1250mm Skip Stranding Machine for Up to 7-Core Cabling with or Without Back-Twist

Description and Application

As the first-of-its-kind skip stranding machine integrating full back-twist functionality, this equipment redefines efficiency in wire and cable processing. Unlike conventional cradle-type cabling machines, our skip strander delivers 4 times the productivity (i.e. More than 40 m/min linear speed), making it a core asset for high-volume production. It excels in skip stranding operations, handling soft-structure cables (control cables, Aluminum Conductor Steel Reinforced (ACSR) overhead cables, power cables) and bare copper, aluminum, aluminum alloy wires—supporting up to 7 cores.

The bow type laying up machine-inspired core mechanism, paired with back-twist, ensures uniform stranding, a key advantage over basic machines.

Features

1. User-friendly human-machine interface for effortless operation and comprehensive monitoring, letting new operators master this equipment quickly.

2. Adopts PLC for automatic pitch adjustment, maintaining precision in skip stranding and reducing manual errors.

3. Supports up to 100% back-twist mode, a standout feature that makes it more versatile than standard bow stranding machine variants.

4. Offers independent or ground shaft drive, a flexible design that aligns with diverse production needs—whether used as a standalone skip machine or paired with other equipment.

5. Uses AC induction servo motors for reliable, energy-efficient operation, ensuring long-term stable performance and lowering operational costs.

7. Capstan/Haul-off/Caterpillar, ensuring smooth cable traction.

8. Take-up with traversing, enabling orderly winding of finished cables.

9. Control system, coordinating all components for seamless operation.

10. Transmission system, ensuring stable power transfer for high-speed performance.

11. Wearing parts (critical for longevity, e.g., tension wheels, wire guides—spares included in initial delivery).

Q&A

Q1: Why do I not see other brands producing this kind of machine?

Ans: As of now, we’re the only Chinese company integrating back-twist into this specific skip stranding machine form factor. This design makes our equipment outperform similar-looking machines and traditional cradle-type stranding machines. The bow type laying up machine-based structure, combined with skip stranding efficiency, gives it a unique edge—one other brands haven’t replicated. This advantage ensures higher productivity and better stranding quality.

Q2: How to determine the right model of skip stranding machine for my production needs?

Ans: Choose based on your wire parameters, as each model is optimized for specific skip stranding scenarios:

1. 1250 model (with back-twist): Each core 10mm² - 240mm², up to 5 strands—ideal for medium-cross-section operations.

2. 1600 model (with back-twist): Each core 30mm² - 300mm², up to 5 strands—for larger-cross-section cables than the 1250 model.

3. 1250 model (without back-twist): Each core 7mm² - 28mm², up to 7 strands—cost-effective for basic needs.

4. 1600 model (without back-twist): Each core 9mm² - 50mm², up to 7 strands—high-capacity for multi-core processing.

If transitioning from a traditional machine, our team provides comparative analysis to ensure the model matches your upgrade goals.

Q3: What is the maximum stranding speed of the skip stranding machine?

Ans: For the two models with back-twist (1250, 1600), maximum rotation speed is ~100 rpm—translating to 40 - 60m/min linear speed with non-woven wrapping. This is a huge leap from traditional cradle-type machines (10 - 20m/min) and even high-performance bow stranding machine variants.

Q4: What after-sales support do you provide for the skip stranding machine?

Ans: We offer comprehensive support:

• Warranty: 12-month free warranty for the whole machine (excluding wear parts—spares included initially to minimize downtime).

• Technical support: 24/7 online consultation (email, phone, video) to fix common issues (uneven skip stranding, abnormal noise).

• Spare parts: Stock core parts (motors, control panels) for swift delivery, keeping operations on track.

• On-site service: Engineers handle major faults (e.g., transmission issues) on-site—service fees waived during warranty, only travel fees post-warranty. We also train your team for routine upkeep.
