We proudly serve utility companies, electric cooperatives, and municipalities.
Sentry Electrical Group offers complete design build services for your substation project. Our team members work closely with the interconnecting utility to fully understand the requirements for physical interconnection, relay and protection, and communications.
Project managers spend initial time up front to better understand the customers needs and safety considerations to ensure the adequate level of design and redundancy is included in the overall design. Our procurement department performs a manufacturing review of the design as it is developed so that steel and equipment are optimally manufactured.
During and After Construction
During construction, our safety advisors and site inspectors complete multiple safety and quality assurance checks to help the construction flow smoothly and to make sure the substation will successfully perform as designed throughout its expected useful life.
Once construction is complete, each piece of equipment is field tested and checked to make sure all connections are properly installed and the equipment is safely and properly functioning.
The collaboration of engineering, construction and material suppliers provides our customers with the safest, most efficient, and cost effective substations.
