0.75mm2 Good Elasticity Spiral Coiled Power Cable Spring Electrical Cables for Electronic Equipment
1. Structure and Materials
1.1 Physical Structure
Spiral winding design: The cable has a tight spring-like structure, which can be stretched longitudinally (such as 2-3 times the stretched length when contracted) and automatically rebound, which is suitable for dynamic expansion and contraction scenarios.
Pitch: The pitch of the spiral affects the expansion rate and flexibility (usually 3-5 times the wire diameter).
Winding direction: divided into left-handed (CCW) and right-handed (CW), which needs to be selected according to the direction of the device interface.
1.2 Conductor and insulation
Conductor: Multiple strands of ultra-fine copper wire are twisted (such as 0.08mm² to 4mm² cross-sectional area) to improve flexibility and fatigue resistance. Tinned copper (anti-oxidation) or silver-copper alloy (high-frequency application) can be selected.
Insulation layer:
PVC: economical and general, acid and alkali resistant.
TPU/TPE: high elasticity, wear resistance, suitable for industrial environments.
1.3 Shielding and protection
Shielding layer (EMI/RFI protection):
Aluminum foil shielding (lightweight), copper braided shielding (high-frequency anti-interference).
Double shielding structure (aluminum foil + copper mesh) for highly sensitive signal transmission.
Sheath: flame retardant (UL94 V0), oil-proof (ISO 6722), UV-resistant (outdoor application) are optional.
2. Electrical and mechanical properties
2.1 Electrical parameters
Rated voltage: 300V (conventional), 600V (industrial high voltage model).
Current capacity: 1A (signal line) to 20A (power line), depending on the cross-sectional area.
Impedance and attenuation: high-frequency models (such as USB 3.0/HDMI) require controlled impedance (90Ω±15%).
2.2 Mechanical properties
Extension life: >1 million cycles (such as igus® Chainflex series).
Bending radius: ≥7.5×wire diameter for dynamic application, ≥5×wire diameter for static application.
Tensile strength: ≥50N (conventional) to 200N (reinforced).
2.3 Environmental adaptability
Temperature range:
Standard type: -40°C to +80°C.
High temperature resistant type: -60°C to +200°C (silicone sheath).
Protection level: IP67 (dustproof and waterproof), IP69K (high pressure washing).
3. Typical application areas
3.1 Industrial automation
Robotic arm: joint connection line, resistant to high-frequency bending (such as KUKA/Fanuc robots).
Sensor wiring: winding design to avoid cable entanglement (such as photoelectric sensors, encoders).
3.2 Medical equipment
Sterilizable cable: silicone sheath withstands gamma ray or EO gas sterilization.
Monitor: spiral structure prevents pulling and falling off (such as ECG lead wire).
3.3 Consumer electronics
Telephone handset cable: spiral cable (RJ11 interface) of traditional POTS phone.
Retractable charging cable: portable design of Type-C/Lightning interface.
3.4 Automotive and Aviation
Steering wheel harness: oil and high temperature resistance (compliant with ISO 6722).
Airborne equipment: lightweight shielded wire (such as MIL-DTL-27500 standard).
4. Advantages
Space efficiency: The telescopic feature saves wiring space and avoids redundant wire length.
Durability: The bending life far exceeds that of ordinary flexible cables.
Signal integrity: The shielding design ensures high-frequency transmission (such as 5Ghz HDMI signal).
5. Selection Guide
1. Clear requirements:
Dynamic/static use? High-frequency signal or power transmission?
2. Environmental factors:
Does it require oil resistance, high temperature resistance or sterility certification (such as USP Class VI)?
3. Certification standards:
Industrial: UL/CE, RoHS.
Medical: ISO 13485, FDA.
Using thickened oxygen free copper wire core effectively reduces resistance and makes the circuit less prone to overheating. Simultaneously coated with a fireproof layer, it remains safe and durable even in high-temperature and dry environments. Bold thread body, sturdy and resistant to bending, will not break after long-term use.
