Riser Cable: Understanding and Installation

Do you ever ask yourself how the internet service provider functions in tall buildings? There is one specific thing: riser cable. 

Riser cables are special wires used for vertical installations between different floors of multistory buildings. 

These cables are very important in connecting to the internet, telephone, and other data services. 

 It appears to be very complicated to understand the riser cables and even how to install them, but in real essence, it isn’t. 

In this blog, we will cover what the riser cable is, its application, installation methods, and the difference between the riser cable and the plenum cable. 

After understanding these cables, you will understand why they are important and their significant role in ensuring the operation of more modern structures and infrastructure.

What is Riser Cable and Where to Use It?

A riser cable is an electrical cable that is used to run vertically between the floors in the building in question. 

Sometimes, it is installed in the shafts or spaces known as risers that are between various floors. These cables are fundamental since they are designed to minimize fire outbreaks between floors and also have a flame-resistant jacket. 

Most riser cables are located in the walls of office complexes, hotels, or high rise apartments. They are used to link up telecommunication devices, including phones and internet equipment, from one floor to the next. This is why the use of riser cables in those situations is recommended for safety and compliance with building regulations. 

Therefore, a riser cable is the best choice if you need to install a network in a multi-story building.

Where can I use non-rated cables?

These cables are not tested to meet certain safety levels but can be utilized in areas where the risk of physical harm or fire is almost impossible. 

These include temporary connections such as short-term events, minor home renovations or projects, or for general, non-essential purposes. 

For instance, non-rated cables may be adequate if you plan to install a temporary sound system for a backyard party.

They are also ideal for experimentation or pilot projects in restricted conditions where risks for individuals are not a factor. 

Customers should always ensure their use does not breach any of the local electrical codes or safety standards.

What is Plenum Cable?

These cables are not tested to meet certain safety levels but can be utilized in areas where the risk of physical harm or fire is almost impossible. 

These include temporary connections such as short-term events, minor home renovations or projects, or for general, non-essential purposes. 

For instance, non-rated cables may be adequate if you plan to install a temporary sound system for a backyard party. 

They are also ideal for experimentation or pilot projects in restricted conditions where risks for individuals are not a factor. 

 However, they should not be used in permanent installations, busy areas, or where cable failure could lead to dangerous conditions. 

Customers should always ensure their use does not breach any of the local electrical codes or safety standards.

When to Use Plenum Cables?

Plenum cable is a type of electrical cable most suitable for use above the ceiling or beneath the floor, the areas referred to as plenums where the flow of air is generally experienced.

These cables have an outer jacket that increases their fire rating, which also means that they will emit less toxic smoke than conventional cables if they burn.

This makes them safer for use in buildings because the plenum spaces that are found in the construction of the building can contain smoke and flames. 

Normal cables can be risky in such zones, and that is why cables designed for plenum aid in the conservation of the structure and the people inside it. 

It is used for telephone, networking, and other electrical wiring requirements that are common in spaces such as offices and businesses.
