Description

Technical Field

[0001] This invention belongs to the field of power technology, and in particular relates to a power cable that can be flexibly assembled. Background Technology

[0002] In existing technologies, cables are usually laid after being formed. The power transmission units in cables are usually circular structures. This structure results in large gaps in the cable core space, causing a waste of space. This is especially true when laid in square or rectangular pipes, where space cannot be effectively utilized. As power transmission and communication densities increase, pipe rental fees become increasingly expensive.

[0003] In practical use, different users generally have different power capacity requirements. Therefore, when power supply companies activate services for users, they provide meters and wires according to the load requirements; that is, the effective cross-sectional area of ​​the power supply wires will be different. In existing technology, using the same specification cable for different users clearly increases the burden on power supply companies. On the other hand, using different specifications of transmission lines within the same cable in existing technology leads to wasted space and raw materials. For example, commonly used are round transmission lines and round outer sheaths. When multiple round transmission lines are placed within the same round outer sheath, if the diameters of the transmission lines are different, the space utilization rate within the outer sheath is very low. Using transmission lines of the same diameter results in material waste for users with different needs. Therefore, suppliers and the industry have a strong need for cables that can fully utilize space resources and allocate power to meet the needs of different users.

[0004] CN213521141U discloses a buried cable conduit assembly method, which consists of several sub-pipes. Each sub-pipe is a long strip pipe with a square cross-section. The four corner surfaces of each sub-pipe are designed as quarter-cylindrical surfaces extending radially along the sub-pipe. The radii of the quarter-cylindrical surfaces at the four corner surfaces are the same. Grooves of equal length are formed on the four sides of each end of the sub-pipe, distributed circumferentially along the sub-pipe. However, this method also fails to solve the aforementioned problems. Summary of the Invention
