Custom Engineered Controls Details

Whether it’s a utility substation or an industrial petrochemical plant, Phoenix Electric understands that each customer has their own specific needs when it comes to controlling high voltage equipment. That’s why we combine our knowledge of switchgear and circuit breaker controls with an understanding of each end user specification. The result is a control package custom designed to meet the needs of each application. Combined with American engineering and craftsmanship, our controls are unmatched in performance and reliability.

Local control cabinets (LCC’s) are used to control gas insulated switchgear and interface with substation protection panels.
