Secondary unit substations | Secondary 1000 V and below
Eaton’s secondary unit substation is a close-coupled assembly consisting of primary high voltage equipment, three-phase power transformers and secondary low voltage equipment. Because the integrated transformer solution locates transformers and secondary distribution equipment near the load concentration, secondary distribution cables/buses are kept to minimum lengths —reducing power losses and exposure to faults, and improving voltage regulation and service continuity.
Standardization through IEEE results in proven unit substation designs with complete accessories and features.
Highest short-circuit strength
Highly researched and thoroughly tested unit substation designs withstand repeated large short-circuit currents in modern systems.
Easier handling and reduced maintenance
The secondary unit substation’s compact design reduces rigging and hauling costs and requires less installation space, while simplified accessories reduce maintenance costs.
Plug-and-play wiring reduces installation time and complexity
A secondary unit substation offers dedicated pull-apart terminal blocks and pre-made harnesses eliminate the headaches associated with wiring control and communications devices inside a substation.
