The JG500/630 series can be used as a tubular strander for copper wire and a tubular strander for aluminum wire. The supported copper wire diameter ranges from 1.2 to 5.0 mm, while the aluminum wire diameter ranges from 1.5 to 5.0 mm. Both configurations feature a maximum twisting diameter of 21 mm, a cage speed of 500 r/min, a stranding pitch range of 40–448 mm, and a capstan speed of 15–138 m/min. These specifications help buyers evaluate machine suitability for their conductor production requirements.
