VAHLE Conductor Rails & Mobile Electrification

Paul Vahle GmbH & Co. KG traces its manufacturing heritage back to 1912, when visionary engineer Paul Vahle invented the world first copper conductor rail in Kamen (North Rhine-Westphalia, Germany). This landmark technological innovation revolutionized electrical power feeding across heavy foundry cranes, open-pit mining shovels, and automated conveyor monorails by replacing hazardous bare hanging wires with guided insulated conductors. Over more than 110 years of relentless research and development, the family-owned enterprise has evolved into a preeminent global technology leader in mobile electrification, high-speed data transmission, wireless inductive power, and optical absolute positioning.

Engineering Legacy of Paul Vahle (Pioneering Mobile Electrification Since 1912)

Paul Vahle GmbH & Co. KG traces its manufacturing heritage back to 1912, when visionary engineer Paul Vahle invented the world first copper conductor rail in Kamen (North Rhine-Westphalia, Germany).

This landmark technological innovation revolutionized electrical power feeding across heavy foundry cranes, open-pit mining shovels, and automated conveyor monorails by replacing hazardous bare hanging wires with guided insulated conductors.

Over more than 110 years of relentless research and development, the family-owned enterprise has evolved into a preeminent global technology leader in mobile electrification, high-speed data transmission, wireless inductive power, and optical absolute positioning.

Headquartered with advanced automated manufacturing plants and an international R&D center in Kamen, VAHLE operates under stringent DIN EN ISO 9001:2015, ISO 14001, and ISO 50001 certifications.

Advanced plastic profile extrusion, high-precision automated copper stamping, and rigorous conductivity testing ensure flawless performance across harsh factory conditions.

Today, VAHLE maintains thirteen direct operating subsidiaries across North America, Europe, and Asia, powering automated container ports, metal smelters, and automotive assembly lines in more than fifty industrialized nations worldwide.

Single-Pole Insulated Conductor Rails U10 and Enclosed Compact Systems KBH

The single-pole insulated conductor rail families U10, U15, U20, and U35 represent a world benchmark in electrical safety for mobile industrial machinery.

The rigid high-impact PVC insulation shroud encloses the conductor on three sides, providing IP21 and IP23 touch-protection for maintenance operators.

Conductor materials feature oxygen-free electrolytic copper (99.9% Cu) or lightweight bimetallic stainless steel-capped aluminum profiles rated from 10 to 1000 A at voltages up to 1000 V, supporting compact straight runways and factory-bent 3D curved track sections with bend radii down to 400 mm.

For compact workshops and automated sorting lines, VAHLE provides multi-pole enclosed conductor systems KBH, KBHT, MKH, and VKS 10.

Inside a single continuous synthetic housing, between 4 and 11 insulated conductors are securely housed, including three-phase power, a distinct green PE ground line, and auxiliary control wires.

Continuous jointless copper strips drawn directly from coils eliminate voltage drops and brush arcing, ensuring uninterrupted power delivery to current collector trolleys traveling at speeds up to 250 m/min.

FABA Heavy-Duty Open Rails and Motorized Festoon Systems for Ports and Foundries

In high-temperature steelworks, foundries, and coastal container ship-to-shore (STS) cranes, VAHLE supplies uninsulated open conductor systems FABA alongside heavy solid copper T-rail and I-beam profiles rated up to 3000 A.

These uninsulated rigid copper bars and copper-clad steel beams are mounted on high-strength ceramic or cycloaliphatic epoxy standoff insulators with extended creepage distances, resisting severe mechanical vibrations from multi-ton ladles, coastal wind loads, and salty marine mist.

To provide flexible power and fiber-optic communication to moving crane hoists and crab trolleys, VAHLE produces an extensive range of heavy-duty festoon systems.

Built on cold-rolled galvanized C-rails (S1, S2, S3), diamond tracks, or heavy rolled steel I-beam flanges, these festoon systems utilize precision ball-bearing cable trolleys with elastomeric clamps that protect flat rubber and round cables from excessive bending fatigue during millions of

operating cycles.

Contactless Wireless Power Transfer vPOWER CPS and APOS Positioning

A pioneering frontier in industrial power delivery is VAHLE vPOWER contactless power supply, powered by proprietary Contactless Power System (CPS) induction technology.

Transmitting up to 40 kW of electrical power across air gaps at 20 kHz and 140 kHz, CPS completely eliminates mechanical friction, carbon wear dust, and electrical arcing.

This wear-free architecture is essential for semiconductor cleanrooms, pharmaceutical automated warehouses, and automated guided vehicles (AGV/AMR), where primary loop cables can be embedded flush into factory floors.

For automated high-bay crane storage and retrieval machines (AS/RS), VAHLE offers the vPOS absolute positioning portfolio featuring APOS Optic and APOS Magnetic technologies. Optical barcode tape or magnetic strips snap directly into pre-engineered channels within VAHLE conductor rail housings.
