Copper Wire Stranding Machine for Making Power Cable

Copper Wire Stranding Machine for Making Power Cable

1.Features
1) The rigid stranding machine is used for stranding Copper, Aluminum and Aluminium alloy wires and conductors with long length and large cross section.
2) Stranding compressed, compacted round or sector shaped ( straight or pre-spiraling ) as per customer requirements.
3) We also customise this cage type stranding machine in accordance with customers' requirements.

4) Rigid frame stranding is designed with 1+6+12+18+24+30+36 Bobbin Cage.
5) Bobbin: 500mm, 630mm, 710mm DIN 46397 Standard / Modified.
6) Heavy duty frame type rigid cage stranding machine, Cages supported on self aligning roller bearing on both ends. Totally enclosed gear, centralized lubricating system for bearing, drive to cages.

7) High efficiency and speed. Cage max speed 253 RPM. Max line speed 62.3 m / min.
8) Motorised / manual bobbin pintles with safety interlock. Wire-break detection installed for each bobbin.
9) Bobbin group loading using hydraulic floor type. Side trolley loaders is also optional.

10) Slanted design double wheel capstan suitable for heavy compacting loads. 1500mm-2500mm diameter. Traction force 10000kg.
11) Disk type Pneumatic brake for Cage.
12) PLC Equipped, optional.

2.Main Data
Precise boring: After completing all the welding and turning, the final step is precise boring. Boring is done on the special boring lathe. The holes for one set of clamping device, are bored at one time. This process ensures the concentricity, and effectively reduces the rate of wire-break.
Since improved the technology, more than 45000 sets of clamping devices have been used and no breakdown report. Customer's feedbacks are extremely positive.

During the process of turning, host cage of the frame stranding machine, can be completed at only one time of loading. So, the process greatly increases the concentricity.

The key gearboxes adopt the best gearboxes in China. The gearbox is almost no noise. Normally the gearbox will work for 5 years with no problem.

The production speed is extremely fast. For example, 240mm² bare wires, pitch 200mm, the speed is 3000m/h. So, in 10 hours, the stranding machine can produce 30000m wires. If we reduce the loading and unloading time, and host stop-time, for example 3 hours, 15000 meters to 20000 meters conductor can be produced. Production capacity is very very high.

The each host stranding cage is divided into four equal parts. The host disc and frame structures are integrally welded. The parts of the stranding cage are preliminarily turned, remaining machining allowance. The host stranding cages finally finish turning integrally. Equipped with pneumatic brake function, can performs the inch action, start and stop functions. The bobbins in the cages can be loaded and unloaded intensively, pneumatic clamped. Wire tension is pneumatic tension, which keeps constant wire tension. The whole chassis is integrally welded. Brake system is disc brake.

One electromagnetic wire-break stopping devices to each bobbin clamping device. One induction stopping device is on the mechanical meter counter. These devices will detect 99.9% wire-break.

Separate electronic control system. The hydraulic system controls the lifting and landing of the bracket. Slow positioning system makes sure the loading and unloading accurate angle. The loading and unloading are automatic positioning, which is very simple operation. The bobbins are loaded and unloaded integrally. When the bobbins are clamped, mechanical safety device will provide 700kg locking force to keep the bobbin clamped on the clamping device.
