It comprises at least a rigid linking rod (3) directly linking the rigid end bars (1 and 2) provided with clamps.

is installed between 2 floors of equal heights or for covering an extra expansion joint.

The core has a high density and allows installation of up to 400 m² (20 x 20 m) without transition profile.

The busway joint parameter sensor (122) is disposed so as to sense a selected parameter of the busway joint (14).

A junction box incorporating an integrally formed shunt busbar.

Furthermore, the joint portion between the horizontal bar and the vertical bar may be more firmly reinforced by a reinforcing plate.

The electrode terminal (5) and the busbar electrode (2) are electrically joined.

The transmission circuit (140) is in data communication with the busway joint parameter sensor (122) and is configured to transmit real time busway joint parameter data.

When the transition region (9) of the bar element (36) engages the junction element (37), of which there is at least one, centric force transmission takes place between the bar element (36) and the junction element (37).

The press assemblies are configured to embed the connection plates into the truss members.

The posts (14, 15) which define the goal comprise individual uprights with no connecting cross-bar and no net.

Also, the junction box (15) and the inverter (13) are connected by a bus bar (16).

The bar (22) is rotatably arranged to the foot support (4) in said joint (20).

One of the joining surfaces where the electrode terminal and the busbar electrode are facing is curved in a convex manner towards the joining surface.

A busbar power distribution device (10) comprises two busbar ducts (11, 12), junction means (20) for connecting the conductors of the two busbar ducts (11, 12).
