12 + 18 + 24 rigid frame strander copper aluminum steel core aluminum strand
Application:
Primarily used for the production of large - length bare aluminum, bare copper wire, and steel core aluminum strand. It is also applied to the stranding of circular conductors, sector - shaped conductors (both straight and pre - spiraling), and other electric cable cores.
Ideal for producing a variety of stranded wires with or without back - twist, and is involved in the production of power cables, overhead conductors, control cables, etc.

Suitable Cables
- Power cables: Round compacted Extra High Voltage and High Voltage Cables (HVDC, HVAC), as well as prespiralled sector cores for Milliken.
- Overhead conductors: Such as AAC, ACSR, AAAC, ACCC, ACSS
- Others: Steel wire armouring, copper wire screening, and flexible Class 5 cables, control cables.
Features:
- Simplified technology: As a variant of cage - type stranding machines, the rigid frame type doesn't have a separate pay - off device. The workpiece on the coils is installed directly into the stranding stands, which simplifies the technology.
- High - speed operation: In the torsion part, the pay - off coils with wire are arranged in 3 rows close to the rotation axis, allowing an increase in the line speed to 13.6 to 55.7 meters per minute
- High mechanical performance: Adopts a heavy - duty frame - type stranding cage, with the cage supported on self - aligning roller bearings at both ends. The totally enclosed gear and centralized lubricating system for bearings and drive to cages improve smooth operation and reduce noise.
- Quality assurance: Equipped with a constant - tension pay - off device for each bobbin to ensure product quality.
- Overall excellent performance: Features high mechanical strength, high reliability, high production efficiency, low energy consumption, a compact structure, and easy operation.
- Flexible speed control: The use of a frequency - converter motor drive enables stepless speed regulation, smooth start, no impact when replacing spools, and no damage to the machine.
- Long lifespan: Manufactured using materials from domestic and abroad famous factories, ensuring a long usage life.
