With the emergence of modern engineering facilities and equipment, the power consumption of various industries is increased rapidly, particularly, the appearance of numerous high-rise buildings and large-scale factory workshops, the traditional cable serving as a power transmission wire cannot meet the requirement in a large-current transmission system, and the parallel connection of multiple cables brings great inconvenience to field installation construction connection. Particularly, in power generation enterprises, power transmission from a generator to a transformer section is realized, and a cable bus is not separated.

In an electric power system, a bus bar connects together various current-carrying branch circuits in a distribution device, and functions to collect, distribute, and transfer electric energy. The bus is roughly divided into the following three types according to appearance and structure:

hard bus bar: including rectangular bus bars, circular bus bars, tubular bus bars, etc.

Soft bus: comprises an aluminum stranded wire, a copper stranded wire, a steel-cored aluminum stranded wire, an expanded hollow conductor and the like.

And (3) sealing the bus: the system comprises a common box bus, a split phase bus and the like.

The problem of laying and supporting the bus-bar is accompanied by the heavy use of the bus-bar. After the power generation enterprises are mainly researched from a generator to a transformer section bus support, the fact that most of the power generation enterprises support the section bus is found, and the door-shaped steel frame is generally adopted for erection. After special research, the erection mode is considered to be troublesome in construction and too high in manufacturing cost, so that waste of too much steel is caused.

The utility model provides a cable generating line support device, includes vertical girder steel, the cross section of vertical girder steel is the I shape, the top of vertical girder steel is provided with a plurality of horizontal girder steels, horizontal girder steel is the channel-section steel structure, and a plurality of horizontal girder steels distribute in proper order along the axis of vertical girder steel, and the both ends of every horizontal girder steel all are provided with the bearing diagonal who is connected with vertical girder steel.

Preferably, the plurality of transverse steel beams are equidistantly distributed along the axis of the longitudinal steel beam.

Preferably, the inclined support is of an angle steel structure.

Preferably, the inclined supports are connected with the lower flanges of the longitudinal steel beams.

Preferably, the transverse steel beam and the longitudinal steel beam are perpendicular to each other.

Preferably, the two legs of the channel steel structure are horizontally arranged.

The utility model has the advantages that:

the utility model discloses a channel-section steel both ends adopt the angle steel to link to each other with vertical girder steel, come the diagonal bracing in the horizontal girder steel plane as the channel-section steel structure to form the space support system, increase the part and the overall stability of structure system.
