Must see! Six common cable fault problems

Insulation damage is a common problem in cable faults. The insulation layer, serving as a protective barrier for cables, is supposed to effectively prevent current leakage and short circuits. However, during long-term use, natural factors have been constantly eroding it. In a humid environment, after insulating materials absorb water, their insulating effect is significantly reduced, just like a cotton-padded coat soaked by rain, gradually losing its function of keeping warm and providing protection. In high or low temperature environments, materials become soft or hard and are prone to falling off, providing an opportunity for electric current to take advantage and subsequently causing malfunctions.

Cable joints are the weak links in the system, and joint faults cannot be ignored. If there is poor insulation, unstable connection at the joint, or it is affected by environmental factors, it may cause a malfunction. When the seal is not tight, moisture and dampness will seep in and erode the insulating material. Loose connections will lead to increased resistance, intensified heating, and eventually may cause local heating and smoking of the cable, and even trigger a fire. This is just like the connection points of a bridge. If they are not stable enough, problems may arise at any time, affecting the smoothness of the entire traffic.

Overloading operation is the invisible killer of cable faults. Each type of cable has its rated load limit. Once it is overloaded, the interior will overheat, accelerating the aging of insulation materials and damage to conductors. Long-term overloading operation not only reduces the transmission capacity of cables but may also cause safety accidents such as fires. This is just like when a person works beyond their capacity for a long time, their body will gradually be unable to take it, and the cables will also break down when they are overwhelmed.

Mechanical damage is an external injury that cables are prone to encounter during installation and laying. If operations such as dragging and lifting are not handled with care, external damage may occur, leading to the breakage of the insulation layer and causing leakage or short circuit. When laying cables, every move must be done with caution, just like taking care of a precious work of art. A slight oversight may leave irreparable scars.

Environmental factors are the chronic poison of cables. Groundwater, soil pH, corrosive gases, etc. may all cause corrosion to cables. Especially for underground cables, water infiltration can lead to the degradation of insulating materials, causing short circuits or leakage. Environmental factors such as high temperature, humidity and chemical corrosion are like invisible knives of time, accelerating the aging and damage of cables.

Natural aging is an inescapable fate for cables. As the usage time increases, the physical and chemical properties of insulating materials and conductors change, their insulation and conductivity decline, and faults follow. Just as people's physical functions decline as they age, cables also gradually age over the passage of time.

In the face of these potential faults, we are not helpless. During the installation and laying of cables, operations must be strictly carried out in accordance with the specifications to avoid mechanical damage. Regularly inspect and maintain the cables to promptly identify issues such as loose joints and aging insulation. Plan the load of the cables reasonably to avoid overloading operation; When selecting cables, fully consider environmental factors and choose materials that are corrosion-resistant and anti-aging.

Cable safety is related to urban development and the well-being of the people. It is the cornerstone of the normal operation of the city and the guarantee of a better life for the residents. Let's, with a strong sense of responsibility and mission, safeguard these urban blood vessels, ensuring that electricity is safely and stably delivered to every corner, lighting up every night of the city, and contributing to the prosperous development of the city and the happy life of its residents.
