China Low-Voltage Tension Pay-Off Stand for Low-Voltage Transformer Coils Supplier, Suppliers

This Low-Voltage Tension Pay-Off Stand is a core auxiliary device for low-voltage electrical winding manufacturing. It enables precise tension control (5-500N adjustable) for small-cross-section wires (0.1-10mm diameter enameled/insulated wires), avoiding loose winding or insulation damage.

With stepless speed regulation (0.2-5m/min) and synchronization with winding machines, it ensures neat wire arrangement. Ideal for low-voltage transformer coils, motor windings, and household appliance coils, it boosts efficiency and guarantees winding quality, fully meeting low-voltage electrical production standards.

Advantages

1. Precise micro-tension control for small-section conductors

For fine-gauge conductors commonly used in low-voltage applications (0.1-10mm diameter enameled and insulated wires), the tension control range is precise, ranging from 5-500N (adjustable in 1N increments) with an accuracy of ±1%. This prevents excessive tension from thinning the conductor and damaging the insulation.

2. Flexible adaptability for multiple scenarios and strong compatibility

Compatible with a variety of conductor types (round enameled wire, flat insulated wire, and thin wire bundles). Supports over 50 pre-set process parameters, eliminating the need for repeated adjustments when switching between conductor types.

3. Good automation linkage reduces labor costs

Supports PLC linkage (e.g., RS485 communication) with winding machines, automatically synchronizing the payout speed (0.2-5m/min) with the winding rhythm. Some models feature wireless remote control for improved workshop safety.

4. Comprehensive safety measures reduce scrap rates

Built-in abnormal tension alarms, wire break detection, and wire jam protection. Guide wheels are made of wear-resistant polyurethane, keeping thin wires scratch-free and reducing the risk of scrap.

5. Compact and easy to deploy

Vertical design occupying ≤1.5 m², weighing approximately 300-800 kg. No dedicated heavy foundation required. Operating noise level ≤60 dB, ideal for precision production environments.

Application Areas

I. Low-Voltage Distribution Transformers

Controls 5-300N tension for 0.5-5mm wires to keep coils tight. Syncs with layer winding machines for even arrangement.

II. Low-Voltage Control Transformers

Uses 5-50N low tension to protect thin wires (0.1-1mm) from enamel damage. Maintains stable speed to reduce turn count errors.

III. Low-Voltage Isolation Transformers

Polyurethane guide wheels and ±1% tension accuracy protect thin insulation layers for medical or PV use.

IV. Dry-Type Low-Voltage Transformers (Epoxy-Cast)

Ensures wire spacing error ≤0.1mm to avoid casting bubbles. Guarantees coil consistency for mass production.
