UniPack-G

Eco-friendly GRP compact secondary substation ideal for harsh environments

As underground cabling and urbanization continues, new remote locations are not ideal to build heavy concrete compact secondary substation (CSS) units. To meet this challenge ABB has developed a CSS enclosure solution that combines the benefits of steel and concrete, is robust enough to protect the equipment inside from the extremes of heat and cold, and is lightweight for ease of transport to remote locations.

This modular platform is called UniPack-G, where “G” stands for glass reinforced polyester (GRP), can house the CSS along with a wide range of additional electrical equipment.

The ABB UniPack-G features a scalable design that meets demanding application requirements, especially in secluded areas where renewable energy is being generated. It is appropriate for a variety of cold, moderate and hot climates at locations ranging from sea-spray soaked coastlines to remote heat-seared sandy deserts.

As a UniPack-G CSS enclosure weighs less than its concrete equivalent, transportation costs are minimized, and ease of installation is increased. It’s low-maintenance requirements make it ideal for isolated and difficult to access locations.
