e-spool® Standard and HD Options

With the e-spool® standard and HD options, cables are wound up in an energy chain in a space-saving way. By using the twisterband, a wide variety of media can be guided without interruption. This means that adjustments and extensions of the filling system can also be made at any time.

Flexible energy supply - routing of all media in one system
Can be used in a variety of ways - energy supply possible in all directions
Cost-effective - twisterband allows rotary movement
Space-saving - energy chain retracts into a compact unit
No tensile strain on the cables
Cables can be added or changed at a later date
iF Product Design Award 2013

Filling guidelines for the e-spool® cable reel

Due to the special mechanical stress in an e-spool®, we recommend using our chainflex® cable. We also recommend adhering to the following filling rules:

Cables must be routed side by side within the linear chain, never stacked on top of one another.
Wherever possible, use unshielded chainflex® cables with a TPE outer jacket.
For shielded applications, use cables from the chainflex® CFROBOT series.
Always adhere to the maximum bend radius specified for the twisterband.
Use separators where possible to protect cables from flashover and abrasion. For optimal use of internal space, install separators alternately in consecutive segments.
Arrange cables by diameter or bend radius: place smaller, more flexible cables toward the inside and larger ones toward the outside.
Ensure strain relief at both ends of each cable. Cable tie knots must not be positioned in the direction of the chain.
Cables should be installed in the twisterband with sufficient clearance both inward and outward relative to the rotary axis.

Installation Instructions

For horizontally moving applications, ensure a smooth and even surface is provided for the energy chain to travel on.

e-spool® stage equipment

In the theatre and stage industry, space constraints behind the scenes can cause problems for designers and engineers, so products such as the igus® e-spool® and zig zag chains are ideal for such applications which require stage cable management.
The e-spool® is a cable reel system but works without a slip ring. This drum allows different cable types to be safely guided together. Since most reels can only carry one cable this can drastically reduce the number of units (and therefore space and cost) required.

e-spool® flexible cables in stage technology

Failure of stage technology, such as the cables and cable reels, is not an option. “The show must go on,” as they say. And more importantly, the safety of the actors and audience depends on reliable and fail-safe technology.

Frequently asked questions regarding e-spool®

When many different cables should be routed in very confined spaces. Different media (power, air and fluids) can be routed together in one system.

In view of the special mechanical stress inside an e-spool, we recommend using igus chainflex cables. We also recommend that the following guidelines are observed:

Where possible, cables with a TPE outer jacket should be used for unshielded cables.
Shielded cables should be chosen from the CFROBOT range.
All cables should have an outer diameter of < 17mm.
The maximum bend radii of 44mm in the inner radius and 77mm in the outer radius are observed.
