If you are talking about the primary wires to the transformer then yes they have to be encased in concrete.

How do you encase steel beams in concrete?
When designing composite members, one first needs to consider the properties necessary of the beam, in response to the expected loading. Basically, what will the beam experience? Is it flexural loads, or compressive/axial forces? The loading will greatly influence how the steel moves with the concrete as they are bonded together, and whether or not some bonding grout or other bonding agents are needed. There are many ways you can encase a steel beam in concrete, but let's assume one case: you have a beam that will take mainly flexural loads and that you want the steel beam to be fully encased by the concrete (no steel showing on the outside, in other words). What I would do is install formwork to encase the conecrete on a suitable, hard surface. Then, after having selected the right steel section for the beam, I would drill small holes in the beam flanges in order to attack galvanized anchors/wires. These can be placed anywhere you like, as long as there are not too many of them. These anchors, typically two on each side of the beam's total length, could be attached to cables or chains that are, in turn, attached to hoists or engine-mounts that can lower the beam carefully into the desired position inside the concrete formwork. Make measurements for how low the steel beam should sit in the concrete, and doublecheck your measurements: after this, there's no turning back. Add concrete to the mix and, if you have concrete vibrators, use them to allow for proper concrete mix settlement and extraction of air bubbles from the mix. This will also ensure a good bond between the concrete and the steel. Then, let the concrete set for 5-7 days and store it in a humid room or location (humid, not wet/rainy). Lastly, remove formwork and cut the wires/anchors that are sticking out of the concrete. I would put some appropriate sealant on these locations, as they can be sites for water infiltration in the concrete. Their inner portions cannot be removed at this point. So there you have it, my approach to encasing steel beams in concrete.
What is Cast Resin Transformer?
Cast-resin power transformers encase the windings in epoxy resin. These transformers simplify installation since they are dry, without cooling oil, and so require no fire-proof vault for indoor installations. The epoxy protects the windings from dust and corrosive atmospheres. However, because the molds for casting the coils are only available in fixed sizes, the design of the transformers is less flexible, which may make them more costly if customized features (voltage, turns ratio, taps) are required.
Is a pencil an invention or an innovation?
It's debatable and depends on how you want to define invention and innovation. The first versions of pencils were just graphite sticks wrapped in something like string or sheepskin to facilitate stability while they were used (mostly for art purposes). The version we think of - two wooden halves glued together around a graphite core - was invented around 1560 so that innovation might be considered the invention of what we now know as the pencil. Obviously there have been many innovations and inventions related to pencils since then including the mechanical pencil and using plastic to encase the "lead" instead of wood.
Can schedule 40 PVC be used for natural gas?
The National Fuel Gas Code does permit its use for exterior, buried gas line only. None of th PVC can be above ground and must transition to black pipe before emerging above ground. The transition connection must be wrapped in plastic and taped with the appropriate pipe tape, or tarred. A trace wire must be buried in the trench above the gas line so that it can be located electronically and the pipe must be identified as gas. There is a yellow version of PVC specifically made for gas line use, but it is hard to find in some parts of the country. Otherwise you must bury the yellow caution tape for gas lines above it with the trace wire. This is the tape that looks like the yellow "Police Line Don't cross" tape but says "Caution gas" on it. It is not approved for above ground and inside a building by itself. There are ways to encase it to make it possible for interior use, but for the most part you are better off sticking with black pipe inside a house. As always your local building codes and jurisdiction may vary from this standard (not uncommon) so it is probably a good idea to check with your local code enforcement agency. Note: when outside black pipe must be insulated or painted to protect it from the weather THUS many codes do allow and encourage galvanized pipe when exposed out doors
