Frequently Asked Questions
What is the primary purpose of this cable?
Designed for transmitting low-voltage signals in industrial control systems, automation, and computer networks, with enhanced EMI protection.
Why is copper braid shielding used?
The copper braid provides excellent electromagnetic interference (EMI) and radio frequency interference (RFI) shielding, ensuring signal integrity in noisy environments.
Can it be used outdoors or in damp environments?
Yes, the PVC sheath provides weather resistance, but for extreme conditions, additional protection (e.g., conduit or armored versions) may be required.
How does it compare to unshielded cables?
Shielded cables offer superior noise immunity and signal clarity, making them ideal for sensitive electronic equipment and high-interference areas.
What bending radius should be maintained during installation?
Follow manufacturer guidelines (usually 4-6 times the cable diameter) to avoid damaging the conductors or shielding.
How do I ensure proper termination of the shielding?
Use appropriate shielding termination techniques (e.g., grounding clips, connectors with integrated shields) to maintain EMI effectiveness.
