sjow cable is a rubber cable product mainly composed of multiple strands of thin copper wire as conductors, wrapped with rubber insulation for protection. It is also very soft and movable for siow wire, and can be applied in a wide range of fields. However, copper wire blackening often occurs during use, and there are many reasons for this phenomenon. Let's take a look together below.
1, Reasons for Blackening of sjow Cable Copper Wire
For the phenomenon of copper wire blackening in rubber sheathed cables, it can also be analyzed from this aspect. Many sjow cable manufacturers use ordinary copper rods to make them, which also reaches a copper content of 99%. If the copper wire core of sjow cables is stored in poor environmental conditions or processed under unfavorable conditions, it will cause oxidation of the copper wire core, which will also cause the copper wire to blacken
2, Related to the structure of sjow cable
Another issue is that trace amounts of copper have a significant destructive effect on the rubber. For sjow cables, during the processing and manufacturing process, it also penetrates deep into the insulation rubber through the vulcanization process, which can cause heavy metals to catalyze aging of the sjow cable's rubber and lead to its stickiness.
3, It is also closely related to the processing technology of the sjow cable
In addition, the blackening of the copper wire of the sjow cable is also closely related to the processing technology. The rubber material is mainly mixed with natural rubber and styrene butadiene rubber during processing, which has high plasticity for natural rubber. If the temperature control is not good throughout the entire processing, different reactions will occur, which will have a great impact on the processing and production of SJOW cables and cause such imagination to occur. So, when manufacturers complete their processing and production, they also need to make significant changes in the processing technology to produce electric cable products that better meet our needs.
