technical field

The utility model relates to a compact composite conductor overhead composite cable, which belongs to the technical field of power cables.

Background technique

With the continuous development of urban construction, the needs of various cables and wires required by people's lives are becoming more and more perfect. However, many cables and their ancillary facilities perform their own duties, so that cables for different purposes will be prepared separately. Pipelines and lines finally lead to criss-crossing and disorder of lines, which leads to continuous occurrence of safety accidents. Combining cables for different purposes and optimizing the structure of the cable itself can not only greatly reduce the space used for cables, but also greatly reduce the cost of using cables, which will become a new trend for civilian cables in the future.
