A stranding machine can look suitable on paper and still be the wrong choice for a particular production line. Wire material, single-wire diameter, number of wires, reel size, and target speed can all change the machine configuration.

The JGG Tubular Stranding Machine is designed for copper, aluminum, and steel wire stranding, including 7-, 12-, and 19-wire round or sector-shaped conductors. The available configurations give manufacturers room to handle different conductor specifications, but the machine still needs to be matched with the actual production job.

For HF Smarter, this is where the equipment discussion usually starts. Instead of choosing a machine from one headline specification, the production requirements are checked first and the machine configuration is then worked out around them.

The Wire Material Changes the Configuration

Copper, aluminum, and steel wire do not have the same production characteristics. Wire diameter and reel size also vary between different applications.

The JGG Tubular Stranding Machine is designed for all three materials. Depending on the selected reel configuration, the working diameter ranges are different.

For example, the Φ500 mm configuration lists:

• Aluminum wire: Φ1.5–4.0 mm
• Copper wire: Φ1.5–4.0 mm
• Steel wire: Φ0.75–3.0 mm

Other reel configurations cover different diameter ranges.

So if a factory is buying a tubular stranding machine, the first information to provide should be the actual wire material and diameter. A machine selected only by its maximum speed may not be the right fit for the wire that will be processed every day.

How Many Wires Need to Be Stranded?

The finished conductor is another important part of the specification.

The JGG machine is designed for 7-, 12-, and 19-wire round or sector-shaped copper and aluminum conductors. It can also be used for steel wire stranding.

A factory producing several conductor structures needs to look at the complete production range rather than one finished cable size.

For example, if the production plan includes both 7-wire and 19-wire conductors, the machine configuration should be discussed around both products before the purchase order is placed.

This is a simple point, but it can make a considerable difference to the usefulness of the equipment after installation.

Maximum Speed Is Not the Only Number to Compare

Machine brochures often put maximum rotation speed near the top of the specification sheet. It is useful, but it does not tell the whole story.

The JGG is available with different bow cradle and reel configurations. Depending on the setup, the maximum rotation speed ranges from 700 to 1,500 rpm.

The available reel sizes include Φ200 mm, Φ315 mm, Φ400 mm, and Φ500 mm.

A smaller reel configuration may provide a higher rotation speed, while a larger reel can accommodate a different wire range. The right choice therefore depends on what the factory wants to produce.

When comparing a wire tubular stranding machine, buyers should put the target production speed next to the actual wire diameter and reel requirement. That gives a much more useful comparison than looking at rpm alone.

Tension Control During Stranding

Once several individual wires enter the stranding process, keeping their tension under control becomes important.

The JGG uses band-type brakes for wire tension control. Germany hysteresis brakes are also available as an option. The HMI+PLC system supports wire tension control and automatic tension compensation.

The machine's main rotor, pulling capstan, and take-up unit are driven independently. Their operation can be synchronized through the control system.

For production teams, this arrangement helps keep the stranding and take-up processes coordinated when operating at different production speeds.

What Happens When the Production Job Changes?

A factory may not run the same conductor specification all day.

One order may call for a different wire diameter, another may require a different number of wires, and production speed may also change. This is why the control system is worth looking at before buying the equipment.

The JGG uses HMI+PLC control. Operators can set the stranding pitch, manage wire tension, use automatic tension compensation, and synchronize the machine with the take-up unit.

The purpose is fairly straightforward: make the machine easier to adjust when the production job changes.

Reel Size Should Match the Production Plan

Reel selection is easy to overlook during the early purchasing stage.

The JGG can be configured with Φ200 mm, Φ315 mm, Φ400 mm, and Φ500 mm reels. The choice affects the wire diameter range, machine speed, and overall production setup.

For an existing factory, the reel size already used in production is useful information to provide to the supplier. For a new production line, the planned conductor size and output should be discussed first.

This also gives the engineering team a better idea of how the machine will fit into the rest of the line.

Continuous Production Also Means Maintenance

High-speed equipment needs more than a suitable motor and control system. Bearings and other moving parts also need proper lubrication during operation.

The JGG uses a circulating pump lubrication system for its bearings. High-pressure injection provides both lubrication and cooling.

For a manufacturer planning long production runs, this is worth checking during the equipment evaluation. Maintenance arrangements can affect machine availability just as much as the production specifications.

Information to Prepare Before Requesting a Quote

If you are contacting a supplier for a tubular stranding machine, sending the actual production data will make the discussion much easier.

The basic information includes:

For an existing production line, photos or basic information about the upstream and downstream equipment can also help when discussing the configuration.

Service Matters When the Machine Goes Into Production

The purchasing decision does not end when the machine leaves the factory.

The JGG Tubular Stranding Machine is supported by 7-day, 24-hour technical service. The machine has a remote troubleshooting communication module, and engineers can provide remote assistance within 24 hours. Online support and on-site engineering service are available when needed.

Installation and commissioning can include mechanical and electrical engineering support, no-load testing, load testing, and acceptance testing.

For overseas cable manufacturers, having these services available can make the transition from delivery to actual production much easier.

FAQ

Start With Your Production Requirements

A tubular type stranding machine should be selected according to the wire and conductor specifications that will actually run through the machine. Material, diameter, number of wires, pitch, speed, and reel size all have a role in determining the suitable configuration.

HF Smarter has experience in wire and cable equipment and provides engineering support throughout the equipment project. For the JGG Tubular Stranding Machine, the configuration can be discussed around the customer's actual production data rather than a fixed standard setup.

If you are planning a new stranding line or replacing existing equipment, send us your wire specifications and production targets. HF Smarter can help you work out the JGG configuration that fits your production.
