The causes of aging of popular science and technology UL electronic wires manufacturers of UL electronic wires are as follows:

1. UL electronic wire environment and temperature

The external environment and heat source where the cable is located will also become too high in cable temperature, insulation breakdown, and even explosion and fire.

2. Chemical corrosion

The cable is directly buried in the area with acid and alkali, which often becomes the cable's armor, lead sheath or outer sheath is corroded. The protective layer is subject to long-term chemical or electrolytic corrosion, which causes the protective layer to fail and the insulation to be reduced It will also cause cable failure.

3. External force damage

Judging from the operation analysis in recent years, especially in Hai Pudong, where the economy is developing rapidly, a lot of cable faults are now caused by mechanical damage.

4, the cable connector is faulty

ul electronic wire manufacturers remind you that the cable connector is the weakest link in the cable line. Cable connector failures caused by direct negligence of personnel (poor construction) often occur. In the process of making cable joints, if the construction staff has any original network, such as inadequate crimping or insufficient heating, all of them will cause the insulation of the cable head to decrease, which will cause an accident.

5. Long-term overload operation of UL electronic lines

Overload operation, due to the thermal effect of the current, the load current must cause the conductor to heat up when the load current passes through the cable. At the same time, the skin effect of the charge and the eddy current loss and insulation loss of the steel armor will also generate additional heat, which will cause the cable temperature to rise. high. During long-term overload operation, excessive temperature will accelerate the aging of the insulation, and even the insulation will be broken down. Especially in the hot summer, the temperature rise of the cable often causes the weak insulation of the cable to be broken down first, so in the summer, the cable has a lot of failures.

6, UL electronic wire insulation moisture

This symptom is also very common, and it usually occurs at the cable joint in the buried or drain pipe.

The above is the reason for the aging of the 6 types of UL electronic wires shared by the popular science of UL electronic wire manufacturers. I hope to help everyone.
