The 6 most common causes of circuit failures caused by hook up wire

In recent years, in the entire maintenance market, most of the failures of electronic products are caused by the aging of the internal structure of the UL certified hook up wire, especially the damage to the insulation layer of the hook up wire. This is almost the case throughout the entire maintenance industry. Let's take a look at the reasons for the aging of UL standard electronic wires or hook up wires.

Environment temperature

The external environment of the UL certified electronic wire and the proximity of the heat source will also cause the UL standard hook up wire to be prone to overheating, softening or breakdown of the insulator, and even explosion and fire.

Chemical corrosion

The UL certified electronic wire, such as the common used UL1007 or UL1015, both are directly laid in the acid-base effect area.No any other special protection measure, it will cause the outer sheath and insulation to be easily corroded, the protective layer will be subject to chemical corrosion or long-term electrolytic corrosion, resulting in the failure of the protective layer, the reduction of insulation performance, and the short circuit of the UL certified hook up wire.

Damage by the external force

From the industry analysis in recent years, under the background of rapid economic development, there are quite a few electrical failures caused by damage to the UL standard electronic wires inside the machinery.

Wire connector fault

The UL certified hook up wire connector is the weakest link in the UL standard electronic wire conductor. Due to the direct negligence of personnel and improper laying, the failure of UL certified electronic wire connector often occurs. In the process of making UL certified hook up wire connectors, if there are insufficient connectors, improper connection, etc., it will reduce the safety of use and easily lead to accidents.

Overload operation for long time

Due to the heating effect of the current, when the load current passes through the UL standard electronic wire, the conductor must be heated. At the same time, the skin effect of the electric charge and the insulation loss will also generate additional heat, which will increase the temperature of the cable. In long-term overload operation, excessive temperature will accelerate insulation aging and even insulation breakdown. Especially in hot summer, the temperature rise of the UL certified hook up wire often causes the weak part of the UL standard electronic wire to be broken down first, so in summer, there will be more electrical equipment failures.

Damped Insulation

It is also common for the insulation layer of UL certified hook up wire to be damp, which usually occurs in directly buried cable joints or pipes. For example, substandard wire and cable splices and splices made in wet weather conditions can lead to the ingress of moisture or water vapor into the splices. Because moisture can also conduct electricity, over time, a short circuit will be formed under the action of the electric field, and it will gradually threaten the insulation strength of the cable, resulting in electrical failure.
