Stretch When You Need It, Retract When You Don't — Uninterrupted Power for Equipment in Motion

On the floors of industrial machinery facilities, medical device environments, and power tool applications, tangled cables, excessive slack, and wire breakage from repetitive pulling are among the most common causes of operational disruption and reduced equipment lifespan. Standard power cables simply cannot handle high-frequency movement demands. That's why professional equipment manufacturers trust CHAN MING to support critical wiring components like the Coiled Power Cable (Spring Cable / Retractable Cable).

We deeply understand the industrial and medical industries' extreme demands for wire durability, flexibility, and operational safety. The partner you need doesn't just supply products — we deliver the promise of freedom of movement with absolute peace of mind.

Precision-Engineered for High-Frequency Movement and Space-Constrained Environments

Since 1995, Chan Ming has specialized in custom wiring assembly. Our coiled power cables feature a precision spiral structure with abrasion-resistant, flex-resistant PU or PVC outer jackets and tinned copper conductors for superior temperature resistance and long-term durability. No matter how frequently the cable is stretched and released, it rebounds accurately — effectively saving workspace and extending service life.

They are the ideal wiring solution for the following application environments, including:

  • Industrial Robotic Arms & Automation Equipment
  • Electric Fishing Gear & Outdoor Mobile Devices
  • Medical Instruments & Handheld Diagnostic Equipment
  • Automotive Electronics & In-Vehicle Peripheral Devices

【Product Structure — Detailed Specifications】

1. Spiral Coil Structure

The core advantage of the coiled power cable lies in its precisely wound spiral structure, which delivers outstanding elasticity and rebound force. The natural length (retracted state) and maximum extended length can be configured to meet the specific range-of-motion requirements of different equipment — while preventing cable accumulation and tangling that interfere with operations.

2. Outer Jacket Material

Two primary jacket options are available depending on the application environment. PU (Polyurethane) offers superior abrasion resistance, making it ideal for high-intensity industrial machinery applications. PVC provides excellent flex resistance and cost efficiency, suitable for general equipment and consumer applications. Both options are available in UL-compliant specifications to ensure operational safety.

3. Internal Conductor

Tinned copper conductors are used internally to enhance temperature resistance and oxidation resistance, ensuring that electrical performance remains stable over extended periods of repetitive stretching. The multi-strand twisted construction further improves cable flexibility and effectively resists fatigue fracture caused by repeated bending cycles.

4. Manufacturing Process Highlights

Chan Ming applies strict control over key manufacturing processes for every coiled power cable:

  • Spiral Winding Precision: Pitch and coil diameter consistency controlled to ensure uniform and stable rebound force throughout the cable's length
  • Jacket Formation Quality: PU / PVC jacket thickness maintained uniformly, free from surface bubbles or defects
  • Terminal Crimping Quality: Precision crimping machines used to ensure every crimp point meets pull force and continuity requirements
  • Retraction Performance Testing: Repeated stretch-and-release cycle testing performed under simulated real-world conditions to verify rebound life meets specifications
  • Electrical Testing: Every cable passes Continuity Testing, Hi-Pot (High Voltage) Testing, and Insulation Resistance Testing
