Electrical Properties of Sliprings
Standard sliprings are rated for 690 Volt AC and 900 VoltDC; Control Rings in block system for 500 Volts.
Indicated collector ring ampere capacities are for 60 %nominal rating.
200 Amp and 400 Amp collector ring sizes are used for 6/10kV high voltage applications. Reels beyond these capacitiesare available upon request.
Protection CodeSlipring enclosures are designed to IP 54; protected againstharmful dust deposits and splash water proof per DIN40050. Higher grade protection available upon request.
A thermostatically controlled heater is installed on high vol-tage reels (and can be supplied on standard reels) to pre-vent condensation moisture.
Drive System
The following drive systems are employed:
- Torque motor, squirrel cage type- Torque motor, slipring type with std. or step resistor- AC motor with magnet coupling
Further models from our wide range of heavy duty and highspeed reels include:- Torque motor, slipring type with electronic control- Hydraulic drive with constant torque- Hydraulic drive with variable torque for constant cable ten-
sion
Cable Payout
is normally following the technical information and drawingsof this catalog.
Other requirements can be fulfilled; e. g. opposite hand rota-tion.
Limit Switch Assemblies
for switching off travel and hoist motors with one or twosafety windings on the reel are optional.
In conjunction with torque control systems we do supplycam-type limit switches.
Accident PreventionAll moveable parts of the drive system, e. g. chaindrive arecovered in accordance with the accident prevention code.
Therefore, the cable reels can be installed in work areas aswell as traffic areas. Additional protective devices, such as acover for the revolving reel body itself, are to be furnishedand fitted at site.
Corrosion ProtectionThe random wrap reel series is galvanized. All other reelscome with one primer coat and one finishing paint of epoxy-resin RAL 2002 orange-red varnish; Motor and Gearings inRAL 5009 azure-blue.
Reel Selection
Choosing the proper cable reel from the VAHLE Reel Selec-tion Charts has been made as easy as possible.
All you have to know is:
Cable data- Wire size and number of conductors- Diameter- Weight- Min. bending radius
Active cable length Max. operating speed of your equipment
The capacities of the cable reels in this catalog are basedon cables listed in the Reel Selection Charts allowing onesafety winding for standard voltage or two safety windingsfor high voltage applications; considering an ambient tem-perature of – 10° C up to + 40° C and an acceleration factorof 0,2 m/sec2.
For other conditions, consult factory and use our que-stionnaire pages 6 & 7.
Cable Length
Reels are designed to handle a certain type and length ofcable in a specific manner. Never use reels for more cablethan outlined in the selection charts.
The total cable length required results from maximum pay-out length (active cable) plus reel installation height plus oneor two safety windings plus hook-up length for connections.
Installation Information
Installation instructions and operation manuals for commis-sioning advice and assistance are attached to each reelshipment and found in the slipring housing.

retrieve retrieve liftReel is mounted on the moving equipment, picks up cable from the floor or other surface. One- or two-way horizontal payout. The appli-cation becomes a modified retrieve lift when reel mounts too high for cable drag without guide.
retrieve retrieve liftMuch the same as above, however cable recovery from round support brackets or rollers at regular intervals;l1 for brackets max. 1 m, for rollers 1 up to 3 m.
horizontal stretch with reel on moving equipment horizontal stretch with stationary reelCable is suspended horizontally, supported only at both ends, allowing a sag (f) in relation to l or L whatever is longer.
vertical lift vertical retrieveReel is mounted overhead. Cable pays out and is retracted vertically. Total cable weight plus any extra load (pushbutton station, etc.)must be considered. The latter does not apply to case 9 where the reel is located below rather than above.
Legend to Drawings:l = operational (active) length of cablel1 = support intervalsL = max. length between reel and end of cableLF = feed point or connection to moving memberh = height of reel above recovery surfacef = cable sag
For applications 3 thru 7 and 9 and reels beyond thelisted capacities, please contact your local VAHLErepresentative or the factory.Use the reel data form on pages 6 & 7 of this catalog.Having all the facts will ensure determining of thebest reel for your specific requirement.
dragIn this case the reel is stationary. Cable is dragged overround supports or rollers to and from the reel, in one or twodirections (l1 ≤ 3 m).

FEATURES Magnet Coupling Series

19 12
These electric motor driven reels use permanent magnetcouplings for the required torque effect.
Two coupling sizes are available:
No. 1.8 for a constant torque momentNo. 7 for an adjustable torque moment
(by changing the airgap).
The adequate starting torque of the standard AC Motor inany cycling or voltage is higher than the magnet couplingtorque.
While the primary side works per the motor rotation (in thereeling up direction) the secondary coupling side rotates perthe travel speed of the moving equipment.
n = 0 standstilln = – retrieven = + payout
keeping always a minimum torque moment set by the fac-tory in addordance to the speed envisaged.
A back-stop device on the motor holds the cable in placewhen power is shut off.
Up to the certain air gap (torque moment) the coupling sizes1.8 and 7 can operate at 100 % DF e. g. the electric motorrunning continuously under power, as long as the movingequipment is in operation.
A drive-connected, intermittent service requires a built intimer maintaining cable pickup as the moving equipmentdecelerates after shutdown.
A few reel models, using coupling No. 7 require a payoutsensor detecting the rotation of the reel ensuring that thereel motor is energized during cable recovery and de-energized during cable payout. This results in energy sav-ings and extended unit life. See reel selection charts (*) andwiring diagram.

Careful treatment and long life of cable is achieved bystepless variable torque regulation. All dynamic loads arebeing considered.
Standard, robust AC motors are used and the frequencyinverter is easily programmable. Additional PLC’s are notrequired.
There is a considerable saving of electric energy over con-ventional drive systems (e.g. torque motors).
Model LTF - with frequency inverter drive,designed for heavy duty and high speedapplications.

Motor reels - Model LTF - with frequency inverter drive
Using fibre optic cables on motor reels for continuous datatransmission between rotating and stationary system partsrequires fibre optic links (usually 6 FO-elements 50/125 or62,5/125).
This unit guarantees an interruption-free performance totransfer data between computer interfaces, analogous mea-surings, video signals etc.
Cable Reels LT in use at a steel mill handlingcommunication cable.
A combined fibre optic-copper link is also available.
Recommendations and dimensions to meet your require-ments will be furnished on request.

Model HS - with electro-hydraulic drive for constant tor-que, designed to power moving equipment operating undersevere heavy-duty conditions at high speeds and usingheavy-gauge cable.
The hydraulic drive works elastically, thus minimizing cablestrain caused by abrupt starting, braking or during flipoverpoint operation.
Model HSB - with electro-hydraulic drive and variabletorque for constant cable tension is especially well suitedfor high-voltage cables and small cross section conductorsnot tolerating high mechanical stress.
Reels are designed for monospiral wrap with the elasticdrive adapting to the spooling diameter.
A taut and slack cable monitoring device is optional.

Model LT/S & HS/S - for level wind, one or multilayeroperation to handle extra long cable when there is no roomfor a monospiral reel.
These wide spools feature a cable steering and distributionmechanism allowing cable payout in a right angle or in par-allel to the reel axis.
Mainly meant for extreme heavy working conditions, theLT/S & HS/S kind of drive unit is choosen in accordance tothe application.
A taut and slack cable monitoring device is optional.
