PSP */10/III surge arresters are designed to protect traction substations and associated DC traction networks from atmospheric and switching overvoltages. They are used to protect traction networks, electrical equipment of trolleybuses, trams, and electric locomotives. They require no maintenance during operation. The PSP */10/III series is designed for outdoor and indoor applications. The functional part of the arresters is a column of varistors sized for the continuous operating voltage Uc. The housing material demonstrates high resistance to the effects of surface currents generated by charge flow or electric arcs. It has hydrophobic properties and demonstrates excellent resistance to atmospheric influences, pollution, and UV radiation. Cover lids, connection screws, nuts, and terminals are made of stainless steel. The design and technical parameters of the PSP series surge arresters comply with ČSN EN 60099-4 ed. 3: 2018, IEC 60099‑4: 2014 and ČSN EN 50526‑1: 2012, EN 50526‑1: 2012.
