What are the causes of aging of terminal blocks


Abstract: At present, some terminal blocks are often aging after being used for a period of time, which will seriously affect their effect. What are the causes of aging of terminal blocks? The following is a brief analysis of Hengzhuneng.
Three major causes of aging of terminal blocks
Generally speaking, the main reasons for aging of terminal blocks are as follows:
1、 Environment and temperature
The external environment and heat source where the terminal is located will also lead to excessive temperature, insulation breakdown, and even explosion and fire of the terminal.
2、 Chemical corrosion
The insulation material of the terminal housing is subject to chemical corrosion or electrolytic corrosion for a long time, which leads to the failure of the protective layer, the reduction of insulation, and the aging of the terminal.
3、 Long time overload operation
Due to the thermal effect of the current, the load current must cause heating when passing through the terminal, which will increase the temperature of the terminal. The excessive temperature will accelerate the aging of the insulation, especially in summer.
