Compact Sub Station (CSS)

We, Expert Engineers, is proud to announce that we have been officially appointed as a Franchisee for the manufacture and sale of Compact Sub Stations (CSS) in Nqube design (Lauritz Knudsen).

Compact Substation will take up just around a quarter of the area required for an open installation. It can be mounted in the basement, the yard, or on the roof.

What makes compact substations an ideal choice over traditional substations is that they are a complete solution that can easily fit into any configuration based on the customer’s needs.

We deliver compact substation transformers to different electrical utilities and industrial & commercial sectors.
