Frequently Asked Questions
Q
What is the tension control range of this pay-off stand, and can it be adjusted for different wire sizes?
The tension control range is 50 N to 5000 N, adjustable in 1 N increments. This makes it compatible with both small and large cross-section wires, including round enameled wire (0.5 mm–50 mm diameter) and flat wire (5 mm×10 mm to 20 mm×50 mm cross-section).
Q
How does the closed-loop tension control system work?
The system uses a tension sensor to monitor real-time cable tension and automatically adjusts the braking force to maintain the set tension value within ±1% accuracy. This closed-loop feedback ensures stable and consistent tension throughout the entire wire pay-off process, preventing wire deformation or breakage.
Q
What types of transformers is this system compatible with?
This pay-off stand is compatible with a wide range of transformer types, including power transformers (10kV–1000kV), dry-type epoxy-cast transformers, rectifier transformers, and traction transformers. It supports both pancake and layer winding processes.
Q
Can this system support multi-conductor parallel winding?
Yes. The system supports simultaneous winding of 2 to 8 conductors with balanced tension control across all conductors. It also adapts to transposed conductor winding, preventing loose strands and misalignment, which is especially important for large, low-loss transformers.
Q
Is this pay-off stand suitable for outdoor or harsh construction environments?
Yes. The stand is constructed from high-strength, corrosion-resistant materials designed to withstand heavy cable loads and challenging outdoor conditions. It also features an anti-slip base for added stability, making it well-suited for complex construction sites and long-term use.
Q
Can this system be integrated with other production line equipment?
Absolutely. The pay-off stand is designed for automated production linkage and can be seamlessly integrated with winding machines, cutting machines, and insulation paper wrapping machines. It supports an end-to-end process of pay-off, winding, insulation wrapping, and cutting, while also logging tension data and issuing abnormality warnings for quality assurance.
