C-Rail [Festoon] System

C-Rail Festoon System

Festoon systems are used to electrify various types of mobile equipment. They can be designed not only to support and protect flat and round electrical cables, but air and water hoses as well. Systems can be pre-assembled at the factory to ease installation and reduce time. Festoon systems are typically used on overhead cranes, port cranes and other material handling applications. We also have a solution for extremely corrosive environments. Our product range includes accessories for the various cable management systems. Standard length 4.5 meters.

Conductor Bar Table

Voltage Drop

The voltage drop on our conductor system should be restricted to 2.5 to 5% of the nominal supply voltage.

Three Phase Alternating Current (3ph AC): ΔU = √3 × FL × I_total × Z (Volts)
Single Phase Alternating Current (AC): ΔU = 2 × FL × I_total × Z (Volts)
Direct Current (DC): ΔU = 2 × FL × I_total × R (Volts)

Where:
ΔU = Voltage Drop
I_total = Total Currents [Amps]
R = Resistance of conductor [ohms/meter]
Z = Impedance of conductor [ohms/meter]
FL = Feeder Length [Meters]
L = System Length [Meters]
Un = Operating Voltage

If the voltage drop is too high, then either the number of feed points or the cross section of the conductor rail should be increased to reduce the voltage drop along the system.

Multiple feed-in points

  • FL = L     feed from one end
  • FL = L/2   feed from the center
  • FL = L/4   feed from both ends
  • FL = L/6   two feed-in positions, L/6 from each end
  • FL = L/10   feed-in points in the center and at L/10 from both ends
Feed positions diagram

Other possibilities to arrange the feed positions can be selected. For very high current, cables can be connected in parallel (booster cables).

Note: When considering ΔU calculations any effects of additional temperature caused by either heating of the conductor due to duty cycle, or a rise in ambient temperature above 35°C must be considered.
