- T-SL series/18GHZ
- 【Brief】：It is a lightweight radio frequency stabilized coaxial cable specially designed for aerospace. It has the characteristics of light weight, excellent radiation resistance, and stable electrical performance. In terms of mechanical properties, this series of cables are light in weight (15% to 25% less weight than copper cables with the same specifications) and have good flexibility, mechanical phase stability and temperature phase stability. In terms of electrical performance, the signal transmission rate is 83%, and it also has the characteristics of low loss, low standing wave, and high shielding efficiency. In terms of environmental resistance, the cable uses raw materials with excellent environmental resistance, so that it has good radiation resistance (irradiation dose up to 10KGy), as well as a wide operating temperature range, corrosion resistance, mildew resistance, moisture resistance, flame retardancy, etc.
1. Inner conductor: a single silver-plated copper wire.
2. Insulation: PTFE is adopted, and the transmission rate is 83%.
3. Shielding layer: Two shielding layer structure is adopted, the inner shielding layer
is wrapped with silver-plated copper tape, and the outer shielding is braided with metal composite conductors.
4. Sheath: ETFE sheath is used.
