Direct burial cable is a type of cable laying method in which the cable is directly laid underground and covered with a protective layer. Its advantages mainly include the following:
Space saving: Buried cables do not require additional structures such as cable trenches or cable trays, making full use of underground space and saving the use of ground space.
Convenient maintenance: Since the direct buried cable is located underground and is less affected by external interference, its maintenance workload and maintenance costs are lower compared to other installation methods such as overhead cables.
High aesthetic value: Directly buried cables do not occupy ground space and do not affect urban landscapes and aesthetic value.
High safety performance: Compared to other laying methods such as overhead cables, direct-buried cables are less affected by external factors such as weather and human damage, thus having higher safety performance.
It should be noted that the disadvantage of directly buried cables is that the impact of the underground environment on the cables needs to be considered, such as soil moisture, groundwater level, underground pipelines, etc. Therefore, special attention needs to be paid during design and construction. At the same time, the difficulty of troubleshooting and repairing is relatively high when the cable fails.
In summary, direct-buried cables have the advantages of space saving, convenient maintenance, high aesthetic quality, and high safety performance, and are suitable for applications where there is sufficient underground space and high requirements for cable appearance and safety performance.
