Production Processes Of UL cable
JOCA produces UL wires using a fully automated workflow. The cycle synchronizes copper drawing and stranding with precise PVC or XLPE extrusion. Instead of waiting for post-production checks, we employ continuous inline monitoring—using laser diameter gauges and spark testers to catch defects instantly. For multi-core variants, the line handles cabling, shielding, and jacketing to exact specifications. Before shipping, every batch faces final electrical and mechanical inspections to verify full compliance with UL standards.
Packing For Shipment
To meet various transportation needs, there are many methods of packaging that can be used.
