Compact Composite Substation Gantry
Fully composite substation gantry is completely composed of composite post insulators, and the composite hollow insulators with smaller width and lower height between layers are connected in series to form beams to realize the function of entering and exiting lines.
The traditional substation gantries adopt all-steel structures or cement-combined steel structures, and they have mechanical defects such as heavy weight, being prone to rust or cracking. There are also problems like wide gantry corridors, excessive height, large floor area, difficulties in transportation and installation. Moreover, faults and accidents such as jumper wind deviation discharge are likely to occur.
With the adoption of the Shemar composite gantry, conductors are directly connected to the composite crossbeams, eliminating the need for tension insulator strings and suspension insulator strings. The jumper wires are essentially removed, which not only prevents wind-induced displacement of jumpers but also reduces the overall structure height. And the Shemar composite gantry addresses the problems of explosion, flashover and brittle fracture. Furthermore, the application of Shemar composite external insulation enables maintenance-free operation throughout the entire life-cycle.
The composite substation gantry eliminates the electrical insulation distance required for the side-phase conductors to the support columns, thereby reducing the structure's floor area laterally.
The composite substation gantry reduces the height of suspension insulator strings, resulting in a significant decrease in overall dimensions.
The composite gantry significantly reduces steel consumption and eliminates the use of porcelain or glass insulators, resulting in lower initial costs compared to traditional steel gantry, while reducing the floor area by 15% at the same time.
