Cable copper heart of the cross-sectional area, but the copper wire inside there are thick and thin, I would like to ask what is the difference and influence?
Ease of use, there is no doubt that many strands of wire are more flexible and adaptable, and all home appliance power lines are made of multiple strands. As a result of metal fatigue, single strand wires are easy to break after long bending
1. skin effect, because of skin effect, the equivalent resistance of multi strands wire under high frequency is less than single strand guide. High frequency transmission can only use multiple wires, the smaller the better2. manufacturing cost multiple lead cost is higher than single strand wire, so in some need not move occasions (such as building internal power leads) more use of single stranded wire
The advantage of a single core line is that it is easy to shape. It is easy to make it flat and vertical, while multicore wires are not so beautiful. The disadvantage of the single core line is that the crimping is inconvenient, and if you don't pay attention to it, it will fall off easily.
