YBT12-24 Prefabricated Substation
The YBT12-24 prefabricated substation is a 24 kV substation product series independently designed by Tian’an to meet the needs of urban grid construction. It features a compact structure, high degree of system integration, safe and reliable operation, convenient maintenance, and an aesthetically pleasing appearance. It is widely used in high-rise buildings, residential communities, railway stations, docks, ports, parks, shopping malls, industrial and mining enterprises, and other settings. The equipment can be employed in ring-network distribution systems as well as serve as a radial-grid terminal power supply. With its innovative design, reliable performance, and superior quality, this product’s technical specifications are at the leading domestic level.
1. The substation framework is fabricated from galvanized channel steel and angle steel, providing adequate mechanical strength and rigidity.
2. The enclosure material shall be cold-rolled steel sheet, stainless steel sheet, aluminum alloy sheet, composite color-coated sheet, or glass-fiber-reinforced cement board.
3. Each room in the substation is separated from the others by steel partitions to form independent compartments, and each compartment is equipped with lighting fixtures.
4. The substation roof features a double-layer structure that effectively prevents thermal radiation from raising the indoor temperature while providing excellent ventilation.
5. An automatic ventilation system is installed on the roof of the transformer room to control the room temperature.
6. The main switchgear may be the HXGT6A-24 compact gas-insulated switchgear manufactured by Tianan, or alternatively ABB’s and Schneider Electric’s compact switchgear models SM6-24, RM6-24, SafeRing, and SafePlus.
7. The enclosure color is optional, allowing it to blend in with the surrounding environment.
