[0064] FIG. 2 shows a cross-section view of an alternative application of the busbar structure (A) with metal body, which is the subject of the invention, providing protection against combustion.

[0065] The busbar structure (A) according to invention, consists main parts of pre-insulated conductors (6) providing energy transmission, the upper metal barrier (1), which is formed on the upper side of the said conductors (6) and increases the resistance of the said busbar structure (A) against external impacts, the lower metal barrier (2), which is formed on the underside of the said conductors (6) and increases the resistance of the said busbar structure (A) against external impacts, the left metal barrier (3), which is formed on the left side of the said conductors (6) and increases the resistance of the said busbar structure (A) against external impacts, the right metal barrier (4), which is formed on the right side of the said conductors (6) and increases the resistance of the said busbar structure (A) against external impacts, petroleum-derived in-frame resin (5) which is filled to the inner part of the frame on the side of the conductors (6), formed by the combination of the said upper metal barrier (1), the lower metal barrier (2), the left metal barrier (3) and the right metal barrier (4) in a rectangular form, on the side of the conductors, in such a way that there is no air gap between them, which are in adhesive contact with the inner sides of the upper metal barrier (1), the lower metal barrier (2), the left metal barrier (3) and the right metal barrier (4) and in case of overheating of said conductors (6), non-combustible petroleum-derived in-frame resin (5) because it does not contain oxygen, which carries out the combustion process, due to zero air gap, individual resin around conductor (7) formed to ensure that the conductors (6) are double insulated and cooling channels (8) formed on said upper metal barrier (1), lower metal barrier (2), left metal barrier (3) and right metal barrier (4) in order to ensure faster cooling of said busbar structure (A).

[0066] In order to prevent the combustion problem of the mentioned busbar configuration (A), the internal petroleum-derived in-frame resin (5) must be completely cut off from oxygen, and at the same time, the busbar configuration (A) must not exceed the temperature limits specified in the standards during normal operation.

[0067] In the studies carried out for this purpose, the entire perimeter of the petroleum-derived in-frame resin (5) surrounding the outer body of the conductors (6) was covered with a rectangular frame formed by combining the upper metal barrier (1), the lower metal barrier (2), the left metal barrier (3) and the right metal barrier (4) of sufficient thickness to have zero air gap.

[0068] The connection between the petroleum-derived in-frame resin (5) material in the interior and the oxygen in the exterior is reduced to zero. Likewise, the application is made in a way that there is zero air gap in the interior.

[0069] In the studies carried out, it has been observed that the internal heat of the busbar during normal operation is discharged better thanks to this method, and at the same time, since the connection of the resin material with oxygen to zero, the formation of combustion is prevented and the progression of the combustion is stopped.

[0070] On the other hand, thanks to the upper metal barrier (1), the lower metal barrier (2), the left metal barrier (3) and the right metal barrier (4), the amount of petroleum-derived insulating material used in the interior is reduced, as the resistance against external impacts increases. This further improves cooling.

[0071] In addition, in an alternative embodiment of the invention, cooling channels (8) are formed on the upper metal barrier (1), the lower metal barrier (2), the left metal barrier (3) and the right metal barrier (4), allowing it to cool much more quickly.

[0072] In the preferred embodiment of the invention, in-frame resin (5) and the resin around conductor (7) material are composed of cast resin material called Cast Resin, epoxy hardener and silica sand.
