ARPK — Prefabricated Concrete Substation

The ARPK series comprises MV/LV substations built from precast reinforced-concrete panels for projects requiring large rooms for several switchgear sections, multiple transformers and LV boards. Panels are factory-made and rapidly assembled on site.

Typical configurations: width from 6.6 to 26.6 m in 2 m steps, depth 3.8 or 5 m, height 3.8 m (three arrangements, Annex 1–3). The room layout — switchgear hall, transformer bays, LV room, battery room — is defined by the project.
