Compact and customised package substations

E+I Engineering’s package substations consist of an approved choice of transformer, MV circuit breaker and LV switchboard house as one complete assembly. E+I Engineering can offer double ended package substations for use in more complex schemes. Package substations offer flexibility and cost savings by optimising available space and removing the need for additional switchgear rooms.
