Compounds for Nexans handling cables
1. GeneralitiesThe selection of the correct compound assume thedetailed analysis of the application where the cableis used.
In the case of flexible, movable applications such asin cranes the compounds for insulation, semi-conductive layer, outer and inner sheaths arechosen by Nexans for several factors as highmechanical properties, chemical resistance andthermal requirements.
Nexans is familiar with the high performancerequirements in flexible applications combined withhigh mechanical stress. Due to this, Nexansespecially uses in our RHEYFIRM®(RTS) only high-grade rubber insulation such as RHEYCLEAN®®-HV.
This special compound, manufactured in severalversions allows to reduce wall-thickness for thedifferent voltage rates from 6 to 30 kV.We generally use compounds that exceed requiredstandards like VDE.
In our product range RHEYFIRM®(RTS) andRHEYCORD®(RTS) we only use the compound5GM5 instead of 5GM3. This high gradecompound has a much higher tensile strength, tearresistance and abrasion resistance than the morecommonly used compound 5GM3.
Additional advantages of this special outer sheathcompound are high flame retardancy properties,ozone, weather and ageing resistance. Furthermoreit has excellent elastic behaviour even in lowtemperatures.
NEXANS distinguish compounds betweenThermoplastics and Elastomerics.
Both compounds are used for insulation, inner andouter sheaths. The graph and table on the followingpages give a short introduction to compound andexplain the typical and most important characteristicsfrom several materials used in Nexans handlingcables.

Strength members in flexible cables could be placed indifferent arrangements:
• outside the cable
• elements (e.g. braid) between inner and outer sheaths
• in flat cables besides the cores
• in the center of cable.
The effects of a strength member are:
• to take over a part of the pulling force to reduce themechanical stress from the copper conductor.
It ensures compliance with VDE 0298 standard part 3of 15 N/mm2 (referring to the copper cross-section ofthe main cores).
• to reduce the risk of a corkscrew-effect. That wouldbe caused by turning off the stranding from the coresand simultaneus turning on in an other part of the cable length.
• to reduce the risk of torsion in a cable by a reductionof the tensile force of the stranding conductor.
The most common strength members are:
• Steel rope
• Polyamid/ polyester ropes
• Aramid/ kevlar yarns
• Natural fiber e.g. sash line
• Coated E-glass
Depending on the detailed application of the flexiblehandling cable, physical characteristics like elongation[%], elastic stability (N/mm2), breaking load (kN),laying types and reversed bending properties of thedifferent strength members must be analysed.
Other integrated elements like reinforcement braidsused as strength member, relieve the conductor afterstress application. The strength members used byNexans relieve the conductor instantaneously with stressapplication.

Anti-Torsion Braid
Torsional stresses is caused by different conditions:
In most flexible handling cables, we use an anti-torsion braid. The anti-torsion braid consist of synthetic threads witha very high tensile strength. It is embedded between inner and outer sheath to prevent twisting, loops, push off theouter sheath and “corkscrew-effects”.
• Changes of direction into different planes
• Non aligned guide pulley
• Sloping cable guide into the deflection pulley
• High dynamic stress
• High tensile load of the cable
Anti-torsion braid in a RHEYFIRM®(RTS)
Criterias to build up a heavy duty reinforcement:
• A good chemical bonding between synthetic threadsand sheath compound
• Braid angle
• Braid coverage percentage
• Material of reinforcement
• Shear resistance of the reinforcement element

Voltage Drop
Voltage drops are determined by using the following formula:
Δu = b x l x iB ( R cos ϕϕ + λλ sinϕϕ )
With:
ΔΔu voltage drop (in Volts)b coefficient equal to √3 for three-phases circuits, or 2 for single-phase circuits
R electrical resistance of conductors in normal service (in �/km)l straight length of the wiring systems (in km)cos ϕ power factor, if no precise details, the power factor is taken equal to 0.8
(sin ϕ= 0.6)
λ reactance per unit length of conductors (in �/km)iB current value (in Ampere)
For the application of the formula it is necessary toknow the exact cable specification.
For a fast calculation of the section it is recommendedto use the following tables which give the value of the voltage drop, available for most of the low voltagecables and for different values of cos ϕ.
Voltage drops are calculated for a three-phasescircuit:
• 3 or 4 copper cores cables• 3 single cores cables

BUS SystemData transmission
BUS Systems are used as a communication mediumfor sectored actuators, sensors and steering in theautomation industry and where electronic modules
have to be connected easily. Only one cableconnects all components.
Field bus is the generic name for all bus systems which are used for the metrology, steering and controllingengineering. These are:
• CAN• ProfiBUS• InterBUS• ASI BUS
According to DIN (German Institute forStandardization) standard a field bus in generalshould transmit a small volume of data in fast timeseries on a digital compare between sensors,actuators and steering. as the requirements to the bussystem depends on the level of automation, there is
no field bus which can solve all tasks optimaltogether.Following table shows a short overview of the mostimportant features of the three most popularBUS systems:

Optical Fibers
General OverviewOptical fibers are mainly used to transmit informationover long distances and with high bit rates. Theirbenefits are numerous: the signal transmitted on thefiber is not disturbed by any electromagnetic wavecreated by power cables or electric machines. It alsoprovides more security, as these cables can be fullydielectric. Besides, they provide a weight and spacesaving due to their small diameter, only 250 μm.
Different fiber types are available:
• Multimode fibers are used for Local Area Networks(LAN) where the network links can be up to 2,000meters. Two standard sizes of core are offered: 62.5 μm and 50 μm (with better performances).Multimode fibers have a graded index profile toreduce the dispersion of the signal during thetransmission. The high size of the core is interestingfor easy connection and does not require high costtest equipment.
• Singlemode fibers are able to transmit over longerdistances. The installation is more delicate as theyhave a smaller core of 9 μm. This implies moreprecise connectors and test equipment.
Coating
Cladding
Core
An optical fiber is made up of three main parts: thecore, the cladding and the coating.In the center, the “core” is made of doped silica andis surrounded by the “cladding”, made of naturalsilica.The light signal propagates along the core and thesignal is reflected on the surface between the coreand the cladding.An acrylic “coating”, generally made of two layers,is protecting the sillica part against abrasion duringinstallation.

