High-altitude scientific balloons and airships used in near-spacemissions often carry scientific payloads requiring slip rings for theiroperations. Near-space aerostats, particularly heavy-load aerostats, may beequipped with various electrical slip rings, such as those for attitude controlsystems or those needed by observation or testing equipment in the payload.

In slip ring solutions previously provided by JINPAT, many modelsare capable of operating reliably in the extremely low-temperature environmentof near space. Among these, JINPAT frequently integrates SDI high-definitionsignal slip rings, primarily using multi-channel capsule and small hollow-shaftslip rings, all of which are custom-designed.

One notable product is a large-sized multi-functional integratedslip ring with a total length of 1447 mm and a maximum diameter of 390 mm. Thisproduct, developed specifically to meet the GJB technical standards fornear-space environments, features a high level of integration. Its model numberis LPT000-02200-08180-1060-2110-2701-22S-FO02-HF02, and it integrates ahigh-power module (voltage: 270 VAC), low-power signal module, optical signalmodule, and radio frequency (RF) signal module. The optical signal module usesa 2-channel multimode fiber optic slip ring, while the RF signal moduleoperates at frequencies of 1.2–1.65 GHz. Notably, this RF module employsstandard slip ring wiring methods rather than specialized high-frequency rotaryjoints.

Despite its large size and multi-functionality, the slip ringachieves a protection rating of IP65. To ensure reliability, it features a speciallydesigned structure with individual physical isolation between modules,providing strong anti-interference capabilities. This enables the integratedslip ring to withstand vibration and shock, while also meeting EMC(electromagnetic compatibility) requirements.

In addition to such large, multi-module integrated slip rings, JINPAToffers a wide range of small integrated electrical slip rings. These productsare primarily used in scientific high-altitude and near-space balloons andairships, with integrated functions varying according to applicationrequirements.
