BS

22、 EN 3719:2010EN 3719:2010 (E) 5 aluminium alloy with silver plating (code C); aluminium alloy with nickel plating (code D). Plating thickness shall be at least 1,0 m for silver and 1,0 m for nickel. When tin plating is authorized, the thickness shall be sufficient to comply with the tests specified

23、in EN 3475-506 and EN 3475-507. 4.3 Aluminium or aluminium alloy The maximum resistivity shall be: 3,0 10-8 m. 2) The elongation at rupture for each individual strand shall be 10 %. The tensile strength of each individual strand shall be at least 105 MPa (105 N/mm2). 4.4 Construction of conductors 4

24、.4.1 Lay length Up to 9 mm2cross-section inclusive (code 090), concentric conductors are used. The lay for the strands of a concentric conductor, checked over the outside layer of a test piece 1 m long, shall be between eight times and 16 times the maximum diameter of this conductor. For sectional a

25、reas between 14 mm2and 107 mm2(codes 140 to 107), the conductor comprises concentric or bunched conductors twisted together. The lay of the strands for the basic concentric or bunched conductors shall not exceed 30 times the diameter of the concentric or bunched conductor in question. The lay for co

26、ncentric (or bunched) conductors, measured over the outer layer of the conductor, shall be between eight times and 16 times the maximum conductor diameter. In all cases the lay of the outer layer shall be left-hand. 4.4.2 Joints The conductors shall be free from any joints. Each strand comprising th

27、e conductors may, however, include soldered or brazed joints. For strands with a diameter of 0,25 mm or greater, butt joints shall be used. The distance between two joints in individual strands shall exceed 3 m, measured between different strands. 4.4.3 Compaction Compaction of the conductor, causin

28、g deformation of the strands with damage to the plating, is not permitted. 5 Required characteristics See Table 2. 2) Or 30 m2/km.
