The storage and transportation of power cables are critical to ensuring product quality and safe use. Improper handling can not only degrade the cable's insulation performance but also pose serious safety risks. Therefore, cables must strictly adhere to the following requirements during storage and transportation.
Storage Precautions
Environmental Requirements
The storage area should be dry and well ventilated, and should not come into contact with acids, alkalis, mineral oils, or other corrosive substances.
Harmful gases that can damage insulation or corrode metals should be avoided in the warehouse.
Cable Reel Management
Cable reels must be stored upright; horizontal storage is strictly prohibited.
During storage, reels should be rotated regularly to prevent prolonged moisture buildup on the bottom and pallet rot.
During storage, ensure that the cable ends are properly sealed to prevent moisture intrusion.
Storage Period
The cable storage period is based on the date of delivery and is generally no longer than 18 months, with a maximum of two years.
Transportation Precautions
Loading and Unloading Requirements
During loading and unloading, avoid dropping cable reels from heights, especially in low-temperature environments, to prevent cracking of the sheath or insulation. Do not throw or drag cables for transport.
Lifting Specifications
When lifting, only single reels must be operated; multiple reels must not be lifted simultaneously.
When using a forklift or crane, ensure uniform force to prevent damage to the cable reel.
Transport Protection
Cable reels must be securely fastened to the transport vehicle to prevent tipping or collision.
During transportation in rainy or snowy weather, cables must be covered to prevent water ingress and moisture.
Factors Affecting Service Life
The service life of power cables depends not only on the quality of the product itself but also on the storage, transportation, installation, and operating environment. Prolonged exposure to corrosive gases or humid environments will cause the sheath and insulation layer to gradually age, harden, and crack, eventually losing their insulation properties and posing a safety hazard.
Power cables must be stored in a manner that protects them from moisture, corrosion, and sunlight. During transportation, they must be protected from shock, drops, and damage. Only by strictly controlling every step can we ensure optimal performance and extend the service life of the cable.
