What percentage of copper is recycled from scrap cable wires mainly decided by what copper content in scrap cable wires and what percentage can be recycled from total copper content inside of cable wire.
First we look how to calculate the copper content in scrap cable wires?
As the universal algorithm of national standard: copper wire cable diameter*8.9*copper wire cable length for meters/1000. According to this formula, we can calculate the copper content by weight in the cable. Of course, this just one standard to estimate the approximate copper content, the most accurate method of measuring copper content is take one meter of cable to weighing, after peeling the plastic skin of the cable, then reweighted the net weight of copper. So we will know actual content of copper in one meter scrap cable wires. And we already have some data like: YJV copper cable wires: copper weighs at 87% around, YJV Armour: 75% around, VV cable: 78% around, YC Heavy Rubber Cover: Copper weight at 50% around. Above is the approximate content of medium-sized copper. The smaller cable cross section, the higher insulation content, the lower unit copper weight.
There also have the cable use the copper-clad Aluminum composites, it is difficult to calculate the copper content, we can try to know the thickness and width of the copper strip before compounding and the diameter of the aluminum rod, it is will better to calculate the copper content, the different diameter of copper clad aluminum, the copper content is not same.
Last how much percentage can be recycled from total copper content inside of cable wire?
DOING company is very confident to say 95-98% copper(Approach 100%) can be recycled from scrap cable wires. This data is the result after DOING company’s many times test result by DOING scrap cable wire recycling machine. Main use the technology of copper and plastics separation. DOING copper recycling machine can be achieved that these is no copper in the plastic and no plastic in the copper basically.
