Installing cables may look like a simple procedure, but there are several factors that installers are considering behind the scenes. Bend radius, tensile rating, cable slack, cable protection and conduit fill utilization are just a few of these considerations.
1. Bend radius
A cable&#;s bend radius may be the most important aspect to keep in mind. Copper cable consists of conductors that are twisted together, so excessive bending or twisting can disrupt the careful geometry of those twists. Bending, twisting or stretching is also damaging to a fiber cable, but for different reasons. The fiber cable will instead be damaged by micro cracks that result in broken fibers or attenuation (the loss of signal strength throughout the cable). Cable manufacturers always provide a minimum bend radius for cables under tension. When you&#;re pulling cables, following the minimum bend radius will ensure no damage is done to the cables and prevent the need for a reinstallation.
2. Tensile rating
Another factor to keep in mind while pulling cables is tensile rating. Like bend radius, tensile rating is specified by the manufacturer and refers to how much tension is allowed to be placed on the cable. Installers using mechanical pulling devices should monitor the tensile rating during installation and ensure the number specified by the manufacturer is not exceeded; otherwise, the cables may be damaged. Long pulls can use certain pull techniques such as backfeeding or center-pull to ease the tension on the cable.
3. Cable slack
It&#;s recommended that installers leave some (20-30 feet) slack cable to reduce labor and hardware costs. If a cable repair or relocation is needed, the slack can be shifted to the damaged point. This slack cable can be stored at planned future cable drop points to allow relocation of terminals to take place without splicing. This small consideration during installation can save a significant amount of time in the future.
4. Cable protection
Installers should consider the integrity of the cables not only during installation but also after. Depending on where a cable is being installed, outside protection may be necessary to keep cables safe, and installers should consider whether a conduit or duct is necessary based on the installation circumstances. Underground installations, for example, almost always require a conduit when cables are installed. One cable per conduit is the standard, except with a product such as Vis&#; Divide, which is a rigid segmented conduit that allows for up to three cables inside one conduit. If future cable pulls are a possibility, Vis Divide also provides an available pathway if all segments are not utilized. Regardless of the application, protecting the cables from physical harm after installation is a must.
5. Conduit fill utilization
Proper conduit fill is imperative for efficient space utilization during cable installations. Conduit fill refers to the amount of a conduit&#;s cross-sectional area that is occupied by cable(s) and is based on the cable&#;s outside diameter (OD) and the conduit&#;s inside diameter (ID). Most conduits require a fill ratio of less than 50 percent and only permit one cable to be pulled per conduit. Vis Divide, however, allows a fill ratio up to 70 percent and can hold up to three cables per conduit. Utilizing all the conduit space and choosing the correct conduit size should always be a consideration, especially when capacity is a factor.
Why Are Cable Installation Contractors Important?
Cable installation Contractors are part of an essential process for creating a continuous path for data transmission in the United States.
Whether it is copper or fiber optic cables, proper installation and maintenance of these cables from a reputable cable installation company is critical for ensuring reliable and efficient communication networks.
Cable Installers play a vital role in the work National OnDemand does for clients and their customers.
In this blog, we will explore the reasons why cable installation is important in the United States.
- Facilitates communication and connectivity:
Cable installation is crucial for creating a robust and reliable communication network that enables people to connect with each other from different parts of the country and beyond. Communication networks are essential for businesses, governments, healthcare facilities, and educational institutions to exchange information and provide essential services. Without proper cable installation, these networks would not be able to function effectively, leading to disrupted communication and connectivity
- Supports the economy:
The United States&#; economy relies heavily on communication networks to connect businesses and customers across the country and around the world. These networks are critical for enabling transactions, collaboration, and information sharing, making them essential for supporting the country&#;s economy. Cable installation is, therefore, vital for ensuring that these networks operate effectively and efficiently, supporting the country&#;s economic growth.
- Enables access to essential services:
Cable installation plays a critical role in enabling access to essential services, including healthcare, education, and emergency services. Reliable and efficient communication networks are essential for healthcare providers to exchange patient information, provide remote consultations, and deliver telemedicine services. Similarly, education institutions rely on communication networks to deliver online classes and support distance learning. Emergency services also depend on communication networks to respond quickly to emergencies and provide timely assistance.
- Enhances national security:
Cable installation is essential for ensuring the country&#;s national security. The United States&#; military, intelligence agencies, and law enforcement agencies rely heavily on communication networks to exchange information and coordinate activities. Any disruption or failure of these networks could have severe consequences, making cable installation critical for enhancing the country&#;s national security.
- Enables innovation and technological advancement:
Cable installation is crucial for supporting innovation and technological advancement in the United States. High-speed internet, mobile networks, and other communication technologies are essential for enabling research and development, promoting entrepreneurship, and driving innovation across various industries. Proper cable installation is, therefore, critical for enabling these technologies to operate at their full potential, supporting the country&#;s technological advancement and competitiveness.
- Supports environmental sustainability:
Cable installation is essential for supporting environmental sustainability efforts in the United States. Fiber optic cables are particularly more environmentally friendly than traditional copper cables because they require less energy to transmit data and have a longer lifespan, reducing the need for frequent replacements. By installing fiber optic cables, communication networks can become more energy-efficient, reducing their carbon footprint, and contributing to environmental sustainability efforts.
Cable installation is essential in keeping Americans connected from coast to coast.
