A busbar applied in electrical cabinet disclosing an electrical cabinet set containing main busbars and secondary busbars built in a closed tubular shape, assembled in the referred electrical cabinet, which also presents insulators and secondary insulators, protection system in the main busbar systems, extension set and finally derivation connectors.

A busbar is provided for attaching a conductor to a support structure. The busbar can include a base wall and first and second side walls extending away from the base wall. A first flap can extend at an angle from the first side wall towards the second side wall and a second flap can extend at an angle from the second side wall towards the first side wall.

A system for isolating a power conductor includes a power conductor that extends between first and second flanking support structures. First and second collars are connected respectively to the first and second flanking support structures. The first and second collars each at least partially surround the power conductor and including respective first and second open tracks that cooperate with each other to define a sheet-receiving slot. An electrically insulating/insulative sheet is located in the sheet-receiving slot and extends continuously between the first and second collars. The sheet is secured in covering relation with the power conductor.

An electrical bus bar assembly configured to maintain spacing between run-over bus bars and horizontal bus bars. The electrical bus bar assembly having a first run-over bus bar and a second run-over bus bar spaced from the first run-over bus bar, and a first horizontal bus bar spaced from the first run-over bus bar. A yoke brace apparatus is coupled between and maintains a first spacing distance D1 between the first run-over bus bar and the second run-over bus bar, and one or more bus bar brace apparatus are provided to maintain a second spacing distance D2 between the first run-over bus bar and the first horizontal bus bar. Yoke brace apparatus and bus bar brace assemblies, bus bar assemblies including the yoke brace apparatus and/or bus bar brace apparatus, bus bar support assemblies, supported electrical bus bar assemblies, and methods of supporting electrical bus bars are disclosed, as are other aspects.

A neutral busbar stand assembly is provided which includes a pair of connectors fixing a position of at least one neutral busbar. Each of the pair of connectors including a top portion having a first and second connection end tabs, the first and second connection end tabs being secured in a bore of a neutral bar by a wire binding screw, and at least one downwardly extending leg from the top portion of the connector; and a base joining the pair of connectors via the downwardly extending legs, wherein a neutral busbar is mounted on the base and adjacent the downwardly extending legs of each of the pair of connectors.

A busbar assembly includes first, second, and third busbars at least partly arranged in parallel relation, wherein the first and second busbars are offset to each other such that a first straight line which does not pass through the second busbar is formed perpendicularly to a longer extension of the first busbar, the first and third busbars are offset to each other such that a second straight line which does not pass through the third busbar is formed perpendicularly to the longer extension of the first busbar, and the second and third busbars are not offset to each other such that a third straight line which is formed perpendicularly to the longer extension of the second busbar passes through the third busbar. The busbar assembly is configured at least partly mirror-symmetrical to a plane running through the first busbar and parallel to the longer extension of the first busbar.

A busbar is provided for attaching a conductor to a support structure. The busbar can include a base wall and first and second side walls extending away from the base wall. A first flap can extend at an angle from the first side wall towards the second side wall and a second flap can extend at an angle from the second side wall towards the first side wall.

A system for isolating a power conductor includes a power conductor that extends between first and second flanking support structures. First and second collars are connected respectively to the first and second flanking support structures. The first and second collars each at least partially surround the power conductor and including respective first and second open tracks that cooperate with each other to define a sheet-receiving slot. An electrically insulating/insulative sheet is located in the sheet-receiving slot and extends continuously between the first and second collars. The sheet is secured in covering relation with the power conductor.

A power distribution system includes a first bus including a first bus bar and a second bus bar. A first portion of the first bus is located in a position where the first bus bar and the second bus bar extend parallel to each other. A space is located between the first bus bar and the second bus bar in the first portion of the first bus. A run-over bus includes two or more run-over bus bars, wherein at least a cross-sectional portion of at least one of the run-over bus bars is located in the space and the at least one run-over bus bar extends parallel to the first bus bar and the second bus bar. Other systems and methods are disclosed.

A busbar system includes a plurality of bar modules arranged one behind the other and connected to each other via clamping brackets. Each bar module has a plurality of busbars. The bar module end including the recesses running in a longitudinal extension is inserted into the clamping bracket and the bar module end with the recesses running transversely to the longitudinal extension is suspended on the opposite side in the clamping bracket. Each of the busbars of the one bar module rests laterally against a busbar of the other bar module and the recesses, as viewed from the side, form a through-opening, through which a tensioning element supported on the clamping bracket runs, which presses together the sides of the busbars which rest against each other.
