Cables by Type

Coaxial Cable

Coaxial cables, or coax cables, are a type of electrical cable that transmits high-frequency signals with low interference and signal loss. These cables are widely used in telecommunications, internet, and cable television industries due to their superior shielding and transmission capabilities. Coaxial cables are constructed with a central conductor, an insulating layer, a metallic shield, and an outer insulating layer, which work together to protect the signal from external electromagnetic interference (EMI).

Coaxial cables are renowned for their ability to efficiently transmit high-frequency signals with minimal loss, ensuring clear and stable data transfer over considerable distances. Their superior shielding against electromagnetic interference (EMI) makes them ideal for environments where signal purity is critical. These cables are built to last, boasting durable and reliable construction that withstands various environmental conditions. Their versatility is unmatched, finding applications across telecommunications, internet infrastructure, and the TV industry, where they form the backbone of modern communication and entertainment systems.

Coaxial cables can be classified into various types, with RG (Radio Guide) coaxial cables and hardline coaxial cables being two of the most common categories.

RG Coaxial Cables

RG coaxial cables are named based on the Radio Guide specifications developed by the U.S. military. These cables are widely used in residential and commercial applications, particularly for video and data transmission.

Construction:

● Center Conductor: Typically made of copper or copper-clad steel.

● Dielectric Insulator: UMade of materials such as polyethylene (PE) or foam PE.

● Shielding: Consists of one or more layers of braided copper, aluminum, or foil.

● Outer Jacket: Made of PVC, PE, or other materials for environmental protection.

Common Types:

● RG-6: Used for cable television, satellite TV, and internet.

● RG-59: Used for CCTV, video, and low-frequency applications.

● RG-11: Used for long-distance signal transmission and high-bandwidth applications.

Hardline Coaxial Cables

Hardline coaxial cables are designed for high-power signal transmission and are commonly used in professional and industrial applications, including cable television distribution networks and radio transmitters.

Construction:

● Center Conductor: Typically made of solid or tubular copper or aluminum.

● Dielectric Insulator: Often made of polyethylene (PE) or a similar material.

● Shielding: Consists of a rigid outer conductor, which can be a solid aluminum or copper tube.

● Outer Jacket: Made of durable materials such as PE or PVC to withstand environmental conditions.
