finished cable's test records. The XinYa facility in Guangdong's Pearl River Delta converts copper and aluminium rod into IEC 60502 power cable through four stages, each independently measurable. The conductor stage covers drawing, annealing and stranding to IEC 60228 — Class 2 for fixed power cores, Class 5 for flexible — with shaped-wire compaction on larger sections to raise fill factor and roundness. Conductor resistance is checked against the IEC 60228 tables before the wire leaves the stage. The insulation stage divides by crosslinking route: silane graft for low-voltage and building products, peroxide cure in a dry continuous-vulcanisation tube for XLPE medium-voltage cores, where triple extrusion lays conductor screen, insulation and insulation screen in a single pass. The cure line's temperature and pressure profile is the plant's most consequential process record, because voids created here return as partial-discharge sites, judged later against the 10 pC routine limit. The armouring and sheathing stage applies steel tape, steel wire or aluminium wire armour, then an extruded oversheath carrying printed type designation and metre markings — the traceability spine that lets a site inspector connect any metre back to its drum and its lot-level routine records. The verification stage is what buyers ask to see: production-length spark testing, drum-by-drum high-voltage withstand, partial-discharge measurement, hot-set ovens under IEC 60811, and combustion rigs feeding EN 50575 Declarations of Performance. A laboratory that runs these tests in-house issues reports an external facility can only reproduce. Guangdong completes the picture as logistics: rod, compounds and accessories sit within the same supply cluster, and export freight moves through nearby ports. A manufacturer reads best through its lines and its records — both of which are open to audit.
