Mineral cables: Common causes of wire and cable failures
It is understood that the direct cause of wire and cable failures is the reduction and breakdown of insulation capacity. There are many factors that lead to the reduction of insulation sensitivity. Based on the practical operation and management experience of enterprises, the following different situations are summarized. Hongsheng Wire and Cable Co., Ltd.'s editor will take you to understand. 1. External damage. 2. Insulation moisture. For example: unqualified wire and cable connectors, in humid climates, joints can produce water or water vapor, under the action of the electric field for a long time, layered water tree mixing, gradually reducing the insulation strength, causing damage to the cable failure.
Mineral cable It is understood that the direct cause of wire and cable failures is the reduction and breakdown of insulation capacity. There are many factors that lead to the reduction of insulation sensitivity. Based on the actual operation and management experience of enterprises, the following different situations are summarized. Hongsheng Wire and Cable Co., Ltd. Let's take a look.
1. External damage.
2. Insulation moisture. For example: unqualified wire and cable connectors, in humid climates, the joints can produce water or water vapor, and under the action of the electric field for a long time r layered water tree mixture, the insulation strength gradually causes damage to the cable failure.
3. Mineral cable Chemical structural corrosion. In areas where acid-base promotes each other, due to the long-term development of enterprises, various chemical or electrochemical corrosion of armored cables, conductors or corrosion protection layers, the outer protection layer can often cause, leading to poor insulation of the protection layer, and will also affect the network cable failure.
4. Long-term overload operation. Due to the effect of current, the thermal effect of the load current passing through the wire and cable inevitably leads to conductor heating. At the same time, the skin effect and eddy current loss of the charge, and the dielectric loss of the steel armor will also generate additional heat, increasing the temperature of the cable.
5. Cable joint failure. Wire and cable joints are often the weak link that causes cable joint failure and is often overlooked. In the manufacturing method of cable joints, if the crimping is not tight and the heating is insufficient, the insulation of the cable joints will be reduced, causing accidents.
