UniPack-G

Did you know…
… that ABB’s eco-friendly compact secondary substation UniPack-G is ideally suited for the harshest environments?
Did_you_know_microsite_v2_UniPack-G_20201215_AN3

Compact secondary substations (CSS) play a key role in the reliable distribution of electricity, sustaining balance across the electrical network. A secondary network is the part of an electric power distribution network carrying electricity to end customers. Within this secondary network, the CSS typically houses critical elements such as medium-voltage switchgear and low-voltage switchboards as well as transformers and protection devices.

As underground cabling and urbanization continues, new remote locations are not ideal to build heavy concrete 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, while being lightweight enough to be easily transported, even to remote locations.

This new modular platform is called UniPack-G, where “G” stands for glass reinforced polyester (GRP). GRP is a material used in many everyday applications, such as wind turbine blades, boats, cable pillars and garden furniture. The platform can house the CSS along with a wide range of additional electrical equipment.

The ABB UniPack-G features a modular 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 much 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.

An award-winning ABB UniPack-G project is in the Swiss Alps on the artificial Lac des Toules, on one of the world’s largest floating solar farms, where the UniPack-G CSS operates at 1,810 meters above sea level. 

Key Facts:

  • Superior thermal insulation and rust-resistant design withstands harshest environments
  • Up to 20% more durable and 4 times lighter than a concrete equivalent
  • Highest level of arc safety ideal for public installation