Optical fibers are used at specific wavelength.Multimodes fibers are mainly used at 850 nm and1,300 nm and Singlemode are used at 1,310 nmand 1,550 nm. The attenuation performances arebetter at the higher bandwidth with consequentlyimproved transmission performances.Optical fiber can be provided with differentcharacteristics. Indeed the performance need forfiber in patch cord or fiber over one kilometer linkare obviously different. The fiber choice is based onoptical parameters such as attenuation, bandwidthperformances and chromatic dispersion.Different international standards are available todescribe the optical fiber characteristics: ITU G652for Singlemode fiber and IEC 60793-2-10 forMultimode fibers are worldwide references.
On a global network point of view, although the costof multimode fiber is more important than thesinglemode’s, the complete system is more economic.Indeed Multimode fibers are used with cheaptransmission components LED(1) or VCSEL(2) whilstSinglemode fiber operates with more expensiveLASER.

Nexans are able to preassemble optical fibers withplugs, we can provide this service in our factory or on site. A fiber optic connector is a non permanentjoin between two fibers.
In the optic connector systems gives a plurality toconnector, they are not compatible among onanother. It is recommendable to use ST connector orE2000 connector for reel and flexible cables withintegrated fiber optics.
A high quality connetor is required to achieve the bestpossible transfer of light signal between fibers.
An E2000 connector is a special connector with highlevel attenuation coefficient. This connector is suitablefor multimode fiber and singlemode fiber.Due to the code system, this connector is very userfriendly and can also be fit as a single connector orduplex connector The built-in filler cap protects the ferrule againstcontamination. The filler cap open/close during theconnector plug in/out.

Splicing
GeneralitiesFrom an economical point of view it only makessense to repair or splice handling cables having alarge conductor size. For implementation of spliceswell-founded knowledge of the fitter is needed.Furthermore for a bunched conductor splice avulcanizing machine for the vulcanisation ofelastomeric compounds is required.
The fundamental principle of splicing is to build anexact reproduction of the handling cable design(including the outer diameter) and the flexibility.
Pictured below, for a HV reeling cable, a shortintroduction shows the different phases of a repair.
First step is to strip-off the outer and inner sheaths.Further the bunched conductor has to be weldedstrand by strand, and layer by layer.
After applying and vulcanization of the inner sheaththe reinforcement will be wrapped.
Vulcanizing machine
By using different material tapes, we rebuild thetriple extrusion:• semi-conducting inner layer• insulation• semi conducting outer layer
Finally the outer sheath will be taped till the equaldiameter of the original cable.

Mechanical tests for flexible handling cables:“Handling Application Center”
GeneralitiesIn Nexans factories, strict quality control is one of themost important tasks to ensure a long-life term of ourproducts.Due to the high mechanical, torsion and tensilestresses appeared in handling applications, Nexanscarry out extreme mechanical type tests before a newproduct range is introduced into the market. The testconditions are much more harder then the reality inthe application.
Climate-tests, continous-tests for artificial ageing,mechanical and chemical compound properties (e.g.tensile strength, elongation, density, tear resistanceand abrasion, oil, ozone, UV resistance) serve toincrease the operating period of our products. Allthese tests are the basis for Nexans to improve thehigh quality level and cable performance.

Installation and Laying Instructions
Long-life terms of flexible reeling cables in cranes andother handling systems depend on cables installationand laying in a professional way. To ensure that, you have to respect the followingrules:
The most professional and safety way to avoid torsionstress is to lay the complete cable length from thesupply drum over support rollers on the ground withunfixed ends. If this is not possible, in case of lessspace, lay up the cable like in the below mentionedways.
WRONG RIGHT
Changes in directions must be avoided.
To traverse a Nexans flexible cablelength (left hand laid) on a cylindricalreel, you must start on the left side of thereel for winding up as shown on thepicture.
Feeding / Anchoring Systemsfor reeling cables
GeneralitiesTo ensure an optimum result regarding the service life of reeling cables, some important instructions must benoticed in the various methods of feeding/anchoring systems.
Center feedingIn many installations the anchoring device is located at thecenter of the guideway. Flexible reeling cables are normallyconnected over the entry bell through the underground centerpoint. To guaranty an effective strain-bearing, the flexiblehandling cable must be turned at least 2 1/2 times around thestress-bearing drum.
The advantage of the two-way center point anchoring is theshort cable length in comparison to an end anchoring device.Critical points in center feeding system are the dynamic loadpeaks due to the change of direction.
End anchoring deviceIn opposite to the center feeding system, the completeinstallation including e.g. guideway, device and powersupply is appropriate overground. To avoid dynamic stress due to tensile load in the cable.Nexans recommends to use:• stress bearing drums, • and / or• cables with integrated strength member
Anchoring vertical drum spreader cableIn the case of anchoring vertical spreader cable, the stressbearing drum is placed on the top of the spreader. Nexansrecommends in this application, stress bearing drums insteadof cable grips or other cable anchoring system. For a perfectoperation it is important to turn the cable at least 2 1/2 timesaround the stress bearing drum.
