26、ss-section throughout the entire length of the cable. The surface of the cable shall be smooth and comply with the requirements in respect of identification. The materials used shall be unaffected by corrosion and shall be resistant to the effects of mould fungus and similar micro-organisms. 4.3 Con
27、struction of the cables 4.3.1 General The operating temperature of the wires shall not be lower than the maximum operating temperature of the complete cable. 4.3.2 Cable lay The lay length of the outer layer shall not be less than 8 times and not more than 16 times the nominal diameter of the cable.
28、 The core shall not be spliced. 4.3.3 Screened cables 4.3.3.1 General The individual strands used for the screen shall be free from kinks, loops or breaks; their surface shall be free from corrosion and other contamination. They shall satisfy the mechanical tests in EN 3475-505 to EN 3475-508 before
29、 use. The screen shall be in contact with all the cabled cores. Where spiral screening is used the lay direction shall be contrary to that of the cables cores. 4.3.3.2 Joints Joints in the individual strands of the screen shall be made by soldering or by laying the individual strands to- gether over
30、 a length of at least 10 mm. There shall be no more than one joint per 3 m cable length (measured between different individual strands). 4.3.3.3 Braid screen pushback capability In accordance with test 6.41. 4.3.3.4 Angle of spiral screening or braiding The angle of spiral screening or braiding (as
31、shown in Figure 1), measured against the longitudinal axis of the cable shall be at least 10.

32、overage of at least 90 % for spiral screening and at least 85 % for braiding, these values being determined by the following formula: S = lay length of screen in mm D = diameter under screen in mm (for cables with 2 or more cores without fillers: D = ( + N) b / d = diameter of screen strand in mm N
33、= number of cores n = number of strands per carriers B = diameter of core in mm Z = total number of carriers F = filling factor = optical coverage U = see Figure 1. U = nd / sin = see 4.3.3.4. = 90 Figure 1 Cable covering The screen coverage is calculated using the following formula: for spirals: U
34、= (D + d) and S = (D + d) tan F = U Z / U = nd Z / (D + d) sin = F 100 (%) for braids: U = (D + 2d) and S = (D + 2d) tan For braids, the filling factor F and coverage , taking into account both braiding directions and a symmetrical braiding pattern are: F = (U / U) (Z / 2) = nd / (D + 2d) sin (Z / 2
35、) = F (2 F) 100 (%) 5 Required characteristics The characteristics of the cables, tested according to the methods described hereafter shall comply with the values given in the product standard.
