Copper and aluminum are the most employed metals for conductors in the cables power production tecnology.Their application is due to different parameters as electric conductivity, density (mass per unit volium),breakingload and elongation, malleability, thermal conductivity, elastic module and finally metal cost-effective. Theshape of conductors and their rigidity or flexibility is designed in consideration of the final application and of therated voltage cable.For medium tension cable is very important a smouth outside surface metal conductor to reduce electricalinsulation stress. For the pourpose any MT conductor is compacted by special tools suitable to calibrate outsidediameter and surface. In all tables we report the nominal cables section expressed in mm2 but the realconductor size considered is difined Electrical Section that is guaranteed by means of check of the maximumappropriate electrical resistance at 20°C in compliance of technical standards.

METAL CHARACTERISTICS
When is necessary to improve a few basic metal characteristics is possible to lose or reduce significant otherproperties. However typical metal characteristcs ordinary way contemplated, over any global evaulation, areindicated in the table below.Copper results to hold the greatest electrical conductivity but despite that its price may be still high if comparedwith aluminium for example. Following information help you a fully technical evaluation.

Cu resistivity
Due to the above equivalence how to change an aluminuim cable in a copper cable and contrariwise:
example
Al cable size 240 mm2 • 0.61 = 146.40 mm2 Cu (mathematical size)consequently the nearest available standard size to use is 150 mm2 Cu
Cu cable size 240 mm2 : 0.61 = 393.44 mm2 Al (mathematical size)consequently the nearest available standard size to use is 400 mm2 Al
Strictly connected to metal market price an important save money may be achieved by to use aluminiumcables instead of copper cables. In this case a calculation of aluminium conductor size, bigger thancopper, is possibile by electrical equivalence formula:
METAL CONDUCTOR REPLACEMENT
UoEx = kV/mm
x In (R/r)
The HEPR insulation is extruded simultaneously with the conductor screen and the insulation screen.The surfaces between inner semicondutor layer and HEPR insulation and between insulation and outsidesemiconductor layer are not exposed to environment conditions. Triple steam or dry curing extrusion guaranteehigh products quality. Is known that the electrical stress is maximum at the conductor level surface anddecrease drawing up outside insulation layer.In order to avoid stress peak in the medium voltage cable compacted metallic conductors with homogeneousand smooth surface are employed. Besides that the extruded conductor screen allows an uniform electric fieldwhich contributes for a long duration cable life.The insulation thickness may be calculated by following formula.

Fire is one of the most danger for popolations and equipments especially inside structures and in any placewhere it may happen. Very frequently that is due to the very extensive use of cables. They can be an importantcomponents to trigger fire, carry flames everywhere, developping acid gasses and dark fumes very hazardousfor persons.In consideration of past tragic happenings have been developped special cables with particolar performancesreaction to fire as to design cables with components able to avoid issue aggressive substances underburningsevent without loosing or altering any basic feature.
Flame Retardancy - cables in compliance of standards country regualtions suitable to overcome specialresctrict propagation test on single cable or bunched cables with definite volium per meter of non metallicmaterial. Its behaviour is strictly related to the combustion quantity material exposed to the flame, temperatureand aeration.Corrosivity Combustion Gasses - not LS0H during combustion develop great quantities of corrosive andtoxic gasses. New generation cables reduce or entirely remove it.Intensity and Dark Smoke - under fire conditions not LS0H cables release dark smokes that prevent peopleevacuation, that has been restricted ta lot, as a special test able to verify residue light across the smokesshows.

