Abstract: at present, some terminals are often aged after being used for a period of time, which will seriously affect their effect. So what are the causes of terminal aging? The following is a brief analysis of Ningbo Hongyi Xiaobian.
Three causes of terminal aging
Generally speaking, the main causes of terminal aging are as follows:
1、 Environment and temperature
The external environment and heat source of the wiring terminal will also become too high temperature of the wiring terminal, insulation breakdown, and even explosion and fire.
2、 Chemical corrosion
Due to long-term chemical corrosion or electrolytic corrosion of the insulating material of the terminal housing, the protective layer will fail, the insulation will be reduced, and the aging of the terminal will be exacerbated.
3、 Long time overload operation
Due to the thermal effect of current, when the load current passes through the terminal, it will inevitably lead to heating, which will increase the temperature of the terminal, and too high temperature will accelerate the aging of insulation, especially in summer.
