Will there be interference if the background music broadcast cable and the weak current system network cable in the building are on the same bridge?

No, weak current network cables are twisted pairs. Twisting the signal wires means twisting two insulated copper wires together at a certain density, which can reduce the degree of signal interference. Therefore, the broadcast line The electromagnetic radiation of the network cable hardly affects the transmission quality of the network cable, and the weak current signal of the network cable is very low, and the impact on other network cables is also very low. Therefore, there will be no interference if these two lines are placed on the same bridge.
