4 Core Spiral Coiled Cable 4Pin Spring Electrical Wire High Elasticity Spiral Telescopic Cable
1. Product core positioning
The four-core spiral cable is a composite cable designed for scenarios that require synchronous transmission of multiple signals/power and take into account scalability. It adopts a highly elastic spiral structure (can be stretched to 3 times the length) and a four-independent insulated core design. It is widely used in composite scenarios that require synchronous transmission of power + signals, such as automation equipment, medical instruments and mobile control systems.
2. Six core advantages
Intelligent telescopic: 1m (contraction) -3m (extension) freely adjustable
Four independent cores: 4×0.75mm² color-coded core wires (customizable combination)
Composite transmission: supports power + signal synchronous transmission (up to 50V/300V isolation)
Super strong protection: double-layer spiral sheath (inner insulation layer + outer wear-resistant layer)
Quick connection: pre-tinned wire end (stripping length can be customized)
Industrial grade life: 50,000 telescopic cycle tests
3. Technical specification parameter table

Test equipment: Mobile detection equipment composite wiring
5. Purchase decision guide
| Application requirements | Recommended model | Key features |
| General industrial use | 4C-SP-075 | basic model/0.75mm² four-core |
| Medical equipment use | 4C-SP-MED | silicone insulation/biocompatibility certification |
| Outdoor harsh environment | 4C-SP-IP67 | waterproof/UV-resistant orange sheath |
| High-frequency signal transmission | 4C-SP-HF | with aluminum foil shielding layer/impedance matching |
6. Safety use specifications
Installation requirements:
Before the first use, it is necessary to fully retract and retract 5 times to activate the elasticity
Minimum installation radius ≥ 8 times the wire diameter
Operation taboos:
It is forbidden to mix cores of different voltage levels
Avoid long-term contact with hydraulic oil
Maintenance points:
Check whether the sheath is cracked every month
Test the insulation resistance between cores every quarter
7. Key technology FAQ
Q: Can it replace ordinary multi-core wires?
A: Suitable for mobile scenes, straight lines are recommended for fixed installation
Q: Can each core carry different voltages?
A: Ensure that the voltage difference is ≤300V and insulation isolation is done well
Q: How to solve the interference of signal transmission?
A: Optional shielded version (add aluminum foil + braided mesh)
Q: Performance changes under extreme temperatures?
A: The elasticity is reduced by 15% at -30ºC, and the current carrying capacity is reduced by 20% at +80ºC
8. Product innovation highlights
Structural innovation: Four-core spiral symmetrical arrangement (patented design) reduces interference
Material breakthrough: Cold-resistant TPE sheath passes the -50ºC test
Intelligent monitoring: Optional version with expansion counter (LED display)
