Yellow cables are commonly used in various electrical and communication applications. These cables are made of polyvinyl chloride (PVC) material, known for its durability and versatility. PVC wires and cables are popular choices for house wiring due to their ability to safely carry electrical currents. Coaxial cables are another type of cable commonly used for transmitting radio frequency signals. These cables consist of an inner conductor, insulating layer, and an outer conductor. Aluminium twin wires are also used in electrical applications. These wires have two conductors made of aluminum, known for its lightweight and corrosion-resistant properties. Submersible wires are specially designed for use in submerged conditions, such as underwater pumps. These wires are insulated to prevent water damage and ensure safe operation. CCTV cables are used for connecting surveillance cameras to monitoring systems. These cables are designed to transmit video signals over long distances with minimal interference. Coaxial cables are also commonly used for CCTV applications due to their ability to transmit high-quality video signals. In summary, yellow cables encompass a variety of types, each serving specific purposes in electrical and communication systems. PVC wires and cables are popular for house wiring, while coaxial cables are used for transmitting radio frequency signals.
