Drum Twister for High-Efficiency Power Cable Stranding

In modern power cable manufacturing, the Drum Twister is a key piece of equipment for stranding large-length and large-cross-section cables, including Milliken conductors. Compared with conventional stranding machines, drum twisters offer much higher production efficiency, with operating speeds generally exceeding 30 m/min. The large take-up drum, which can reach up to 4000 mm in diameter, allows longer continuous production and significantly expands the application range.

The Drum Twister supports both back-twist and non-back-twist processes. Pay-off bobbins can rotate synchronously with the take-up frame or remain stationary, while the take-up drum completes twisting and winding at the same time. This makes it suitable not only for conductor stranding, but also for steel wire or steel tape armoring, as well as copper wire or copper tape shielding. Multiple cable structures such as 3-core, 4-core, 5-core, “4+1”, and “3+2” can be produced on the same platform.

With sub-motor drive technology, high-precision components, and PLC control with a touch screen interface, the equipment ensures stable high-speed operation and easy parameter adjustment. Optional wrapping, armoring, and filling devices further enhance process flexibility, making the drum twister a reliable solution for high-capacity power cable production.
