Novel main transformer framework steel tube beam of 220kV outdoor transformer substation

The utility model discloses a novel main transformer framework steel tube beam of a 220kV outdoor transformer substation, which comprises a steel tube beam and a support. Two sides of the steel tube beam are respectively provided with a platform for workers to move; baffle plates are arranged on the outer lateral surfaces of the platforms; and antiskid strips are arranged on the platforms. As the two sides of the steel tube beam are respectively provided with the platform for workers to move, the workers can move on the platforms when installing, examining, repairing and maintaining the steel tube beam, and operating efficiency and operating safety are improved.
