Is the communication cable live? What is the voltage? Can the electricity be dead?
Communication cables are electrically charged, the cable is busy with more than 100 V, but the capacity is small, not dead, but it can be shot down from the sky and killed.
Communication cable of course, live, voltage below 36 volts, is not dead electricity
If the cable is not charged, if it is, then the ordinary cable. Charged to, how many volts, not easy to say. Like the home phone ringing voltage, call voltage, standby voltage are unequal. General Electric dead people. But as the environment, sometimes also the electric welder dead. But it's definitely better than voltage electric welder two times higher. Be careful.
