Triaxial cables were developed primarily to reduce noise levels in systems along with providing an isolated ground.
Used extensively in Medical applications such as Radiation Detection and Dosimetry as well as Broadcast applications, Triaxial (or Triax) cable provides greater bandwidth and interference protection than Coaxial cable.
Intelliconnect predominantly use 3 types of Triaxial Cable: RG403, Belden 9222 and Huber Suhner G02330HT.
