Coaxial Cables

Coaxial cables are used in data communication including audio/video transmission and more commonly identified with cable TV, computer network (Ethernet) and broadband services. A coaxial cable has an inner copper wire surrounded by a tubular dielectric insulating layer, with a woven metal shield around it and an outer insulating sheath. These cables are different from other cables due to extra metal shield which ensures less signal interference and provides constant conductor spacing for efficient transmission, and that is the one big reason why these cables are used in high frequency audio/video signals.

Types of Coaxial Cable

There are different types of coaxial cables for residential and commercial uses. Following are the 5 main types of coaxial cables:

Hard Line Coaxial Cable

This type of cable is used to carry high strength signals and it measures up to 1/2 inch in thickness.

RG-6 Coaxial Cable

There are more common types of coaxial cables owing to their use in relaying cable TV and other signals. Here RG stands for “radio guide” in reference to the capacity of signals that these cables carry. They may come in various varieties with some having extra waterproofing quality for underwater/moist prone installations.

Semi-Rigid Coaxial Cable

These cables come with little harder shielding metal which makes them less flexible in comparison. They are particularly used in situations where cables don’t bend much.

Tri-axial Cable

This type of cable has an additional layer of shield to reduce electromagnetic interference and is used in places where there is a high-strength electromagnetic field. The additional shield prevents interference to ensure good quality signals.

Twin-Axial Cable

These are paired cables and come as an alternative to conventional coaxial cables where you are provided with more installations options. The above mentioned coaxial cables provide information for choosing the right kind of coaxial cable for installations at home, businesses or other settings.

Some of the more common types of cables available in the market include Co-Axial Cable, Co Axial Cable, Unarmoured Co-Axial Cable, Co-Axial Cables, Armoured Co-Axial Cable, Co-Axial Cables RG 11 (Foam), Co-Axial Cables RG 59 (Foam). Co-Axial Cables RG 6 (Foam) etc. They come in various lengths, conductor types (copper, aluminium, steel etc.) and screen or shield- braided or foiled.

Uses of Coaxial Cables

These cables are used to carry radio frequency signals and owing to their property of providing protection against electromagnetic forces they are used widely in various situations and settings. Their applications include cable TV, computer network (internet/broadband), digital audio, video gaming, ham radio, CCTVs, and undersea cables.
