Description

Technical Field

[0001] This utility model relates to the field of cable splicing technology, and more specifically to a cable splicing device. Background Technology

[0002] In power systems, cable splicing devices are used to connect different sections of power cables. They provide a low-resistance, highly conductive connection path, ensuring smooth current transmission from the generator to the consumer. For example, in urban power grids, electricity generated by power plants is transmitted to various substations via high-voltage cables. Cable splicing devices ensure effective connections between these cables, enabling a continuous and stable supply of electricity to residents and businesses.

[0003] If the devices are not in close and stable contact during the docking process, the resistance at the cable interface will increase, generating more heat when current flows. In power transmission cable docking, overheating caused by increased interface resistance can accelerate the aging of the cable insulation and even cause short circuits, affecting the reliability and safety of power transmission. Furthermore, in different usage scenarios, such as with the addition or removal of equipment or changes in terrain, the height of the cable docking device may need to be adjusted to adapt to the new layout.

[0004] Therefore, in order to solve the above problems, this application provides a cable splicing device. Utility Model Content
