Coaxial cable, often referred to as coax, is a type of electrical cable that consists of a central conductor surrounded by an insulating layer, a metallic shield, and an outer insulation layer. It is designed to transmit high-frequency signals with minimal interference and attenuation.

Key components of Coaxial Cable:

1. Inner Conductor: Usually made of copper or aluminum, this wire carries the electrical signal.

2. Insulator: A dielectric material surrounds the inner conductor, maintaining a gap between the conductor and the shield.

3. Outer Shield: Typically made of braided copper or aluminum, this layer protects against electromagnetic interference (EMI) and helps to prevent signal loss.

4. Outer Jacket: The durable plastic or rubber sheath that protects the inner components from environmental damage.

Common Uses:

• Cable television distribution

• Internet connectivity (e.g., broadband)

• Radio frequency transmission

• Video and audio applications

Coaxial cables are popular due to their ability to efficiently carry signals over long distances while minimizing noise and interference.
