Various Railway companies within the UK and Europe have approved TENMAT L21, L23 and L26 materials for fabricated arc chutes for both trackside and rolling stock.
TENMAT arc chute materials are working in applications up to 11,000 V / 2,000 A AC and 3,000 V / 1,000 A DC. One particular GEC designed arc chute utilises L21 and ARCLEX and is used on the Type 319 Thames Link EMU which is designed to work at 750 V DC (30,000 A breaking load) or 25,000 V AC.
Network Rail have approved L21 for several types of arc chutes used in the power switchgear at track side substations, which provide power for mainline train services in the South East of England. Other arc chutes are also used by Metro & Tramway authorities, SNCF France uses L26 for arc chutes constructed to specification St 273 Cat 1.
In Norway, ARCLEX is used by Oslo Tramways because of its high resistance to electric arcs and very low moisture absorption providing excellent electrical properties in humid atmospheres. It is also used on railway track side and signaling switchgear.
REFRAVER S is specified by some of the world's most prestigious companies, e.g. the French railways SNCF to St 273 Cat 2, Belgian railways, the underground systems in Paris, Milan and Chile. Major switchgear manufacturers use REFRAVER for arduous applications. Russian Railways have now approved REFRAVER for use in their high performance switches via a major European switch manufacturer.
