This European Standard does
24、not fall under any Directive of the EC. In the relevant CENELEC countries these A-deviations are valid instead of the provisions of the European Standard until they have been removed. Clause Deviation 1.1 Italy (I.S.P.E.S.L. (*) Rules, 95 revision: VSR.8.B.1; VSR.8.B.2; M.15.D.2 to .4.) For high-vol
25、tage alternating current circuit-breakers containing gas-filled compartments, the design pressure is limited to a maximum of 0,5 bar (gauge) and the volume is limited to a maximum of 2 m3. Gas filled compartments having a design pressure exceeding 0,5 bar (gauge) or a volume exceeding 2 m3shall be d
26、esigned according to Italian pressure vessel code for electrical switchgear (DM 1 December 1980 and DM 10 September 1981 published on Gazzetta Ufficiale n 285 dated 16.10.1981). This requirement is not applicable for gas filled compartments having a design pressure exceeding 0,5 bar (gauge) but a vo
27、lume not exceeding 25 dm3. Italian laws apply to gas pressurized enclosures made of both insulating and metallic materials with a capacity of 25 liters or above, a design pressure higher than 0,05 kg/cm2and a temperature range: -25 C/+100 C (only for insulating materials). Moreover, the manufacturer
28、 of any electrical equipment, which comprehends gas-pressurized enclosures, must submit the design of the pressurized enclosures itself to a proper legal Authority indicating the stresses and the loads which have any influence on the design itself. For each of the stresses the manufacturer must indi
29、cate the design values and the relevant computations. Only the use of porcelain type A or S (Aluminous or Siliceous) is permitted.
