What the meaning of 2-UEW and 1-PEW that indicate on manufacturer's label? And how the different?2-UEW means that Polyurethane in coating on the wire. 1-PEW means that Polyester in coating on the wire. Numbers on the front is indicated level of thickness of liquid varnish-coated wire, it is separated as the Class. Class 0 means the thickest class of liquid varnish to the wire. Class 1 means the thickness of liquid varnish is less than Class 0. Class 2 means the thickness of liquid varnish is less than Class 1. Class 3 means the least thickness of liquid varnish to the wire. According to the requirements of JIS Standards and Industrial Standards (TIS).

How different between coatings varnish on the small diameter copper wire and the larger diameter wire?In general, the method of coating copper wire is the same. However, the diameter size of copper wire is used in different machine and divided as following: Copper wire diameter from 0.04 mm. - 0.75 mm. Coating varnish in horizontal machine Copper wire diameter from 0.80 mm. - 2.60 mm. Coating varnish in vertical machine For the large diameter copper wire, they cannot be coated in horizontal machine due to the large diameter and the heavy weight. It will not steady and the varnish on the copper wire surface will be a wave and not smooth.
