The elementary purpose of RST type switchgears is to equip pole transformer stations with transformers up to 630 kVA with the function to supply rural, urban and industrial service customers. The switchgear enables energy distribution to objects using an overhead or cable nN network. Switchgears of EMITER production are used successfully and find their place in all distribution and industrial companies.
