Frequently Asked Questions
Q
What is the tension control range of this pay-off stand, and can it handle both thin and thick wires?
A
The tension control range is 50 N to 5000 N, adjustable in 1 N increments. This wide range makes it fully compatible with both small cross-section wires (as thin as 0.5 mm diameter) and large cross-section flat wires (up to 20 mm×50 mm), covering the majority of transformer winding applications.
Q
How does the closed-loop tension control system work to maintain accuracy?
A
The system uses a built-in tension sensor that continuously monitors the actual wire tension during pay-off. Any deviation from the set value is detected and corrected in real time, maintaining a tension accuracy of ±1% of the set value. This ensures stable, consistent wire feeding throughout the entire winding process.
Q
Is this pay-off stand compatible with automated winding production lines?
A
Yes. The stand is designed for seamless integration with winding machines, cutting machines, and insulation paper wrapping machines. Its wire feeding speed (0.5–10 m/min) can be synchronized with transformer coil winding machines, enabling a fully automated, integrated production workflow including pay-off, winding, insulation wrapping, and cutting.
Q
What types of wire and cable can this stand accommodate?
A
The stand supports round wire with diameters from 0.5 mm to 50 mm (including enameled copper wire and enameled aluminum wire), as well as flat wire with cross-sections from 5 mm×10 mm to 20 mm×50 mm (including paper-insulated flat wire and bare flat copper wire). It is suitable for both standard and specialty transformer coil winding.
Q
What safety features are included to prevent accidents during operation?
A
The pay-off stand is equipped with an anti-slip base that prevents tipping during operation. The flexible tension-adjustment components allow real-time fine-tuning based on actual construction conditions, reducing the risk of sudden tension changes. The system also records tension data and provides abnormality warnings to alert operators to any issues promptly.
Q
Can this stand be used for multi-conductor parallel winding applications?
A
Yes. The stand supports balanced tension control for the simultaneous winding of 2 to 8 conductors. It is also compatible with transposed conductor winding, effectively preventing loose strands and misalignment, making it ideal for low-loss winding requirements in large transformer manufacturing.
