How To Effectively Reduce The Oxidation Of Bare Copper Wire

In principle, the metal copper for cables mainly has physical methods to block the contact between copper and humid air, cathodic protection redox method to prevent copper conductor oxidation, chemical method to produce a passivation film on the surface of the copper conductor to prevent oxidation, or spray special liquid on the surface of the conductor for protection. Therefore, the following measures can reduce the chance of oxidation of copper conductors:
1. Select high-quality metal copper rod, standardize the supplier's transportation, delivery process and system, after the copper rod arrives at the company, take transparent plastic film sealing measures, copper conductor drawing, stranding should take transparent plastic film sealing measures;
2. Adopt a suitable bare copper wire drawing process, regularly check the annealed parts of the wire drawing machine, give preference to the drawing oil containing antioxidants, regularly check the concentration of emulsion, and replace it in advance before the expiration of the shelf life;
3. The bare copper wire stranding and extrusion insulation process adopts passivation treatment technology;
4. Establish quality awareness, strengthen business training, and let the operators of the above processes understand the adverse consequences caused by the oxidation of bare copper wire.
