OPEN CONDUCTOR SYSTEMS

General VAHLE copperhead conductors were invented in ���� by engineer Paul Vahle. The T-profile, with their attached copperhead, replaced conventional bare copper wires, which encountered frequent contact difficulties, considerable spark formation and wire breaks. Attaching a copper profile to a T-shaped steel foot achieved a level of mechanical stability which provided safe contact between conductor and current collector . This results in a higher service life of the system, wear to the copper conductor is hardly detectable. As a result of continual development, our conductors and...

IEC – ( excerpt) This standard applies for the use of electric and electronic equipment and systems for hoisting gear and corresponding equipment. Conductor lines and slipring bodies Protection against direct contact Conductor lines and slipring bodies must be installed or enclosed to ensure that protection is provided against direct contact during usual access to the lifting gear, e.g. over the track platform or crane carrier platform by one of the following protective measures: Ǯ 3 URWHFWLRQE\SDUWLDOO\LQVXODWLQJWKHDFWLYHSDUWV This is the preferred measure.

Phase distance (holes in the support brackets): ��� mm with low voltage, ��� mm with medium voltage up to �� kV. In confined space conditions, the phase distance of conductors L ��, A �� and C �� must be no less than ��� mm and no less than ��� mm for all other conductor types. The support brackets must be aligned during assembly so that the conductors...

Selection of conductors In order to simplify the selection of the conductors and current collectors, depending on ambient conditions, there is a table for selecting conductors on this page and a table for selecting current collectors on page 32. In addition to the electrical layout, the tables will assist in choosing the correct conductor quickly. These tables limit the dierent conductors in their respective areas of application and provide an overall overview of their application depending on the ambient temperature. In steel mills with a high degree of particle contamination, note F...

Checking voltage drop for start-up current The position of the feed point can initially be determined according to on-site circumstances, usually at the end of the system (end power feed). If this value is exceeded, the voltage drop can be reduced by changing the power feed length (l) or by arranging additional feeds. If necessary, the next larger conductor may even have to be selected. If nothing else is specied, a guideline value for the max. voltage drop in the conductor of 3% of the nominal voltage can be assumed.
