Plenum, (pronounced PLEH-nuhm),refers to a specific area within a building, primarily used for air circulation. This space is commonly located between the building's roof and a drop-down ceiling or, in some cases, beneath the floor. Its main purpose is to accommodate HVAC (Heating, Ventilation, and Air Conditioning) systems, functioning similarly to the lungs of a building. TheHVAC equipment in the plenum space is responsible for drawing air in through vents and distributing it back into the building through ducts.
The plenum space, however, is not limited to housing only HVAC equipment. It is increasingly being utilized for other purposes, such as routing communications cables, including networking cables. This versatile use of plenum space is a response to the evolving infrastructure needs of modern buildings, where efficient space utilization
is crucial. The plenum thus plays a dual role in both maintaining a building's climate control and supporting its communication and network systems.
Plenum cables are specially designed for use in a building's plenum spaces, which are crucial for air circulation. These cables are made to be fireresistant and emit less smoke in case of a fire. This is important because maintaining air quality and reducing fire hazards in plenum spaces are critical for building safety. Plenum cables must meet strict
safety standards to ensure they are suitable for these sensitive areas.
Plenum coaxial cables are specially designed for installation in plenum spaces of buildings, which are areas used for air circulation for heating, ventilation, and air conditioning systems. These cables are made with fire-retardant materials to meet strict building code requirements. The three common types of plenum coaxial cables are RG6, RG59, and RG11, each with distinct characteristics:
RG6 Plenum Coaxial Cable:
Ideal for digital TV, cable TV, satellite installations, and high-speed internet. It features a thicker conductor and better shielding, suitable for longer distances and higher
frequencies, with a fire-retardant jacket.
RG59 Plenum Coaxial Cable:
Commonly used for CCTV and analog video over shorter distances. It's more flexible than RG6, easing installation in tight spaces, and also has a fire-retardant jacket for
plenum safety.
RG11 Plenum Coaxial Cable:
Best for long-distance signal transmission in large buildings or extensive installations. It has a larger gauge for lower signal loss over long runs and is built with fire-resistant,
low-smoke materials for plenum use.
