3 - Les Cables de Lyon - France- Phelps Dodge - with qualified engineers and highly skilledtechnicians, our plant is located in Nahr-Ibrahim at 30Km from Beirut, where cables are designed andmanufactured according to all internationalspecifications : IEC, VDE, UTE, BS, and others oncustomer after its foundation, Liban Cables has become themajor supplier of the Lebanese market in both thepublic and private sectors. The product range of LibanCables covers all electric cables up to 245 KV,communications cables (copper and optical fiber) inaddition to a wide variety of special cablesmanufactured on customer quality cables, continuous developments of theproduction range, direct and fast shipments havecontributed in rendering Liban Cables an importantexporter for many countries on the three limitrophecontinents (Asia, Europe, Africa).

4 Liban Cablesproducts are particularly appreciated by administrationsand international contractors operating in the region andseeking reliable and direct supplies of power andcommunication cables. 7 ASSURANCERECOMMENDED ORDERING PARAMETERSGENERALITIES :Choice of voltageDetermination of the cross sectional areaCurrent carrying capacitiesBuried cablesCables laid in the airInductanceCapacitanceConductors short circuit currentScreen short circuit currentMinimum bending radiusOUR TYPE AND CODE DESIGNATIONSINGLE AND THREE CORE MEDIUM VOLTAGE CABLESA ccording to international standard IEC ( ) KV Cables, XLPE insulated, PVC or PE sheathedXLPE insulated, screened, PVC or PE sheathed cables forvoltages up to and including 36 Bundled overhead conductors (Torsade)12/20 (24)

8 The following table gives the maximum permissible operating voltage relative to eachrated voltage (Uo / U). DETERMINATION OF THE CROSS SECTIONAL AREAThe determination of the cross sectional area depends on the :- Current carrying capacities in continuous loading,- Permissible short-circuit current,- Conditions of installation (temperature, spacing, ..). CURRENT CARRYING CAPACITIESThe heat produced by the cable under the set conditions must be able to dissipate to theambient environment at any point of the cable installation; therefore the loading of thecable must be limited accordingly.

9 The current carrying capacities shown in theelectrical characteristics tables are calculated according to the internationally adoptedmethod of the IEC publication 60287 for a maximum core temperature of 90 C, at thefollowing installation conditions :4 GENERALITIESR ated voltageUo / U (Kv)Max. voltageUm (Kv) / / 66 / / 1512 / 2018 / BURIED CABLESThe stated values are for cables or ducts placed in the ground at a depth of 800 mm ofaverage thermal resistivity of 100 and spaced so that the temperature rise ineach duct has no effect on the other ducts ( space being greater than 1 meter ), for a soiltemperature of 20 the thermal resistivity is different (not 100 Ccm/w)
