BASIC DESCRIPTION

The Copperhead Conductor Rail was invented by PAUL VAHLEin the year 1912, and from this beginning the VAHLE COMPA-NY continuously improved and developed the many Rail Sys- tems, detailed in this catalogue.The “T” or “hollow T” section and the extruded copperhead isdrawn through a special die, which compresses the copperflanges around the dovetail head of the rail, connecting the twocomponents to a 100 % rigid unit.The well-known VAHLE Copperhead Conductor rails representa neat and compact arrangement and have proven an out- standing success for industrial safe power feeding of:Travelling industrial cranes, Loading bridges, Container handlingequipment, Monorails, Industrial hoists, Coking machinery andmany other applications.The VAHLE Copperhead Conductor Rails are available in sizesto meet individual current requirements from 200 to 1,500 Amps. Fibreglass-Copperhead Rails are preferably used for applica-tions in corrosive atmospheres and in locations with high humidity. Aluminium-Copperhead Rails are very economical due to thelight weight of the Aluminium and its high conductivity. Solid-Copper Rails are recommended for heavy duty currentrating and for humid locations.The rails are supplied in 7 m (23’) and 14 m (46’) standardlengths, drilled at either end for joint plates or expansion connectors manufacturer. Shorter lengths are available to coincide with your run way lengths requirements.We produce a complete range of Accessories, Insulators andCurrent Collectors.Low weight of rails and saving of steel superstructure andspace.Variation in temperature and resulting expansion and contrac-tion is compensated by standard expansion joints.If required, VAHLE Copperhead Rails can also be supplied bentto your specification.Heating systems are available for all VAHLE Rails. For Ducting Systems and Housings incorporating VAHLE Railsand Accessories see separate catalogue No. 5 -Heavy Enclosed Conductor Systems.

SOME ADVANTAGES OF VAHLE RAIL SYSTEMS

With VAHLE-Systems you eliminate all drawbacks inherent in the conventional design of trolley wires, steel angles and steelrails.Copperhead Rails ensure an efficient and continuous contact.There is no sparking.The easy maintenance is a proven low factor.No losses due to interruption of service, no downtime.Negligible wear - almost unlimited life of conductors.Much lower resistance between copperhead and carbon pick-up industrial shoe. The main users are:Steel mills, Coking plants, Gas works, Cement indus-tries, Ship yards and Dockside enterprises.
