Koaksiaalikaapelityyppejä, or coaxial cable types, are electrical cables that consist of a central conductor surrounded by a concentric conducting shield, with the two separated by an insulating layer. They are widely used in various applications due to their ability to carry high-frequency signals with minimal interference. The primary types of coaxial cables are categorized based on their construction and intended use.

The most common type is the RG-6 cable, which is used in home entertainment systems such as cable television and satellite television. It has a copper conductor and a copper braid shield, providing good signal transmission up to 1 GHz. Another popular type is the RG-59, which is often used in video surveillance systems and has a similar construction to RG-6 but with a slightly different impedance.

For higher frequency applications, RG-58 and RG-58A cables are used. These cables have a solid copper conductor and a copper braid shield, offering better performance up to 4 GHz. They are commonly used in professional video and audio equipment.

For very high-frequency applications, such as in microwave systems, RG-316 and RG-317 cables are used. These cables have a copper conductor and a copper braid shield, with a thicker insulation layer to handle higher frequencies. They are capable of transmitting signals up to 18 GHz.

In summary, coaxial cables come in various types, each designed for specific applications based on frequency requirements and signal integrity. Understanding the different types and their characteristics is crucial for selecting the appropriate cable for a given application.
