Cables as the Backbone of the Telescope

The twelve telescope antennas are equipped with 131 highly sensitive cables that run from the heart of the telescope to external systems. These cables are an essential part of the telescope's functionality and precision, ensuring the transfer of data and power.

Cable carriers movement on two axes

Two Cable carriers are Cable carriers on each telescope: one for the polar axis and one for the declination axis. These tracks are specially designed to allow the antennas to move smoothly along both axes. This enables them to remain continuously and accurately focused on a single point in space, despite constant rotations and adjustments in position.

Challenges of Space and Rotations

One of the biggest challenges in this project was the limited space inside the telescopes. In addition, the cables had to be able to withstand complex movements along both the polar axis and the declination axis. This required innovative solutions and a careful approach to Cable carriers the cables efficiently through the Cable carriers and on to the telescopes' electrical enclosure.

Electrical House as Central Point

The cables are routed via the Cable carriers the electrical enclosure, which serves as the central point for all electrical connections and control systems of the telescope. This component is essential for the reliable operation of the entire installation.

Customization by Wisman Techniek

The Cable carriers enable the safe and efficient routing of the cable package have been specially developed by Wisman Techniek. These robust solutions combine flexibility and reliability, making them perfectly suited to the complex requirements of the telescopes.

Cable entry systems for sealing and protection

Wisman Techniek supplied high-quality cable entry systems for sealing and routing the cables in the electrical enclosure. These systems provide reliable protection against dust, moisture, and mechanical stress. This contributes to the long service life and optimal performance of the telescopic antennas under challenging conditions.
