How to Choose a Rigid Frame Strander for High-Quality Cable Production

For large-section copper and aluminum conductors, stranding quality affects cable performance and production efficiency. A Rigid Frame Strander with individual motor drives offers an alternative to traditional ground-shaft transmission, reducing mechanical complexity, operating noise, and maintenance demands.

Each cage and capstan has a separate motor, allowing stepless stranding-pitch adjustment to accommodate different conductor designs. Automatic bobbin loading and unloading, together with pneumatic tension control, can shorten changeover time and maintain more consistent wire tension as bobbins empty.

When evaluating a Rigid Frame Strander, compare conductor sizes, cage configuration, achievable pitch range, and loading automation. These practical factors help determine whether the machine fits your production requirements and long-term operating goals.
