[0026] This embodiment provides an enhanced modular busbar frame, referring to... Figure 1 and Figure 2 It includes fastening studs 41, busbar frame clamps 1, fastening screw sleeves 4, and busbar pads 2. The busbar 5 is fixed by assembling the busbar frame and fixed to the cable tray, forming insulation with the cable tray to withstand the reaction force and dynamic stress generated by the rated short-circuit current supporting the busbar 5.

[0027] Reference Figure 3 The busbar frame clamp 1 has a straight rod structure and a defined length direction (refer to...). Figure 2 In the middle (a direction), the busbar frame clamp 1 has multiple mounting slots 11 with open openings. The mounting slots 11 are used to install busbar pads 2. The multiple mounting slots 11 are arranged sequentially along the length direction of the busbar frame clamp 1, and the openings of the multiple mounting slots 11 are set in the same direction, so that multiple busbar pads 2 can be installed on one busbar frame clamp 1.

[0028] The mounting groove 11 has a U-shaped structure, and the mounting groove 11 is in the first direction (refer to...). Figure 2 An opening is formed on one side of the busbar frame clamp 1 in the middle (b direction), and in the second direction (refer to...) Figure 2 The first direction and the second direction are perpendicular to the length direction of the busbar frame clamp 1 in the middle (c direction). Preferably, the first direction and the second direction are perpendicular to the length direction of the busbar frame clamp 1.
