Electric installation of cable structure

The utility model relates to an electric installation of cable structure, including the basis, install the consumer on the basis, still include and erect main crane span structure aloft, branch's crane span structure is connected to position that the inside cable that has laid of main crane span structure, main crane span structure are close to the consumer, branch's crane span structure is the cell type, and accesss to the electric power kneck of consumer, the branch crane span structure moves towards along level and vertical direction, sets up obliquely slant wire casing in the corner position, the cable extends in the cell type of branch's crane span structure to the connection is at the electric power interface of consumer. This electric installation of cable structure need not bury the cable pipe in advance underground, sets up branch's crane span structure of cell type between main crane span structure and consumer, and during the groove of branch's crane span structure was packed into to the cable, it
