What is cable triaxial?

Cable triaxial is a type of coaxial cable which has three layers of shielding instead of one or two in a regular coaxial cable. The inner layer is the central conductor, which is surrounded by a dielectric insulator, then a mesh shield, and finally an outer conductor, which provides an additional layer of protection against electromagnetic interference (EMI) and radio-frequency interference (RFI).

Triaxial cables are commonly used in applications where a high level of signal integrity is required, such as in the broadcast industry or in medical equipment. They are also used in aerospace and defense applications, where reliability and robustness are a critical factor.

One of the main advantages of a triaxial cable is its improved signal-to-noise ratio, which results in better overall transmission quality. Another advantage is that it provides higher levels of isolation from external interference, resulting in less signal distortion and better signal accuracy.

However, triaxial cables are generally more expensive than regular coaxial cables due to their additional shielding layers. They also tend to be bulkier and heavier, making them less suitable for certain applications where space and weight are a concern.
