I. External force damage

External force damage is a common cause of failure. At present, the products of UL power cord manufacturers have been widely spread to all corners of the city. Once a relatively large external force occurs, the power cord will be damaged. For example, the common power outages may be caused by the machine's failure to properly plan and dig the power lines directly during the construction of urban roads, resulting in power outages in some urban areas.

Second, the corrosion of power lines by external environment

With the destruction of the environment, various chemical components in the air will corrode the power cords to varying degrees. Acid rain is one of the elements of corrosion. With the industrial processing, various harmful gases have not been processed, causing them to be emitted into the atmosphere. Sulfur dioxide gas combines with moisture in the air to form sulfuric acid. Once it starts to rain, the rain will slowly corrode the power cord. Over time, the power cord will have various failures due to corrosion.

Three, over operations

People will experience fatigue if they are in a long-term working condition, and power cords are no exception. Excessive operation for a long time will cause the power cord to start heating. The heat will accelerate the aging of the power cord and even break down the insulation. There are particularly many wire failures in summer. In addition to excessive operation, the overall weather in summer is relatively high, which is not conducive to the long-term operation of the power line.

Four, insulation and moisture

Ul power cord manufacturers remind you that it is also very common for power cords to malfunction due to damp insulation. Over time, the inner and outer sheaths of the power cord will age, especially under harsh environmental conditions, and the probability of moisture insulation is very high. For example, the power cord buried in the ground for a long time will be corroded by the soil and various failures will occur.

Five, chemical corrosion

With the destruction of the environment, today's rainwater is acid. Products of Ul power cord manufacturers will experience various kinds of chemical corrosion after long-term exposure to sunlight and rain outdoors. Of course, it is not ruled out that the environment in which the power cord is used has an acid-base effect, which will cause the armor, lead skin or outer sheath to be corroded, and the power cord will lose its original function.

The above is the situation that ul power cords related to ul power cord manufacturers will appear in outdoor use. Hope to help everyone.
