Railway applications - Fixed installations - High-voltage/low-voltage prefabricated substations in AC and DC electric traction systems

SIST-TS CLC/TS 50711:2026

This document specifies - the service conditions; - rated characteristics; - general structural requirements; and - test methods of prefabricated traction substations for use in AC and DC electric traction systems, which as a minimum contain an enclosure and a traction switchgear designed and manufactured according to - EN 50123 6 in DC electric traction systems; - CLC/TS 50152 4 in AC electric traction systems. Traction substations using non-type tested traction switchgear are covered by EN IEC 61936 1:2021. NOTE 1 Due to the type testing requirements on the prefabricated traction substations only type tested traction switchgear is considered. The enclosures of the prefabricated traction substations for use in AC and DC electric traction systems are - designed for outdoor installation at locations with or without public accessibility; - connected by insulated cable; - operated from inside (walk-in type) or outside (non-walk-in type). NOTE 2 Prefabricated traction substations for railway applications are typically of the walk-in type due to the rating and resulting dimensions of the AC or DC traction switchgear. Prefabricated traction substations can be situated at ground level or partially or completely below ground level. In general a prefabricated traction substation comprises an enclosure, a traction switchgear and can include the following additional main components: - power transformers; - electronic power converters; - high-voltage and/or low-voltage switchgear and controlgear; - high-voltage and/or low-voltage interconnections; - auxiliary equipment and circuits. However, relevant provisions of this document are applicable to designs where not all these main components exist. NOTE 3 The term "main component”"is defined in 3.3.103 of EN IEC 62271 202:2022. NOTE 4 For example, a switching station in an AC electric traction system consisting of an AC metal-enclosed traction switchgear and auxiliary circuits only. NOTE 5 EN IEC 61936 1:2021 provides general rules for the design and erection of high-voltage power installations. As well, it specifies additional requirements for the external connections, erection and operation at the place of installation of high-voltage prefabricated traction substations compliant with EN IEC 62271 202:2022, which are regarded as a main component of such installation. Non-prefabricated traction substations, are generally covered by EN IEC 61936 1:2021. This document covers designs using natural ventilation and/or any other kind of cooling system. Due to the large number of different main components being addressed in this document the expression "main components shall comply with (the applicable subclause of) their specific product standard" is used in this document. This means that reference is to - EN 50123 6:2003 for DC traction switchgear; - to other parts of the EN 50123 series for switching devices also measurement, control and protection devices for DC traction applications; - CLC/TS 50152 4:2021 for AC traction switchgear; - other parts of the EN 50152 series for switching devices and also measurement, control and protection devices for AC traction applications; - EN 50328:2003 for electronic power converters; - EN 50329:2003 for traction power transformers; - EN IEC 61439-1:2021 for low-voltage non-traction switchgear; and - EN IEC 62271 200:2021 for high-voltage non-traction switchgear.
