YBT12-24 Series Combined Substation is researched and developed by our company in order to satisfy the need of city net construction. It has compact structure, strong whole set, safe and reliable operation, convenient maintenance, beautiful appearance. It is widely used in outdoor power supply fields such as high buildings, residential zone, station, wharf, port, park, marketplace and factory and mining, etc. The product can not only be used in a closing net for power distribution but also in radial grid for terminal power supply. The product has novel structure, reliable performance, excellent in quality and technical characteristic reachs to the national advanced level.

a. The frame of substation is made of channel steel and angle steel, it is tough enough mechanically and rigidly.
b. Materials of the enclosure can be cold rolled steel plate, stainless steel plate, aluminum alloy plate, composite color plate, or cement plate strength by glass fiber.
c. Steel plates are used to isolate each bay, and lighting device has provided in the substation.
d. The roof is double-decked structure, which can prevent the heat radiation from increasing indoor temperature and have good ventilation effect at the same time.
e. There's an automatic air exhausting device at the top of transformer room to control the temperature.
f. The enclosure can be painted in many colors to coordinate with ambient environment.
