Features of Spiral Shielded Cable
Spiral shielding design: The copper wire shielding layer is wrapped around the conductor in a spiral manner, providing good anti-interference ability.
Low-noise transmission: Reduces electromagnetic interference (EMI) and radio frequency interference (RFI) to ensure stable signals.
Flexible and easy to bend: Suitable for complex wiring environments and easy installation.
Durable PVC sheath: Prevents external damage and increases service life.
Compliant with UL standards: Passed UL 758, UL 1581 tests, and meets UL VW-1SC vertical flame retardant standards.
Advantages of Spiral Shielded Cable
High efficiency and anti-interference: The spiral shielding structure is more flexible than the braided shielding and is suitable for low-frequency signal applications.
Stable transmission: Reduce signal loss and improve audio and data transmission quality.
Good flexibility: Easier to bend than traditional shielded cables, suitable for dynamic applications.
Safe and reliable: High temperature resistance of 80℃, rated voltage of 30V, meets safety standards.
Scope of use of Spiral Shielded Cable
Studio equipment: Used for professional recording equipment to ensure low noise and high-fidelity audio transmission.

FAQ
Q1: What is spiral shielding? What is its function?
A1: Spiral shielding refers to tinned copper wire or bare copper wire wrapped in a spiral manner, which can effectively reduce electromagnetic interference (EMI) and improve signal quality. It is suitable for low-frequency signal transmission.
Q2: Is this cable suitable for high-frequency signal transmission?
A2: Spiral shielding is more suitable for low-frequency signals. Braided shielding or aluminum foil shielding cables are recommended for high-frequency applications.
Q3: Is this cable UL certified?
A3: Yes, it complies with UL 2854 standard and has passed UL 758, UL 1581 test and meets UL VW-1SC flame retardant standard.
Q4: Is this cable suitable for outdoor use?
A4: The PVC jacket has certain weather resistance, but if it is exposed to UV and humid environment for a long time, it is recommended to choose a model with an additional protective layer.
Q5: How to extend the service life of this cable?
A5: Avoid direct sunlight, humid and chemical corrosion environment when storing, and avoid excessive bending during installation to extend the service life.
Q6: What is the difference between spiral shielding and braided shielding?
A6: Spiral shielding is more flexible and suitable for dynamic applications, but the shielding effect is slightly weaker than braided shielding. Braided shielding is suitable for high-frequency environments and provides stronger anti-interference ability.
Q7: Is this cable suitable for audio equipment?
A7: Yes, UL 2854 multi-core shielded cable can be used in recording studios, sound systems, etc. to ensure high-fidelity audio signal transmission and reduce electromagnetic interference.
