QZY-2/180 Direct Welded Copper Round Wire

See the relevant product standards for weight loss. The pinhole test can be
found in the relevant product standards.
The type of packaging and packaging may affect certain properties of the
enameled wire, such as resilience. Therefore, the type of packaging (such as
the type of delivery reel) should be negotiated between the supplier and the
purchaser to determine that the enameled wire should be wound evenly and
tightly on the delivery reel or placed in the container. Unless there is
agreement between the supplier and the buyer, there should be no more than one
line of enameled wire in the delivery reel or container. When there is more
than one line segment, the supplier and the buyer shall agree to mark the
length of the line segment on the label and/or mark the package. When the
enameled wire is delivered in a loop, the size and maximum weight of the loop
shall be determined by the supplier and the buyer. Any additional protection on
the coil
