36、section 3.14 steel ratio the ratio of steel area to aluminium area as a percentage in AxF/Syz conductors 4 Designation system A designation system is used to identify stranded conductors made of formed aluminium, with or without steel wires. Homogeneous aluminium conductors are designated AxF, where

37、 x identifies the type of aluminium. Composite aluminium conductors are designated AxF/Ay or AxF/AyF, where AxF identifies external wires (or the envelope) and Ay or AyF identifies internal wires (or the core). Composite aluminium-steel conductors are designated AxF/Syz or AxF/SA, where AxF identifi

38、es the external aluminium wires (envelope), and Syz or SA identifies the steel core. In the designation of zinc coated steel wires, y represents the type of steel (regular, high or extra high strength) and z represents the class of zinc coating (A or B). Conductors are identified as follows: a) a co

39、de number giving the equivalent conductive section of A1F aluminium expressed in mm 2 ; b) a code number giving the area of the core material in mm 2 , if used; Page6 EN62219:20026122 9 EI:C0022 7 c) a designation identifying the type of wires constituting the conductor. For composite conductors the

40、 first designation applies to the envelope and the second to the core; d) a number giving the nominal diameter of the conductor. EXAMPLE 1 500-A1F-262: conductor made of A1F formed aluminium wires. Its area is 500 mm 2and it is (262 0,1) mm in diameter. EXAMPLE 2 505/65-A1F/S1A-281: conductor made o

41、f A1F formed aluminium wires and S1A regular strength steel with class 1 zinc coating. The area of A1F aluminium is 505 mm 2 and the area of S1A steel is 65 mm 2 . The conductor nominal diameter is (281 0,1) mm.The following are examples of some possible conductor types. Conductors made of different

42、 combinations of wire types are also permitted. A1F, A2F, A3F A1F/S1A, A1F/S1B, A1F/S2A, A1F/S2B, A1F/S3A A1F/A1, A1F/A2, A1F/A3 A1F/SA, A2F/SA, A3F/SA 5 Requirements for stranded conductors 5.1 Material Stranded conductors shall be made up of formed aluminium wires and, when applicable, of round zi

43、nc-coated or aluminium clad steel wires or round aluminium wires. Before stranding, all wires shall have the properties specified in IEC 60104, IEC 60888, IEC 60889 or IEC 61232 as applicable (see note). Wires formed before stranding shall have properties calculated based on their equivalent round w

44、ire diameters. NOTE The resistivity of these metals is as follows (in increasing order): A1F: 28,264 n m (corresponding to 61 % IACS); A2F: 32,530 n m (corresponding to 53 % IACS); A3F: 32,840 n m (corresponding to 52,5 % IACS). 5.2 Formed wires Three production processes are recognized in this stan

45、dard. One uses wires which are shaped in one process and stranded in another. The second method both forms the wires and then strands the wires in a single operation. In the third method a layer of round wires is first stranded and then that layer is compacted to a circular cross-section. Additional

46、 layers of round wires may be stranded and compacted or additional layers of formed wires may be stranded over the compacted core. In any of these cases the materials shall comply with IEC 60889 or IEC 60104. In the first case, the tests shall be performed on the formed wires prior to stranding and

47、the properties shall be based on the equivalent wire diameters. In the other cases, the tests shall be performed on the round wires prior to forming and stranding and properties shall be based on the round wire diameter prior to forming. If tests on individual wires are required after stranding, the

48、 purchaser and manufacturer shall agree to the requirements prior to order placement.
