koaxkabel

Koaxkabel, also known as coaxial cable, is a type of electrical cable consisting of a central conductor surrounded by a tubular insulating layer, which is then enclosed by a metallic shield and an outer protective jacket. This construction design allows the cable to transmit high-frequency electrical signals with minimal interference and signal loss.

The core component of a coaxial cable is typically made of copper or aluminum, serving as the conductor responsible for transmitting information. Surrounding this core is an insulating material, commonly polyethylene or foam, which prevents contact with the shield and maintains signal integrity. The metallic shield, often braided copper or aluminum foil, serves to block external electromagnetic interference, ensuring cleaner signal transmission. The outer jacket provides environmental protection and durability, safeguarding the internal layers from mechanical damage, moisture, and UV exposure.

Coaxial cables are widely used in telecommunications, cable television distribution, internet connections, and radio frequency applications. Their design makes them suitable for transmitting signals over long distances with reduced attenuation and minimal crosstalk, which is interference from neighboring cables or signals.

Various types of coaxial cables exist, differing in insulation material, shielding quality, and connector types, to suit specific needs and standards. Common connectors include F-type, BNC, and RCA, each designed for different applications.

Overall, coaxial cable’s robust construction and shielding capabilities make it a reliable medium for transmitting high-frequency signals in both commercial and residential settings. Its design continues to evolve with advancements in materials and shielding technology to meet increasing demands for bandwidth and signal integrity.
