The surface of conductive materials used shall be free from corrosion and other contamination. Insulation and others materials shall have no corrosive effect upon the conductors and screens

20、and shall not be susceptible to attack by mould and other micro-organisms. 4.3 Construction of cables 4.3.1 General The permissible operating temperature of conductors shall not be lower than the maximum operating temperature of the cable as a whole. 4.3.2 Cabled cores The lay length of the outer la

21、y shall not be less than eight times and not more than 16 times the nominal diameter of the cabled cores, except if a different value is necessary to maintain the required characteristics. The core shall not be spliced. Where filler cores are used, this shall be specified in the product standard. Th

22、e assembly may be held together with an overall wrap. 4.3.3 Screened cables 4.3.3.1 General The construction shall conform to the product standard. Depending on protection level, the screening may be composed of: one or several spiral layers; one or several braids made using strands or strips; one o

23、r several metallic or other strips; one or several layers of extruded c onductive or non-conductive materials; a combination of the above. The screening may be individual and/or overall. The individual strands or strips used for the screen shall be free from kinks, loops or breaks. Except when parti

24、cular materials are used, they shall conform to standard EN 2083 or EN 4434 or shall satisfy the mechanical tests in EN 3475-505 to EN 3475-508 before use. Where spiral screening is used, the first lay direction shall be contrary to that of the cabled cores. 4.3.3.2 Joints Splices of the individual

25、strands or strips may be effected by brazing, soldering or folding in. There shall be no more than one splice per 3 m cable length (measured between different individual strands or strips).
