Medium voltage productsUniGear ZS2
Medium voltage switchgear for primary distribution for 36 kV
From power stations down to distribution substations, ABB provides a reliable, high quality solutions for products, systems and services. As a single source partner, ABB is the world’s largest and most complete supplier of switchgear and systems for electric power transmission and distribution applications.
UniGear ZS2 is medium voltage metal-clad switchgear with a metal enclosure, suitable for indoor installations. Metal partitions segregate the compartments from each other and the live parts are airinsulated. The switchgear is modular and this provides a coordinated approach that enables the ideal solution for each installation to be built up by placing standardized units side by side. The switchgear is simple to configure and selection of the correct apparatus and instruments for specific applications does not require dedicated solutions.
