Substation Framework Structure

Qingdao Anbang New Energy's Substation Framework Structure is the company's independently developed and manufactured core load-bearing and support facility for substations, based on the needs of China's power construction and leveraging the production and processing advantages of its own factory.

It includes three main categories: reinforced concrete framework, steel structure framework, and prefabricated hybrid framework.

The substation framework strictly follows the "Intelligent Substation Design Code" and the "Seismic Design Code for Power Facilities," using high-quality Q235B and Q345B steel and C30-C50 high-strength concrete, precisely processed and rigorously tested.

It possesses core advantages such as stable structure, strong load-bearing capacity, wind and earthquake resistance, corrosion resistance, and broad adaptability.

As the "skeleton" of the substation, the framework is mainly used in key areas such as the main control communication building, power distribution device building, equipment supports, and structural supports, performing critical functions in electrical equipment installation, line laying, and load transmission.

It can be adapted to substations of different voltage levels, including 110kV, 220kV, and 330kV, supports customized design, and can meet various complex site requirements such as plains, hills, and coastal areas, as well as green and intelligent construction needs.

This provides reliable structural assurance for the safe, efficient, and long-term stable operation of substations, supporting the secure transmission of electrical resources.
