CE-BF Switchboards withdrawable for Arc Furnace ≤ 40,5kV CE-BF Switchboards with withdrawable circuit-braker up to 40,5kV they are designed for use in the meltshop industrial application for command and protection of Tranformers for Electrical Arc Furnace and Ladle Furnace. GENERAL CHARACTERISTICS In according to the international standards IEC 62271-200 the CE-BF switchboards are classified for “Loss of service continuity” LSC2B. The circuit-breaker has fixed on trolley with wheels for facilitate the extraction during the maintenance activity and assicurate an easily substitution. The connection of the circuit-breaker the bus bars is performed with a special floating contacts for absorb the mechanical vibration during the working cycle. VERSIONS These kind of switchboards can be designed in basic application with a single circuit-breaker or for special application where we are able to make engineering and supply to special customized versions with circuit breakers in parallel or in cold backup. Option Engineering and supply of the bus duct and devices for overvoltage protection of furnace transformer. Light or pressure device to limit internal arc fault duration. Other info ELECTRICAL DATA Rated voltage up to kV 40,5 Rated power frequency withstand voltage (1min.) up to kV 85 Rated lighting impulse withstand voltage up to kV 185 Rated frequency Hz 50/60 Rated short-time withstand current (3 sec.) up to kA 31,5 Peak current up to kA 80 Rated current up to A 3150 Rated current with two breakers in parallel up to A 5000 STANDARDS AND TESTS The CE-BF switchboards are complies with the main Italian and International standards, these have performed all relevant test carried out by qualified Laboratories. 12345 Headquarters and Factory: via G.
