NOTICE
As this catalogue is not intendedto cover all of LIBAN CABLES SAL possibilities inspecial cables manufacturing, the hereafter listing of the types of cables is not retrictivebut only indicative of the main and most current types we manufacture.
On the other hand, our specification sheets are inspired mainly from InternationalElectrotechnical Commision Specification (IEC) only in order to conform with thesustained trend, noticed both regionally and worlwide, towards these same IECsupposed to inspire any further standardization approaches.
Whereas, in facts some special cables may require special conception, fully within thecapabilities of LIBAN CABLES SAL, ISO 9001 certified, precisely because inposition to conceive / tailor your special needs.
That is why, while consulting this brochure, it is important to take into account that anycombination or change of the constructional details mentioned in this catalogue remainfeasible, on base of special conception / development, matching any special or differentspecifications.
Finally, and within our policy of constant improvement, we reserve the right to alter anypart of the information contained in this publication without incurring any obligation.In all cases this brochure being only indicative, and unless expressly agreed upon, itcannot be considered by any mean as contractual document.

1 INTRODUCTION
Devoted to the manufacturing of electric and telecomcables, Liban Cables is the first and largest supplier inLebanon and a leader in the Middle-East region.
Liban Cables was founded in 1968 by a group ofLebanese industrialists backed up by the technicalassistance of two international leading firms :
- Les Cables de Lyon - France
- Phelps Dodge - U.S.A
Staffed 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 request.
Early 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 request.
High 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). Liban Cablesproducts are particularly appreciated by administrationsand international contractors operating in the region andseeking reliable and direct supplies of power andcommunication cables.

Step by step, from raw material to final product, quality constitutes a major concern toLiban Cables.
Raw material are continuously and repetitively tested from trial orders till the last batchreceived afterwards.
In addition to the final tests carried out on finished products, work in process is alreadytested within two simultaneous procedures :
- A built in quality control system carried out by the production itself at any step ofwork in process.
- A parallel and contradictory procedure is also carried out on the same stages andproducts by independent inspectors reporting to the quality control service.
End users and/or third part inspection authorities are also constantly commissioning thefinished products and assessing the strict conformity to ordered specifications.
In fact, our ISO 9001 certification stated in Feb 1997 by the International CertificationNetwork (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 / 1997 / 7034, confirms thesoundness and the performance of the Quality System we apply for the Design, theDevelopment, the Manufacturing and the Marketing & Sales of all our products.

3 RECOMMENDED ORDERING PARAMETERS
For prompt quotation / supplies please make sure your inquiries and your orders aresecuring the following data :
1 - International or Special Standard. (Alternatively, the precise usage of thecable.)
2 - Rated voltage.
3 - 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.
10 - Required validity.

4.1 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 / 3
The voltage of the cable must be chosen according to the maximum voltage Um innormal working conditions, which must not exceed the rated voltage by more than 20%.
The following table gives the maximum permissible operating voltage relative to eachrated voltage (Uo / U).
4.2 DETERMINATION OF THE CROSS SECTIONAL AREA
The determination of the cross sectional area depends on the :
- Current carrying capacities in continuous loading,- Permissible short-circuit current,- Conditions of installation (temperature, spacing, ...).
4.3 CURRENT CARRYING CAPACITIES
The 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. 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 :

4.3.1. BURIED CABLES
The stated values are for cables or ducts placed in the ground at a depth of 800 mm ofaverage thermal resistivity of 100˚C.cm/w 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˚C.
Where the thermal resistivity is different (not 100˚ Ccm/w) the current rating shouldbe multiplied by the correction factors shown in the following table.
