Transformers can be directly thrown into the transformer room using a car crane, or temporary tracks can be set up with wooden tracks. Three steps and lifting chains can be used to lift the transformers onto the temporary tracks, and then the lifting chains can be used to pull them into a suitable position indoors. Transformers should pay attention to their orientation and distance from the wall, which should be consistent with the drawings. The allowable error is ± 25mm. If there are no markings on the drawings, the horizontal distance from the wall should not be less than 800mm, and the distance from the door should not be less than 1000mm. Installation of transformer stand: Install transformer on double pole with a root gap of 2m between the two poles. Buried at a depth of 2m. The distribution transformer stand is fixed to two poles with two or four channel steels, and the height of the stand from the ground is not less than 2.5m. The plane slope of the stand is not more than 1/100. The waist railing should be wrapped with iron wire with a diameter of no less than 4mm for more than two turns, and the winding should be firm. The distance between the waist railing and the live part should not be less than 0.2m. At the same time, dust covers are installed on the high-voltage column heads of the transformer, and warning signs are hung on the transformer.
