A plurality of end supports 300 are symmetrically distributed across the composite beam assembly 100 so as to correspondingly support the symmetrically distributed line composite insulators 102 while providing a symmetrical structure to the composite beam assembly 100. In other embodiments, the beam assembly may have an asymmetric structure if desired, and the end supports may be distributed asymmetrically on the beam assembly, for practical purposes, and are not limited herein.
Preferably, the axes of the two line composite insulators 102 and the axis of the post composite insulator 101 are located on the same vertical plane, so that the stress between the two lines is in the same direction, the internal acting force caused by the different stress directions of the two lines is avoided, and the bearing capacity of the structure can be fully utilized.
Further, referring to fig. 1 and 2, in order to hook a wire, the power transformation framework 1000 further includes two second wire hanging plates 112, the two second wire hanging plates 112 are respectively disposed at the connection positions of the post composite insulator 101 and the two flange assemblies 400, and are clamped between the flange 1011 at the end of the post composite insulator 101 and the flange assemblies 400, the second wire hanging plates 112 are provided with a plurality of wire hanging holes 1110, and the wire hanging holes 1110 are used for hanging a wire. Because the post composite insulator 101 and the first supporting portion 211 are both made of composite insulating materials and have good insulating performance, the wires can be directly hung on the first wire hanging plate 112 through wire hanging hardware fittings.
The support assemblies 200 are arranged at intervals along the first direction, each support assembly 200 comprises two support columns 210, each support column 210 comprises a first support part 211 and a second support part 212, and the first support part 211 is made of a composite insulating material.

Further, in the two support assemblies 200 fixedly connected to the ends of the composite cross beam assembly 100, one support assembly 200 further includes an auxiliary support column 220, the auxiliary support column 220 includes an insulating section 221 and a metal section 222, the insulating section 221 and the metal section 222 are fixedly connected to each other, and the insulating section 221 and the first support portion 211 are connected to each other through a flange assembly 400. The insulating section 221 is a composite insulating material. The auxiliary support posts 220 are located out of the plane of the two support posts 210 to limit displacement of the composite power transformation frame 1000 in the first direction. The auxiliary supporting columns 220 are provided with crawling ladders, so that the requirement that people must be arranged in the power transformation framework specification is met.

Since the power transformation frame 1000 mainly receives a horizontal tension in addition to the gravity of the wire, the line composite insulator 102 may be provided in the horizontal direction in order to enhance the horizontal tension capability of the power transformation frame 1000. Specifically, in one embodiment, as shown in fig. 3, composite beam assembly 100 includes one post composite insulator 101 and four line composite insulators 102. Specifically, the plane where the axis of the post composite insulator 101 and the center line of the support assembly 200 are located divides the space into a first side and a second side, and the first side and the second side are both provided with two line composite insulators 102.

Specifically, end support 300 is disposed perpendicular to post composite insulator 101, and the axis of end support 300 is located in the same horizontal plane as the axis of line composite insulator 102 and the axis of post composite insulator 101.
Although the force borne by the power transformation framework 1000 is mainly in the horizontal direction, the self weight of the composite beam assembly 100 and the weight of the hardware and the wires hooked on the composite beam assembly 100 still need to be borne in the vertical direction, and these vertical forces can cause the composite beam assembly 100 to sag downward. When the sag is large, the ground distance of a lead hooked on the composite beam assembly 100 is possibly smaller than the standard safety distance, so that the vertical sag is eliminated in order to ensure the safety of a hanging wire, the composite beam assembly 100 can be set to be a pre-arch structure, namely, the two ends of the composite beam assembly 100 are low, the middle of the composite beam assembly is high, and the sag generated due to stress is offset in the original structural design.
To further improve the load carrying capacity of the power transformation framework 1000, in an embodiment, referring to fig. 4, the composite beam assembly 100 includes six line composite insulators 102 and two post composite insulators 101, and the two post composite insulators 101 are connected to each other to form an insulating beam 110.

Preferably, line composite insulator 102 is fixedly attached to the middle of insulating cross member 110, i.e. line composite insulator 102 is fixedly attached to the joint where two post composite insulators 101 are connected to each other. Specifically, both ends of the line composite insulator 102 are provided with end fittings, the end flange 1011 is provided with a hanging piece, and the line composite insulator 102 is fixedly connected to the hanging piece of the end flange 1011 through the end fittings. The line composite insulator 102 is fixedly connected to the middle of the insulating beam 110, which is beneficial to increasing the moment of the line composite insulator 102 and fully utilizing the tensile capacity of the line composite insulator 102.
The axes of the four line composite insulators 102 and the axis of the post composite insulator 101 are located in the same horizontal plane and used for providing horizontal tension; the axes of the other two line composite insulators 102 and the axis of the post composite insulator 101 are located in the same vertical plane. The two line composite insulators 102 are arranged in the vertical direction, so that pulling force can be provided in the vertical direction, the force generated in the vertical direction by the self weight of the insulating cross beam 110 and the gravity of the wire can be overcome to a certain extent, and the vertical sag of the insulating cross beam 110 is eliminated. Certainly, in other embodiments, the center lines of the four line composite insulators and the center lines of the two insulating cross beams can also be located on the same curved surface, and by the arrangement, the overall stress of the cross beam assembly can be optimized, so that the structure is more stable.

Specifically, the wire hanging point may be directly disposed on the composite post insulator, or the hanging point may be disposed on a connection node between the composite post insulators, which is selected according to actual situations, and is not limited herein.
In summary, the composite cross beam assembly is added with the line composite insulator to improve the overall bearing capacity of the composite cross beam assembly, and the line composite insulator is arranged in the incoming and outgoing line direction (perpendicular to the first direction and perpendicular to the plane of each support column) to share the horizontal stress of the support column composite insulator; by arranging the line composite insulator in the vertical direction, the longitudinal stress of the post composite insulator can be reduced to a certain extent, and the sag is eliminated; the tensile property of the line composite insulator and the compression resistance of the post composite insulator are fully utilized, the mechanical strength of the composite beam assembly is guaranteed under the condition that the large-size post composite insulator is not needed, the production cost can be further controlled, and the economical efficiency of the composite power transformation framework is improved.
