In the world of overhead power lines, two commonly used types of cables are Figure 8 and All-Dielectric Self-Supporting (ADSS) cables. While both serve the same purpose of transmitting electricity, they differ in their design, construction, and installation. Understanding the differences between Figure 8 and ADSS cables can help in choosing the right option for a specific application.
**Figure 8 Cables**.
Figure 8 cables are named for their characteristic shape, which resembles the number 8 when viewed from the side. These cables consist of a central core surrounded by one or more layers of conductors, typically made of aluminum or aluminum-clad steel. The conductors are supported by a series of spacers arranged in a figure-eight pattern, which provide the necessary mechanical strength to withstand the tension placed on the cable.
One of the key advantages of Figure 8 cables is their high tensile strength, which allows them to be installed over long spans without the need for additional support structures. This makes them ideal for use in rural areas or locations where space is limited. Figure 8 cables are also relatively easy to install and maintain, as they can be strung between poles or towers using standard installation practices.
**ADSS Cables**.
ADSS cables, on the other hand, are designed for use in environments where traditional cables may be at risk of damage from environmental factors such as wind, ice, or salt. Unlike Figure 8 cables, ADSS cables do not require a separate support structure, as they are designed to be self-supporting. This is achieved through the use of a central aramid yarn or fiberglass rod that provides the necessary strength to withstand the tension placed on the cable.
One of the primary benefits of ADSS cables is their resistance to electrical interference and lightning strikes. Because they are made entirely of dielectric materials, ADSS cables do not conduct electricity and are therefore less susceptible to damage from electrical faults. This makes them a popular choice for use in areas with high levels of electromagnetic interference or where a high degree of reliability is required.
**Differences Between Figure 8 and ADSS Cables**.
The main difference between Figure 8 and ADSS cables lies in their construction and installation. Figure 8 cables require additional support structures, such as poles or towers, to maintain their tension and prevent sagging over long spans. In contrast, ADSS cables are designed to be self-supporting and do not require any additional structures for installation.
Another key difference is in their susceptibility to environmental factors. Figure 8 cables are more vulnerable to damage from wind, ice, and other external forces due to their reliance on external support structures. ADSS cables, on the other hand, are designed to be resilient to these factors and can be installed in a wider range of environments.
In conclusion, while both Figure 8 and ADSS cables serve the same basic purpose of transmitting electricity, they differ in their design, construction, and installation requirements. Choosing the right type of cable depends on factors such as the location, environmental conditions, and required level of reliability. By understanding the differences between Figure 8 and ADSS cables, it is possible to make an informed decision based on the specific needs of a given application.
