UL electronic wires models include UL1007, UL1015, UL1032 / 1028, UL1095, UL1569, UL1571, UL1617 / 1618, UL1061, UL1430 / 1431, UL3302, UL3385, UL10368 etc.
The main reasons for UL electronic wire aging are as follows:
1. Environment and temperature: mainly the external environment and heat source where the UL electronic wire is located will cause the temperature to be too high, insulation breakdown, or even cause an explosion and fire;
2. Chemical corrosion: When the UL the electronic wire is placed in the place of acid-base action, it will often become the outer protective layer of the electronic wire to be corroded. The protective layer will suffer chemical corrosion or electrolytic corrosion for a long time, resulting in the failure of the protective layer and the reduction of insulation Causing cable failure;
3. External force damage: mostly caused by mechanical damage;
4. Cable joint failure: Generally, the cable joint failure is caused by poor construction of the operator. This phenomenon often occurs;
5. Long-term overload operation: due to the thermal effect of the current, the conductor heats up when the load current passes through the cable. At the same time, the skin effect of the charge, the eddy current loss of the steel armor, and the insulation medium loss will also generate additional heat, which will increase the cable temperature;
6. Insulation dampness: It usually occurs at the cable joints in direct buried or drain pipes. This phenomenon is also very common.
