Rigid stranding wire drawing machines are specialized equipment used in the wire and cable industry for stranding or twisting multiple wires together to form a single conductor. These machines are designed to handle large length bare aluminum wires, bare copper wires, and aluminum conductor steel reinforced (ACSR) cables. They can also produce round or sector-shaped conductors.

Here are some key features and specifications of rigid stranding wire drawing machines:

Features:

The machine is constructed with a rigid frame or cage-type structure, providing high mechanical strength and reliability.
The gearbox includes hardened-teeth gears, ensuring smooth operation and reducing noise.
The machines are equipped with a constant tension pay-off device for each bobbin, ensuring consistent wire quality.
They have a frequency converter motor drive, allowing for stepless speed regulation and smooth start-up.
Motorized or manual bobbin pintles with safety interlocks are included, and wire-break detection is installed for each bobbin.
The machines are designed for high production efficiency, low energy consumption, and easy operation.
Specifications:

The machines are available in various models with different capacities and capabilities, depending on the wire diameter, stranding diameter, rotating speed of the cage, and stranding pitch.
The single wire diameter can range from copper 1.5mm to 4.5mm and aluminum 1.8mm to 5mm.
The maximum stranding cross-sectional area can be up to 630mm for copper and 1000mm for aluminum.
The maximum speed of the cage varies depending on the number of bobbins, ranging from 48 to 156 RPM.
The stranding pitch can range from 38mm to 950mm.
The machines are equipped with various components such as pay-off stands, stranding cages, closing die stands, reducers, length counters, capstans, take-up units, and control systems.
These rigid stranding wire drawing machines are widely used in the wire and cable industry for the production of various conductors, including ACSR, bare copper or aluminum conductors, and insulated strands. They offer high production capacity, excellent wire quality, and versatility in stranding different wire combinations.
