Technical Field
[0001] This utility model relates to the field of power cable technology, specifically to a power cable laying device. Background Technology
[0002] Power cables, also known as electrical cables, are devices for transmitting electrical energy or signals. They are typically composed of several or groups of conductors. The main types of wires and cables used in power systems include overhead bare wires, busbars, power cables (plastic cables, paper-insulated power cables (which have been largely replaced by plastic power cables), rubber-sheathed cables, and overhead insulated cables), branch cables (which replace some busbars), magnet wires, and electrical equipment wires and cables for power equipment.
[0003] When laying power cables, workers need to manually drag the cables to the laying position. The cables are usually wound on a spool. When the cables are pulled out, they will coil due to inertia, making it difficult to place them into the laying trench and reducing the laying efficiency. To address this, we propose a power cable laying device. Utility Model Content
