12、 Publication. prEN 3719:2016 (E) 3 1 Scope This standard specifies the dimensions, linear resistance, mechanical characteristics, construction and mass of conductors in aluminium or aluminium alloy for electrical cables for aerospace applications. It applies to stranded conductors with nominal cross
13、-sections of 5 mm2 to 107 mm2 inclusive. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the
14、 referenced document (including any amendments) applies.

16、initions and symbols given in EN 3475-100 apply. 4 Conductor materials and construction 4.1 Materials The conductors in accordance with this standard shall consist of individual annealed aluminium alloy EN AW-1110 Al 99,1, (see EN 573-3 and EN 1715-2) or aluminium alloy strands with the following co

18、erial for individual strands 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
19、 m for nickel. When tin plating 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 %. Th
20、e tensile strength of each individual strand shall be at least 105 MPa (105 N/mm2). 4.4 Construction of conductors 4.4.1 Lay length Up to 9 mm2 cross-section inclusive (code 090), concentric conductors are used. The lay for the strands of a concentric conductor, checked over the outside layer of a t
21、est piece 1 m long, shall be between eight times and 16 times the maximum diameter of this conductor. For sectional areas between 14 mm2 and 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 bunch
22、ed conductors shall not exceed 30 times 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 eight times and 16 times the maximum conductor diameter. In all cases the lay of t
23、he outer layer shall be left-hand. 4.4.2 Joints The distance between two joints in individual strands shall exceed 3 m, measured between different strands. Only butt joints shall be used. 2) Or 30 m2/km. prEN 3719:2016 (E) 5 4.4.3 Compaction Plated aluminium alloy: Compaction of the conductor, causi
24、ng deformation of the 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) (s
25、ee 4.2). A minimum compaction 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.
