Tilt Up

Schaeffer Electric recently completed a project in St. Louis, MO for a manufacturing client.  The project included 15kV power distribution, high bay LED lighting, low voltage, fire alarm, office space power and lighting, and distribution for various manufacturing equipment.  A key aspect for the customer was to install complex manufacturing equipment utilizing underground conduit for all interconnect wiring.  Utilizing our design capabilities and total station, we were able to surpass the customer’s expectations and deliver a very clean installation.

Mechanical Dynamics & Analysis, Ltd. – St. Louis, MO

Work was recently completed on the first High-Speed Balance Facility in the St. Louis area, for power generating equipment, at Mechanical Dynamics & Analysis (MD&A). The facility was designed to be the one of the most modern balance facilities for power turbines in the United States with the ability to balance both steam and gas turbines as well as generator fields.  The project team was lead by Tarlton Corporation and included critical team members Corrigan Company for the mechanical work and Schaeffer Electric Company for the electrical work.  Key portions of work for Schaeffer included variable frequency drives and power for 8000 hp and 3000 hp motors, building addition, new Ameren 14 MVA substation, 15KV customer switchgear, (5) 15KV transformers, cooling tower, (3) UPS systems, extensive process control, vacuum penetrations, along with general lighting and power.  Schaeffer could not be more pleased with the team atmosphere throughout this project promoted by Tarlton and MD&A.  It took a strong collective effort to complete the project in the timeline required and it was exciting to be a part of that effort.
