What is Triable Cable?

 

Triaxial Cables are usually RG58A/U, RG59/U, RG11/U, and are also used as Belden's 9272 and 9222 cables, and also used as Microdot's 293-3930 cables.

The second layer of shielding makes The outer diameter increases, so size and flexibility will be a problem.

RG-11 has lower loss during long-distance transmission, while RG-59 has a smaller appearance and better flexibility.

Triaxial Cables are typically used for internal connections between cameras and related equipment. In use, the quality requirements for Triaxial Cables are mainly flexibility and flex life. Typical products are Belden 9267 and 9232 products with Hypalona sheath. The products have changed from traditional solid central conductors to multi-stranded conductors. The stranded center conductor to increase the flexibility of the cable.

Typical product indicators of Triaxial Cables are as follows:

1. 8232 (Belden), RG-59/U, video Triaxial Cable, smaller in size than RG-11/U, good flexibility: 20AWG solid bare copper conductor, foamed polyethylene insulation.

2.  2 layers of bare copper braided mesh shield , 95% shielding coverage, polyethylene insulation between shielding layers, polyethylene sheath, 100% sweep test frequency bandwidth 5-300MHz.

Rated outer diameter (mm) Insulation thickness (mm) Sheath thickness (mm) Rated capacitance (pF/m) Rated conductor DC resistance (Ω/km) Propagation speed NVP (%) Characteristic impedance (ohms) 12.07 2.743 10.414 52.787 8.197 84.0 75.0 At present, the radio frequency Triaxial Cables and connectors for data buses have been widely used in surface ships, aviation and many commercial fields, such as telemetry, radar, satellite signal transmission, data networks, airports, armored forces, and agencies' surrounding guards, etc. Occasionally, it is also widely used in digital data trunks, video pairs, baseband circuits and other noise-free advanced protection circuits. Because they can improve the transmission capacity and anti-interference ability of data transmission systems, Triaxial Cables and connectors are widely used for the transmission and measurement of weak signals such as low thermoelectric potential EMF and signals with high shielding requirements.
