Energy supply systems for telescopes and antennas
The combination of solid steel construction, precision engineering and sophisticated electronics turn modern telescopes, observatories and antennas into high-tech machines. Telescope manufacturers around the world have been relying on energy chains, cables and complete solutions from igus® for over 20 years. In elevation, azimuth and GIR, they ensure a reliable energy supply for many years.
Advantages of igus® energy chain systems:
- Lightweight plastic chains, 43 % less weight than steel drag chains
- Low friction and low drive force, wear-resistant and low vibration, easy handling on the construction site
- Worldwide service and warranty
- Easy co-operation with experienced telescopic specialists
Elevation/Altitude
The adjustment of the elevation angle in telescopes and antennas is referred to as elevation or altitude. Specifically, this involves aligning mirrors or telescopes at the correct angle. Energy chains are used to guide the cable in vertical movement.
Azimuth
In addition to the vertical angle, rotation in the horizontal plane is the decisive movement in telescopes and antennas. This rotary movement is known as azimuth. Simple rotation systems from igus® enable rotation angles of up to 600°. In this example, two reverse chains are shown on two levels.
Azimuth/GIR
Below the azimuth, in the "belly" of the telescope, all the cables of the system come together. This special pivot point is also known as the azimuth or GIR. Managing the amount of cable safely and reliably here is a major challenge. This is why the energy chain and cables are often distributed over several levels. In this example, there are three levels, each with two chains running into each other.
Other application areas
In addition to altitude, azimuth and GIR, which are among the greatest challenges for energy chains in telescopes, there are also other possible applications. For example, moving cables can also be found in the rotary movement of the usually gigantic domes or in the closing systems of opening flaps. Here, too, our energy chains offer protection and at the same time ensure smooth and easy running.
Engineering projects and special solutions

Success story
Rotation module for telescope in Hawaii
The Gemini Telescope at an altitude of 4200 metres on the Mauna Kea volcano in Hawaii: a reliable energy supply was required for a rotation module with a rotation angle of 540°, which is earthquake-proof and has high UV and ozone resistance. The azimuth was equipped with an e-chain® 640.600/600.400/1800.0. An e-chain® 5050.30.150/1825.0 is used in the mirror, which can be swivelled through 90°.
The e-chain® supplied by us in 1999 is still in use today.
