STAGE 01 / 04
DrawingCopper Conductor
An 8 mm oxygen-free copper rod is drawn through 13 dies down to 0.21 mm filaments. Conductivity ≥ IACS 100%, with online tension compensation and eddy-current flaw detection.
INSIDE THE FACTORY
Step insidewhere copper meets the city.
53,605 m² of continuous production, six catenary cross-linking lines, a 47 m electric overhead crane — this is where every meter of 1 kV–10 kV cable is forged from raw oxygen-free copper into a pulse a city can trust.
Workshop note
In 53,605 m², the rhythm is steady.
The main hall runs 320 m end to end. The overhead crane glides past in 47 m beats. Copper rod is drawn to 0.21 mm filaments, stranded, cross-linked, screened, and finally laid down — heavy and quiet — onto wooden drums. Every step has a station, a tempo, and a traceable batch number.

FOUR STAGESFrom
From
a coil of copper to a grid-ready cable.
Nine QC gates and seventeen performance tests are compressed into four uninterrupted stages — each with a traceable process fingerprint.
STAGE 02 / 04
StrandingCritical Process
Filaments are bunched and laid up on a 60-disc frame strander, with pitch tightly controlled per GB/T 3956. The stranding station carries a dual-sign critical-process card.
STAGE 03 / 04
XLPE LiningInsulation & Sheath
Six catenary cross-linking lines run continuous vulcanization with triple-layer co-extrusion. Wall thickness is laser-gauged twice per meter, online.
STAGE 04 / 04
Test & StoreFinal QC
50 Hz withstand, partial discharge, full-length insulation and length metrology — once cleared, the cable is wound onto D2400 drums and barcode-tracked into the warehouse.
Light and steel across 53,605 m².
No slogans in the engineer’s viewfinder — just rhythm, on an ordinary day inside the main hall.
