BS EN 3719:2018EN 3719:2018 (E) 5 4.2 Material for individual strand

30、s and code The individual strands may be: aluminium alloy un-plated (code A); aluminium alloy with tin plating (code B); 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 pla

31、ting is authorized, the thickness shall be sufficient to comply with the tests specified 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 i

32、ndividual strand shall be at least 105 MPa (105 N/mm2). 4.4 Construction of conductors 4.4.1 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

33、between 8 times and 16 times the maximum diameter of this conductor. For sectional areas 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 t

34、imes the diameter of the concentric or bunched conductor in question. The lay for concentric (or bunched) conductors, measured over the outer layer of the conductor, shall be between 8 times and 16 times the maximum conductor diameter. In all cases the lay of the outer layer shall be left-hand. 4.4.

35、2 Joints The distance between two (2) joints in individual strands shall exceed 3 m, measured between different strands. Only butt joints shall be used. 2) Or 30 m2/km. BS EN 3719:2018EN 3719:2018 (E) 6 4.4.3 Compaction Plated aluminium alloy: Compaction of the conductor, causing deformation of the

36、strands with damage to the plating, is not permitted for aluminium alloy using plating (codes B, C or D) (see 4.2). Un-plated aluminium alloy: Compaction of the conductor is permitted except if causing deformation of the strands or surface damage for aluminium alloy (code A) (see 4.2). A minimum com

37、paction rate of 95 % is acceptable. NOTE The minimum compaction rate (%) is defined by: the diameter of the compacted conductor by the diameter of the un-compacted conductor (x 100). 5 Required characteristics See Table 2 or Table 3.
