[0002] A prefabricated substation transformer is a factory prefabricated indoor and outdoor compact power distribution equipment integrating high-voltage switchgear, distribution transformers and low-voltage distribution devices. It organically combines functions such as transformer step-down and low-voltage power distribution, and is installed in a moisture-proof, dust-proof, mouse-proof, fire-proof, anti-theft, heat-insulating and fully enclosed steel structure box. The selection and installation of transformer cables are an important part of the power system, which is related to the safe operation of the transformer and the stability of the entire power system.

[0003] A lapping mechanism for a power cable with the publication number CN 218335289 U is used to lap the connection head of the cable.
