How To Reduce The Chance Of Copper Conductor Oxidation?

May. 28, 2019

The copper atom number is 29, belonging to the transition metal, the density is 8.92g/cm3, the melting point is 1083.4°C, and it has good thermal and electrical conductivity. However, in the humid air, the surface of the metal copper reacts with oxygen to form Cu2(OH). 2CO3, that is, patina, usually the copper oxidation in the cable production plant shows that the surface is black, which is the existence of the surface oxidation phenomenon of the copper conductor, which is plagued by many cable companies. As a Fireproof Cable Supplier, we believe that in daily production, the following measures can be taken to reduce the chance of copper conductor oxidation:

Insulated Overhead Power Cable

1. Select high-quality metal copper rods to regulate the transportation and delivery processes and systems of suppliers. After the copper rods are delivered to the company, transparent plastic film sealing measures shall be taken. After the copper conductors are drawn and twisted, transparent plastic film sealing measures shall be taken;

2. Adopt appropriate copper wire drawing process, regularly check the annealing parts of the wire drawing machine, preferentially select the drawing oil containing antioxidant, check the concentration of the emulsion regularly, and replace it before the expiration of the shelf life;

3. The copper wire stranding and extrusion insulation process adopts passivation treatment technology;

4. Establish quality awareness and strengthen business training to make the above process operators aware of the adverse consequences of copper wire oxidation.
