Questions and answers about common shielded wiring systems such as lightning protection, grounding, and safety(2)
Q: My unshielded twisted pair system is protected by wired pairing. Is this efficient enough to suppress interference?
Answer: No. Mutual twisting can reduce interference, but it cannot effectively eliminate interference. Mutual twisting cannot suppress electromagnetic radiation. If the cable is stretched or flattened during installation, this will be more serious. Because the geometry is no longer uniform.
Q: I have an unshielded twisted pair system and want to improve my EMC performance. how should I do?
Answer: The most effective way is to incorporate cables and components into a shielded environment. This environment can be shielded cable ducts and channels. Shielded racks and patch panels can provide some basic protection. Note: All components must be connected to the equipotential bonding system.
Question: I have a shielded system and want to use an unshielded patch cord. is it possible?
Answer: The system can work as if it is equipped with a shielded patch cord. But because there is no complete connection to the ground (only connected on the wiring board), there is no ability to suppress electromagnetic interference. Therefore, shielded jumpers should always be used.
Q: What is the difference between grounding and grounding?
Answer: There is no difference, just two words of the same object.