ALTERNATIVE KIND CABLES
1- Particularly eligible for installations in contact with water and moisture contact thanks to longitudinallythermosealed aluminium tape screen absoluty safety of transverse tightness.
2- In any habitat place where a limited a EMF level is required we provide through the electrical balance ofconductor and cable screen.
3- Root Cable is a commercial brand cable in aluminium or copper conductor with a non metallic mechanicalprotection made-up of an under outersheath plastic layer able to cushion heavy blow and to safeguard thebelow metallic cable screen.
Alternative kinds of cable are possible to be engineered in order to ensure a long term service with largetolerability for specific working conditions as dry and wet ground, rain and snow, under-water without any cover,direct exposition to the sun, places where cables can be crashed into etc.Electromagnetic Fields (EMF) are one of the most technical matters that affect environment condition thatmay be supervised by an appropriate increase of the cable metallic screen.

4- Self supporting cables for overhead installations through aluminium steel cladding rope laid in the central ofthree single phases. That rope can be replaced with a non metallic rope. This involves a new cable design withan increase screen size to allow electrical current fault discharge.
5- Three-phases underground cable with additional cables service.
6- Composite MT and FO cable where three-phases power elements and telecomunication aggregate fiberoptic cable able to work under the same outersheath.

A few different types of armour can be designed as protection of cables against crahs ,bl ow, shock, cuts, abra s i o n se t c . F u rt h e rmore in order to avoid electrical induction in the single phase cables the armour must be made-up ofnon-magnetic metals as copper, aluminium, bronze etc..Steel braid armour - a few group of wires braided together in opposite way.Wires armour - a layer of round wires.Tapes armour - double tapes wrapped in the same direction in open helics, the second one to cover underlyings space.Corrugated armour - a single longitudinally smooth tape corrugated by a special tool.Flat wires armour - a layer of wrapped flat wires with a contra ry tape wrapped in open helics.
For any operator in a market where there is in force AWG system the following table can be used to turn mm2to AWG or CM and contrariwise. Please keep in consideration some ineluctable approximate calculation dueto standard metric system size.

STORAGE AND HANDLING
The drums storage and movement shall be carried out with crane or forklift truck. It is not allowed to drop drumsfrom the truck to the floor. All cables during transport and handling can be demaged so we suggest to verifybefore and during installation procedure any possible demage to avoid heavy problems during cable workinglife. For the benefit of the workers involved in electrical work is absolutely necessary to observe some safetyrules normaly indicated on the local still in force standards.Do not remove staves and cable end caps until the cable will be laid down. If you cut a piece of cable leavingthe rest in a open stock put on again ends protections. Unwind and rewind cables as shown in the pictures. Incase of transfering from one drum to an other remember the minimum bending cable radius and consequentlythe barrel drum diameter.
INSTALLATION
We summarize some rules to be observed during the installation of MV cables for fixed layng. In order to pro-vide easy operations we suggest do not work at cable temperature below than 5°C. Cables bending radius areindicated in Range and Dimensions tables and they must be to value carefully. For unarmoured cables and inorder to pull cable inside pipes or trench it is advisable to apply the pool force on the conductors being carefuldo not exceed 5 kg/mm2 of total area for copper cables and 3 kg/mm2 for aluminium cables.
Example:copper cable 1 x 240 mm2: max pull force kg 1200 aluminium cable 1 x 240 mm2: max pull force kg 720copper cable 3 x 240 mm2: max pull force kg 3600 aluminium cable 3 x 240 mm2: max pull force kg 2160
For steel cable armour the strain rope will be applied to the armour while the pool force by steel braid is advi-sable only for limited efforts.If there are curves along the lay route must be placed a sufficients conveyers, for example at the entrance ofpipes, suitable to keep the cable in the right direction line in order to avoid to exceed the maximum pulling loadallowed.
Concerning overhead cables any strain will be charged on the supporting rope for installaion operations andduring working time.

Besides data reported in this booklet is always important to consider the effects of thermal dissipation.All installations in parallel trefoil must be realized with maximum care in order to aim the most balanced char-ge distribution on the cables connected to the same phase.Therefore please consider the following infomation:
• all cables must have the same metal conductors• all cables must have the same lenght and section• the bundle cables must be made-up following R, S and T phases system as indicated on page 29• the cables must be properly spaced • right and balanced connections to the cables terminals
