Slip rings applied to Olympic torch sculptures

The 2024 Paris Olympics are fastapproaching, and the world will soon witness a grand opening ceremony. In pastOlympic opening ceremonies, slip ring technology has often been required inhigh-definition camera equipment and stabilization devices, particularly for HDvideo signal slip rings and conductive slip rings used in rotating stages andother equipment. As a professional slip ring manufacturer, JINPAT is closelymonitoring the application of slip ring technology in the new media center andother key venues for the Olympics.

One of the most memorable moments in everyOlympic opening ceremony is the lighting of the torch. For example, at theBeijing Winter Olympics, the torch was installed at the center of a snowflakesculpture, which rotated clockwise, while the snowflake sculpture itself wasmounted on a ribbon-like sculpture that rotated counterclockwise. To ensure thetorch burned continuously for 24 hours at night, a conductive slip ring neededto be installed at the base of the torch sculpture. If the torch did not usehydrogen as fuel, this slip ring also needed to integrate a gas-liquid passageto transmit natural gas, hydrogen, and other combustible gases.

In designing the conductive slip ring,providing two 15A current paths and one grounding path would fully meet thepower supply needs of the sculpture. Without considering backup paths, thisconfiguration was sufficient to ensure the stable power supply of the WinterOlympics torch sculpture. Even if backup paths were added, it would onlyrequire the addition of two more paths with the same current.

The conductive slip ring used in the WinterOlympics torch sculpture was not highly difficult to design and manufacture. Asa leading slip ring manufacturer, JINPAT is fully capable of designing andmanufacturing such products. Moreover, since the gas cylinder in the torchsculpture was cleverly hidden inside the snowflake sculpture, this slip ringdid not need to integrate a gas-liquid passage, thus eliminating the need forprocessing the gas-liquid module during slip ring manufacturing. Consideringthat the sculpture was installed outdoors, the focus of the slip ring designwas on enhancing its protection level to ensure its reliability in variousweather conditions.
