Why can copper wire explosion proof?
Multiple thin copper wire, soft wire, easy to bend,Compared to a single strand line, the equivalent resistance of a plurality of thin copper wire leads is smaller than the same cross-sectional area
Copper metal has excellent electrical conductivityThe core of a cable usually consists of a thick copper wire and a thin copper wire
The single strand of thick copper wire, the wire is relatively hard, cheaper, and more used in no need to move places, such as underground, wall wiring
