A Transformer Cubicle is a prefabricated, protective enclosure that houses electrical transformers, along with associated control and protection equipment. These cubicles are designed to provide a safe and controlled environment for electrical transformers, ensuring they operate efficiently while minimizing the risk of hazards, such as electrical faults, fire, or overheating.

Transformer cubicles are typically found in industrial, commercial, and power generation settings, where transformers play a critical role in voltage conversion and power distribution.
