Electric substation, also called box-type substation, is mainly cooled by natural air circulation.  Therefore, there should be no illegal pile around it, especially the transformer room door should not be blocked, but also should often remove the attachment on the shutter vent hole, to ensure that all electrical equipment does not exceed the allowable temperature.

The floor of box substation should be placed in a higher place, not in a low-lying place, so as not to affect the operation of equipment by pouring rain into the box.
