The image shows a metal door with a sign on it. The sign is rectangular in shape and has a white background with black text. On the left side of the door, there is a yellow triangular warning sign with a black lightning bolt symbol in the center. Below the warning sign, it reads "UMSPANNER 31 35/5KV 6.4MVA". On the right side, there are two smaller signs - one is a blue sticker with white text and the other is a white sticker with blue text. The door appears to be old and weathered, with peeling paint and rust visible on the metal.
