The 110 kV TT Chotoviny traction substation is used to power the traction line of the adjacent single electrified track Tábor – Benešov. In the framework of the modernization, the original equipment was replaced by a compact modular field air-conditioned traction substation (under the trade name CAIS – Compact Air-Insulated Switchgear), i.e. with devices on one steel structure. In terms of material costs, safety and reliability, CAIS is comparable to conventional air-insulated traction substation (AIS) but it brings significant benefits to other parameters such as built-up area and enclosed space, installation and maintenance time.
