. To produce copper or aluminum strands and ACSR of large cross section at long length without back twist.

. Adopting a centralized load or unload system with a pneumatic clamp to realize high efficiency.

. Adopting a constant tension pay-off with air pressure damp for each bobbin to ensure the product quality.

. With a fast checker without contact on every bobbin, it is easy for wiring.

. Double motorized haul-off, a wide range of stranding pitch, wires distributed automatically.

. Using digital DC drive, coordinated by programmable controller.
