About Brunstock Electric
Brunstock Electric is a global technology brand for environmentally friendly electrical power systems. The portfolio includes battery energy storage systems (BESS), SF6-free medium-voltage switchgear (RMU), SF6-free primary GIS switchgear, power transformers with ester oil, compact substations (kiosk substations), step-up stations and transformer skids. The systems are packaged in steel enclosures (metalclad) as integrated solutions and are built and tested by manufacturing partners to specification; local representatives handle installation and commissioning. Fields of application include renewable energies, power transmission and distribution, industry, mining, utilities and infrastructure. Markets in Africa, Australia and Europe are served via representative offices in Australia, Germany, South Africa and Switzerland.
