current flowing in the cable both i

current flowing in the cable both in test and fault condition. A calculation report proving the chosen fittings and clamps shall be submitted, for Customer approval, by Supplier during execution phase.Cables shall be submitted to different changes of orientation, as shown in reference documents [10] to [12]. Radius of curvature during installation and in fixed position may be critical and shall be compliant with available space. The contractor shall indicate minimum radius of curvature allowed for each cable.6.6.1 Three-phase cable installation (Sections 2 and 3)Cables shall be suitably installed and transposed, if needed, in order to reduce electro- dynamic effects. The inductance of the cable is the origin of the limitation of the power available in the test area, therefore cables shall be fixed in a way aimed at minimizing as much as possible the mutual inductance between cables to avoid the loss of short-circuit power. The consequence is that cables are connected closed together and submitted to strong electro-dynamic stresses. The Contractor has to give the correct number of spacers and cleats which are necessary for the foreseen installation configuration.NOTE: the description given in the present par. 6.6 is purely indicative; starting from this base the Contractor shall make its proposal of installation to be approved by the Client.6.7 Cable jointsConsidering the foreseen cable system layout and the limited length of each circuit, joints are not allowed.6.8 Cable lifetimePower cables shall be designed in order to ensure, after 20 years of service, a dielectric withstand capability to its nominal dielectric stresses equal to 99%.6.9 Cable markingThe over sheath of the cable shall be permanently marked in English and Arabic language at interval of 1 (one) meter by indelible printing or embossing, with the following minimum information:• Rated voltage• Insulation material• Conductor material and size in mm2• Manufacturer’s name or trademark and country of origin• Year of manufacture• Metric indication and references to relevant IEC Standards The marking shall start at 50 cm from inner end of the cable.The over sheath of all cables shall be marked with the cumulative length at every one meter, with the highest length mark on the outer end of the cable. The length marking shall start at one-meter distance from the inner end of the cable.Cables that cannot by conveniently marked because a physical limitation of the outer surface, shall be provided with a printer tag or tape attached to the cable.
