When installing cables outdoors, there are three main installation types: direct burial, aerial, and underground. Each type of installation has its benefits and drawbacks, so it’s essential to choose the right one for your needs. But not all cables that are outdoor-rated can be buried underground. So let’s now take a closer look at these outdoor cables, their differences, and how they can be used in outdoor applications.
1. Aerial installation
Aerial installation involves installing cables and other equipment on utility poles or other structures using helicopters or other aircraft. This type of installation is typically used for high-voltage power lines, communication towers, and other large structures.
Aerial installation is a specialized type of work that requires specific training and equipment. Helicopters are equipped with long lines that are used to lift the cables and equipment into place. The pilots must be highly skilled to navigate the aircraft while avoiding obstacles.
Once the cables and equipment are in place, they must be properly secured to prevent them from falling or being damaged by wind or weather. Aerial installation is a challenging but rewarding career offering a unique worldview.
2. Direct burial installation
Direct burial installation is a method of installing underground cables. This type of installation is typically used for communications or electrical cables. The process involves trenching, laying the cable in the trench, and then backfilling the trench.
Direct burial installation is more labor-intensive than other methods, but it has several advantages. For example, it is more durable and resistant to damage, and it can be used in areas where other methods are not possible.
As a result, direct burial installation is often the best choice for applications that require long-term reliability.
3. Underground installation
Installing cable underground can be a challenging but rewarding process. It begins with excavating a trench for the cable to be laid in. The trench must be wide enough and deep enough to accommodate the cable, as well as any other materials that will be used to protect it.
Once the trench is excavated, the cable can be installed. Depending on the type of cable being used, this may involve special methods or equipment. Once the cable is in place, it must be covered with a layer of protective material to shield it from the elements.
Finally, the trench is filled in and compacted, leaving the cable safe and hidden underground. Installing cable underground can be time-consuming and complex, but it results in a much more durable and long-lasting installation.
How do you determine which type is best for your needs?
When it comes to cable installation, there are two main options: indoor and outdoor. Both have advantages and disadvantages, so selecting the option that best meets your needs is essential. For example, indoor cable installation is typically more expensive than outdoor installation but offers excellent protection from the elements.
On the other hand, outdoor installation is less costly and easier to install, but it is more vulnerable to weather damage. Therefore, when choosing a type of cable installation, it is essential to consider your budget and your needs in terms of protection and durability.
