Cable storage does not require attention to the environment? The truth is revealed!

In terms of cable storage, many people mistakenly believe that cables are durable industrial products and do not need to pay special attention to the storage environment. In fact, this perception is wrong. During the long-term storage of cables, if the environment is not appropriate, the insulation performance will be reduced, the sheath will age, and even the service life will be affected. Therefore, cable storage needs to meet certain environmental requirements.

Avoid moisture and keep dry and ventilated

The insulation layer and sheath materials of the cable are mostly polyvinyl chloride (PVC), cross-linked polyethylene (XLPE) or rubber materials. Although these materials have certain moisture resistance, they may still absorb moisture, age, and even reduce insulation resistance if they are in a humid environment for a long time. Especially for cables with unsealed exposed ends, their internal conductors are easily oxidized by moisture, affecting the conductivity. Therefore, the warehouse where the cables are stored should be dry and well ventilated to avoid moisture and water accumulation.

Stay away from corrosive substances such as acids, alkalis, and mineral oils

The sheath and insulation layer of the cable are easily corroded by chemicals such as acids, alkalis, and mineral oils, causing the materials to soften and crack, and in severe cases, they will lose their due insulation protection. Therefore, cables should be stored away from chemical reagents, oil and other corrosive substances to avoid degradation of cable performance due to chemical reactions.

Control storage methods to avoid mechanical damage

Cables should be neatly coiled and avoid random stacking to prevent damage to the insulation layer due to extrusion, bending, and excessive stretching. For cables stored for a long time, regular inspections should be carried out to ensure that there is no external damage or environmental changes.

Cable storage is not just about placing it randomly. It must be kept dry and ventilated, away from corrosion sources, and avoid mechanical damage to maintain its electrical performance and service life. Only by storing cables correctly can safe and stable operation be achieved during installation and use. Return to Sohu to see more
