As underground cabling and urbanization progress, constructing heavy concrete compact secondary substation (CSS) units in new remote locations becomes impractical. To address this issue, ABB has created a CSS enclosure solution that merges the benefits of steel and concrete. This solution is durable enough to shield the equipment from extreme temperatures and lightweight enough to be easily transported to remote areas.
This modular platform, named UniPack-G (with "G" signifying glass reinforced polyester, or GRP), can accommodate the CSS along with a variety of additional electrical equipment. The ABB UniPack-G boasts a scalable design that meets demanding application requirements, particularly in secluded locations where renewable energy is generated. It is suitable for diverse climates, from cold to hot, and can be installed in environments ranging from salt-spray-exposed coastlines to remote, heat-drenched sandy deserts.
Since a UniPack-G CSS enclosure is lighter than its concrete counterpart, it reduces transportation costs and simplifies installation. Its low-maintenance nature makes it perfect for isolated and hard-to-reach locations.
