Is the distribution box a transformer power supply

Is the distribution box a transformer power supply

An electrical transformer box is a protective, enclosed unit containing a distribution transformer, which steps down high-voltage electricity to lower, usable voltages for homes and businesses. A newly constructed residential area introduces a 10kV power line to a substation. From the transformer's low-voltage side (0. 4kV), power is distributed to a main distribution panel (primary distribution box). From there, it is routed to individual building distribution boxes (secondary. Electric power distribution is the final stage in the delivery of electricity. Electricity is carried from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 33 kV. Primary distribution systems consist of feeders that deliver power from distribution substations to distribution transformers. Many feeders leave substation in a concrete ducts and are routed to a nearby pole.
