Abstract
A bullet resistant shield for electric power equipment constructed from standardized modular sections configured for easy erection in the field into walls and enclosures. The modular sections may be constructed at a factory and transported to the desired location where the sections are assembled together into walls and enclosures. The modules are sized for transportation by trucks over public roadway, rail, barge and so forth. Concrete foundations may be installed prior to arrival of the modular sections to ready the site for erection of the shied structure upon arrival of the modular sections. Unlike conventional bullet resistant enclosures, these sections provide adequate ventilation to avoid overheating of air-cooled electric power equipment, such as large substation transformers. One or more electric fans may be mounted in the section to provide forced air ventilation. The wall may be positioned to allow walk-up maintenance access without the use of doors.
