Abstract: A transformer (1) is provided, which comprises a tank (10) having an enclosed volume (11) with an insulating material (13), the tank (10) comprising at least one channel (25) extending through the tank (10), wherein the interior of the at least one channel (25) is separated from the enclosed volume (11) of the tank (10) by a channel wall (17). A transformer core (30) is provided outside of the enclosed volume (11), comprising at least one core leg (32) extending through the tank (10) via the at least one channel (25). At least one coil (50, 52) is located inside the enclosed volume (11), the coil (50, 52) being wound about the at least one channel (25), wherein the tank (10) has an inner wall or outer wall (16) comprising a semiconductive layer (40), which comprises fibers (42) embedded in an impregnating material (44).
