This retractable spiral (coiled/spring‑type) extension cable adopts polyurethane (PU) outer jacket. It can stretch freely when pulled and automatically retract back to spiral shape after releasing force, effectively avoid wire tangling and save space.
It has good heat‑resistance, abrasion‑resistance and anti‑aging performance. Available for power transmission or mixed power‑signal wiring. Customizable conductor count, wire gauge, stretched length, retracted length and bare tin‑dipped ends or assembled with various connectors. Suitable for mobile working scenarios where cables need to extend and retract repeatedly.

FAQ
Q1: How long can the spiral cable stretch?
A: The stretch ratio is normally 1:3 to 1:5. For example, 0.3 m original coil length can stretch to 0.9‑1.5 m. Excessive over‑stretching will reduce service life.
Q2: What is the difference between PU spiral cable and PVC spiral cable?
A: PU jacket has better elasticity, wear‑resistance and oil resistance. PVC is cheaper but poorer in elasticity and easy to harden after long‑time use.
Q3: Can spiral cables be used for high‑power loads?
A: It depends on wire gauge. Spiral cables are mostly used for low‑to‑medium power or signal applications. Select thicker AWG for higher current.
Q4: Is this cable waterproof?
A: Standard PU spiral cable is splash‑resistant but not fully waterproof. For continuous underwater use, special waterproof version is required.
Q5: Will the spring shape deform permanently?
A: Do not pull beyond rated maximum stretch length and avoid long‑term full‑stretching status, so as to prevent permanent deformation.
