Single-pole disconnect switch L 31/090323

4-polefor railway applicationsindoor

These Driescher indoor switching devices are specifically designed for railway applications. They are in compliance with the specifications according to EN 50152-2. The 1-pole switches can be used for a rated voltage range of 15 kV to 27.5 kV, depending on the respective design, and for a rated current range of 400 A to 4000 A. References: 25 kV Madrid-Sevilla; 27,5 kV HarbinDalian, China The equipment can be installed in places at an altitude of up to 1000 meters above sea level. At an altitude above 1000 meters the rated insulation level of the switchgear must be adjusted accordingly. The switchgears are designed for use under normal operating conditions in compliance with EN 62271-1. According to this specification the following limit values apply: Ambient temperature: Max. value : +40°C Max. value of 24-h average +35°C Min. value (corresponding to class - 40°C "Minus 40 outdoors”) Allgemein These Driescher indoor switches are specially designed for railway applications. They meet the specifications according to the EN 50152-2. The 1-pole switches are designed for a rated voltage range from 15 kV to 27.5 kV and a rated current range of 400 A to 4000 A. Fittings The switch disconnectors are basically fitted with a stored energy mechanism for rapid making and braking. The current carrying components are made of electrolytic copper with electro-silver plating in compliance with QTL 0200. All steel parts have been given an electro-plated coating which provides excellent corrosion resistance. Every switch is provided with an earthing screw
