MKHD/MKHF/MKHS Anti-condensation sections For combined indoor/outdoor applications use anti-condensation sections. They do not interrupt electric conductors. Contact sections, turntables, switches Powerail for working areas and transfer applications see pages 20 & 21 Sectionalizing Conductor dead sections are electrical interrupts of the conductor. Under normal operating conditions a cross over with collectors to switch the voltage off or on is only allowed with low power ratings (control current). The conductors can be seperated through air gaps (5 mm) or insulating pieces (35 mm). With the air gap the collector carbon bridges the gap, e.g. for mains. The insulating piece is longer than the carbon and each Powerail section can be separated electrically, e.g. for control. Collectors The current collectors are made of re-inforced polyester fiberglass, for high strength and light weight. Spring loaded carbon brushes maintain uniform contact. Connecting cables and hinged or flexible towing arms included.

AC: ΔU = √ 3 x I x l x Z DC: ΔU 1 =2 l x I x R ΔU = 2 ΔU ∧ 100 1 V ΔU 1 = Voltage drop [V] R = Resistance [Ω/1000 m] ΔU 2 = Voltage drop in % l = Power feed length [m] I = Ampere load [A] L = System length [m] With following system requirements double collectors have to be used: - Transfers with switches and turntables - low voltages, frequency controlled drives - Transmission of data- and/or emergency stop signals - high electrical loads The length of the collector cable may not exceed 3 m if the added overcurrent protection device is not designed for the load capacity of this cable. Please refer also to regulations VDE 0100, part 430 and EN 60204-32. Please note: For use in galvanizing and pickling plants, under agressive conditions and low voltage applications we would appreciate receiving detailled information,especially of the environmental conditions. For quotations and order processing including Powerail systems with curves, dead sections, turntables, switches etc. we require your drawings or sketches. Please use our questionnaire, page 35.

A diversity factor of 0,5-0,9 can be considered. The conductor size and/or number of feed points should be increased or booster cables should be used in parallel in case the drop is exceeding the limitations. 4
