What is the role of the two-color wire and monochrome wire?
1. Birds are just standing on a wire can not form a loop so there is no electric shock. 2. Birds feet from the distance even in the high voltage line will not form a step voltage.
Strong electricity for the AC, will produce electromagnetic waves, interference with the weak. Strong current (alternating current) generated by the magnetic field generated by the adjacent wire current, although the current is weak, but enough to affect the same weak weak current, resulting in accidents
