What are the reasons for the reduced insulation of the USB panel mount cable?

USB panel mount cable products are widely used, so there are many types. Today, Xiaobian compiled this article to give a brief introduction to the reasons for the reduction of cable insulation.

1. External force damage, quite a few USB panel mount cable failures are caused by mechanical damage.

2. The insulation is damp, the USB panel mount cable connector is not up to standard, and the connector is made in a humid climate. This may lead to water or water vapor into the connector. After a long time, it is easy to form water branches under the action of the electric field, and gradually Damage the cable insulation strength and cause failure.

3. Chemical corrosion, USB panel mount cable is used in acid and alkali environment, which may cause the cable armor, lead and outer sheath to be corroded, and the protective layer may suffer from chemical corrosion and electrolytic corrosion for a long time. The protective layer fails and the insulation decreases, which can lead to cable failure.

4. Long-term overload operation, overload operation, because of the current heating effect, the load current will cause the conductor to heat up when the load current passes through the USB panel mount cable, the skin effect of the charge, the eddy current loss of the steel armor, and the loss of the insulating medium will also generate additional heat. This will increase the temperature of the cable. During long-term overload operation, the excessive temperature will accelerate the aging of the insulation, which can easily lead to the breakdown of the insulation. Therefore, in the hot summer, the temperature rise of the cable can easily lead to the breakdown of the weak insulation of the cable, so there are many cable faults in the summer.

5. USB panel mount cable connector failure, the cable connector is the weakest link in the cable line, because the cable connector failure caused by poor construction often occurs. In the process of making cable joints, if there are reasons such as insufficient joint crimping and insufficient heating, these will reduce the insulation of the cable head and cause accidents.

6. Environment and temperature, the external environment and heat source where the USB panel mount cable is located may cause the cable temperature to be too high, insulation breakdown and explosion and fire.

7. Other factors, normal aging of the USB panel mount cable body or natural disasters and other reasons.
