And audio sector conversations often refers to the question: are said to be 8GA power cable, why are there per disc to 300 blocks, each of the 200 block of only 100 block?
This question is very good, because so far the domestic audio wire has not been harmonized standards. But formal manufacturers will refer to existing international standards (i.e.: A regulation and the regulation, in annex B) temporarily as their production standards. So we have a differential power quality standards.
Formal power cables, insulated rubber antioxidant with new PVC plastic, core conductor using isolated Air Act manufactured oxygen-free copper (OFC) or tinned copper, and silver-coated copper. After precision equipment precision manufacturing.
High-quality power cable insulation, good resistance to heat not only, but also core conductors used seven twisted pair or braided, so that they will have sufficient density to reduce resistance, capacitance and inductance, thus the output enough electricity flow.
While other manufacturers are not formal, insulated rubber is recycled PVC plastic, core conductor secondary copper or copper, aluminum, or wire, or a mixture. It is well known. These types of conductor relative oxygen-free copper (OFC) of internal resistance, voltage drop is much greater. This only 12V car power supply is very harmful.
Judgment on the merits of the power line, rather than its apparent size, more important is to look inside copper conductor thickness and quality. Because of the power line would have extremely thick rubber inside of the copper conductor are disproportionate, very fine. So mainly depends on the size of the cut surface of the copper conductor.
Also see each line the length of the actual and nominal is consistent, there are no short pounds short of two phenomena. Talking about this, the opening of the problem is solved.
