Today, more than ever, successful theatrical performances feature dynamic interplay between stage components. Parts that are raised, lowered, or directed need the right energy and data transmission technologies. Moveable stage lighting battens and lighted acoustic panels require power and control signals to the moving parts. Cables for moving audio systems must be managed. Scenery wagons require electrical supply to junction boxes and interlocks. Control signals and data bus signals are needed for stage lifts. Mobile media towers in the wings require energy supply and control for spotlights, transmission of audio signals, and other necessary energy and data transfer. Electrical power, audio, video, and data bus signals must be supplied to revolving stages or rotating props. Everything must run flawlessly or the show can’t go on!
When you need the optimum solution for your moving stage and theater applications, call Conductix-Wampfler. With more than 50 years of experience and installations all over the world, we provide the stage technology that makes it all run, both over stage and for under-stage machinery. Conductix-Wampfler goes beyond just the supply of products. We offer competent advice on the selection of the optimum cables and accessories and project planning to include comprehensive logistical concepts and on-site commissioning.
Spring-driven and Motor-driven Cable Reels – manage silently and automatically lighting power cables, DMX cables, and Ethernet cables as light battens move.
Cable Festoon System – can be used alone or with spring-driven cable reels to create highly flexible moving systems.
Energy Guiding Chains – manage multiple power and data cables in a single chain to power and control stage lifts. Cable Chains are used in a zig-zag pattern as alternative to cable reels, or an alternative to festoons for linear motion.
Inductive Power Transfer (IPT®) – powers stage wagons contactless in a way that is completely hidden from the audience. IPT® can be used in curved applications to transfer power to revolving stages also!
Conductor Rails – supply energy and data to mobile lighting, speaker and media towers in the wings. Multiple towers can run from the same conductor rail system. Curved conductor rails can be used to transfer power and data to rotating stages.
Slip Ring Assemblies – transmit continually power and data signals such as DMX, Ethernet, Profibus, CAN bus into revolving stages or stage props.

Generally the basic function of Floor systems is the same as that of other Inductive Power Transfer systems. But there are some additional or specific aspects to consider.
The cable loop must be installed in a way that complete coverage of the supply of vehicles along the entire travelling path is given. This way installed the cable routing also defines the travelling path of vehicles. With inductive track guidance it is possible to detect the magnetic field around the cabling and to supply a guidance signal to the vehicle control and to control so the movement of the vehicle. Unwanted and expensive guidance slots become obsolete this way. Various travelling paths can be defined. Switches, crossings, etc. are no problem. The pickup just needs to be placed so that it is exposed to the magnetic field in a sufficient way.
