The function of the twisted pair cable is to make the noise generated by external interference on the two wires the same, so that the subsequent differential circuit can extract useful signals. The two insulated copper wires are twisted together at a certain density. The radio waves radiated by each wire during transmission will be offset by the radio waves emitted by the other wire, effectively reducing the degree of signal interference. It can not only resist part of the electromagnetic wave interference from the outside world, but also reduce the mutual interference between multiple pairs of twisted wires.

However, due to the influence of climate and environment, twisted pair cables are often used in extremely cold and harsh environments, including lighting lines. However, in extremely cold weather, twisted pair cables are easily unable to transmit signals normally due to excessive cold, which brings inconvenience to the operation of lighting lines.
