2 NOTICE As this catalogue is not intendedto cover all of LIBAN CABLES SAL possibilities in special cables manufacturing, the hereafter listing of the types of cables is not retrictive but only indicative of the main and most current types we manufacture. On the other hand, our specification sheets are inspired mainly from International Electrotechnical Commision Specification (IEC) only in order to conform with the sustained trend, noticed both regionally and worlwide, towards these same IEC supposed to inspire any further standardization approaches. Whereas, in facts some special cables may require special conception, fully within the capabilities of LIBAN CABLES SAL, ISO 900 certified, precisely because in position to conceive / tailor your special needs. That is why, while consulting this brochure, it is important to take into account that any combination or change of the constructional details mentioned in this catalogue remain feasible, on base of special conception / development, matching any special or different specifications. Finally, and within our policy of constant improvement, we reserve the right to alter any part of the information contained in this publication without incurring any obligation. In all cases this brochure being only indicative, and unless expressly agreed upon, it cannot be considered by any mean as contractual document. 6

3 INTRODUCTION Devoted to the manufacturing of electric and telecom cables, Liban Cables is the first and largest supplier in Lebanon and a leader in the MiddleEast region. Liban Cables was founded in 968 by a group of Lebanese industrialists backed up by the technical assistance of two international leading firms : Les Cables de Lyon France Phelps Dodge U.S.A Staffed with qualified engineers and highly skilled technicians, our plant is located in NahrIbrahim at 0 Km from Beirut, where cables are designed and manufactured according to all international specifications : IEC, VDE, UTE, BS, and others on customer request. Early after its foundation, Liban Cables has become the major supplier of the Lebanese market in both the public and private sectors. The product range of Liban Cables covers all electric cables up to 45 KV, communications cables (copper and optical fiber) in addition to a wide variety of special cables manufactured on customer request. High quality cables, continuous developments of the production range, direct and fast shipments have contributed in rendering Liban Cables an important exporter for many countries on the three limitrophe continents (Asia, Europe, Africa). Liban Cables products are particularly appreciated by administrations and international contractors operating in the region and seeking reliable and direct supplies of power and communication cables. 7

5 QUALITY Step by step, from raw material to final product, quality constitutes a major concern to Liban Cables. Raw material are continuously and repetitively tested from trial orders till the last batch received afterwards. In addition to the final tests carried out on finished products, work in process is already tested within two simultaneous procedures : A built in quality control system carried out by the production itself at any step of work in process. A parallel and contradictory procedure is also carried out on the same stages and products by independent inspectors reporting to the quality control service. End users and/or third part inspection authorities are also constantly commissioning the finished products and assessing the strict conformity to ordered specifications. In fact, our ISO 900 certification stated in Feb 997 by the International Certification Network (EQNET) is certified by the French Association for Quality Assurance (AFAQ), the well known rigourous and independant accredited European assessor. This certification, under reference AFAQ Nº QUAL / 997 / 4, confirms the soundness and the performance of the Quality System we apply for the Design, the Development, the Manufacturing and the Marketing & Sales of all our products. RECOMMENDED ORDERING PARAMETERS For prompt quotation / supplies please make sure your inquiries and your orders are securing the following data : International or Special Standard. (Alternatively, the precise usage of the cable.) Rated voltage. Copper or Aluminium conductors. 4 Size of each conductor. 5 Insulation material : XLPE or others. 6 Number and identification of conductors. 7 Other requirements. 8 Packing. 9 Required delivery time. 0 Required validity. 8

6 4 GENERALITIES 4. CHOICE OF VOLTAGE The rated voltage is specified as Uo / U where : Uo is the rated voltage between conductor and screen or outer metallic protection. U the rated voltage between any two conductors. In three phase systems Uo is U / The voltage of the cable must be chosen according to the maximum voltage Um in normal working conditions, which must not exceed the rated voltage by more than 0%. The following table gives the maximum permissible operating voltage relative to each rated voltage (Uo / U). Rated voltage Uo / U (Kv).8 /.6 / 6 6 / / 5 / 0 8 / 0 Max. voltage Um (Kv) DETERMINATION OF THE CROSS SECTIONAL AREA The determination of the al area depends on the : Current carrying capacities in continuous loading, Permissible shortcircuit current, Conditions of installation (temperature, spacing,...). 4. CURRENT CARRYING CAPACITIES The heat produced by the cable under the set conditions must be able to dissipate to the ambient environment at any point of the cable installation; therefore the loading of the cable must be limited accordingly. The current carrying capacities shown in the electrical characteristics tables are calculated according to the internationally adopted method of the IEC publication 6087 for a maximum core temperature of 90 C, at the following installation conditions : 9

7 4... BURIED CABLES The stated values are for cables or ducts placed in the ground at a depth of 800 mm of average thermal resistivity of 00 C.cm/w and spaced so that the temperature rise in each duct has no effect on the other ducts ( space being greater than meter ), for a soil temperature of 0 C. Where the thermal resistivity is different (not 00 Ccm/w) the current rating should be multiplied by the correction factors shown in the following table. Correction factor for different soil thermal resistivity Nature of the soil Very wet soil Normal soil Dry soil Very dry soil Soil thermal resistivity C.cm/w Correction factor Where the temperature of the soil is different (not 0 C) the current rating should be multiplied by the following correction factors. Correction factor for different soil temperature Soil temperature ( C) Carrying core temperature ( C)

8 When several cables or ducts are laid underground with less than one meter spacing the current rating values should be multiplied by the following correction factors : Correction factor of proximity effect for underground cables Single or multicore cables Number of circuits Touching cables One diameter spaced cables a = D a = 0.m a = 0.5m a =.0m 4... CABLES LAID IN AIR : The stated values are for cables or ducts laid in air with an ambient temperature of 0 C and out of direct sunlight, spaced so that the temperature rise of individual cables has no influence on others. The spacing between adjacent cables is at least twice the cable or duct diameter. When the ambient temperature is different ( not 0 C ) the current rating values should be multiplied by the following correction factors : Correction factor for different ambient temperature Ambient temperature ( C) D = overall outer sheath diameter a = Space between cables Carrying core temperature ( C)

9 When several cables or ducts are grouped, the current ratings values should be corrected as follows : a D H SINGLE CORE CABLES Method of laying Touching One diameter spaced cables a = D Number of layers Number of ducts cables in horizontal layer cables in triangular formation MULTICORE CABLES Method of laying Touching One diameter spaced cables a = D Number of layers Number of ducts Note : the space H between layers must not be less than 0cm

10 4.4 Inductance The Inductance L depends on the geometrical characteristics of the cable as well as the disposition of conductors for unarmoured cables : L = Log Dm 0 ( mh / Km ) r where : r = Conductor Radius D = Distance between Conductors Single phase system Three phase system flat formation Three phase system trefoil formation D D D D D D Dm = D Dm =,6 D Dm = D For armoured Cables increase the inductance of about 0% Capacitance C =. 8 Ln D d d = Diameter of conductor ( including the eventual semiconductive layer ) D = Diameter of insulated Conductor 4.6 Conductors short circuit current : Current densities given in the table below are in (A / mm ), for a maximum condutor temperature of C at the end of the short circuit. Temperature of conductor before overload T ( C ) Current density ( A / mm ) Conductor metal Copper Aluminium overload time in secs For an overload duration (t) different than those figured in the above table, the correspondant current density is given by the following formula : Current density for a duration (t) = Current density for sec t
