3 Lightning-Related Problems for Telecommunication Towers in Very Dense Cities

Posted by Rohit Narayan on Apr 16, 2019 8:00:00 AM

This following is part of our telecom lightning protection series, which is based on our whitepaper “Earth Potential Rise in Public Spaces Near Telecommunications Facilities,” that presented at Intelec 2018.This paper is copyright of IEEE You can download the full whitepaper here.

Traditionally, telecommunication networks were housed in secure structures or locations, keeping them at an adequate distance from very dense populations.

Today, network densification is used to provide high data speeds. Some of the infrastructure—small cells, macro cells, street cabinets—will be located in densely populated metropolitan areas.

Lightning strikes to telecom facilities in these densely populated locations can cause headaches and costs for facility owners, including:

  • Dissatisfaction about the carrier from nearby network users
  • Concerns about personnel injury during lightning strikes
  • Costs, at times in the form of large compensations to neighbors

Historically, lightning protection and earthing system requirements for telecommunications facilities has been focused on protecting the facility and equipment.

While this method works for most facilities, in densely populated cities, attention must also be given to properties located close to the radio tower. The existing standards and design methods do not fully consider the effects a lightning strike to the tower may have on these nearby structures.

In this post, we assess the three problems this creates, and provide general solutions to those complications.

Combat Copper Theft: How to Protect Your Investment

Posted by Rohit Narayan on Mar 27, 2018 8:03:00 AM

Copper is viewed as the global standard for electrical conductivity in the utility sector. It’s high current carrying capacity coupled with its resistance to scratches and breakage, and its resilience to corrosion makes it a universal metal for many applications.

As international construction booms and copper demand rises with it, we’re faced with a startling reality: copper theft costs U.S. businesses nearly $1 billion in losses annually.

There’s no sign of slowing in the global construction sector, and that means the threat of copper theft is greater than ever before. Read on to learn the issues surrounding copper theft and how to prevent it from happening to your business.

The Six Point Plan to Achieving Telecom Facility Lightning Protection

Posted by Rohit Narayan on Mar 13, 2018 8:01:00 AM

Lightning is a constant risk. A single direct strike can result in physical damage to buildings and cause catastrophic failure of sensitive electronic equipment. Lightning causes 22,600 fires per year and is the number one natural cause of system failures. As a result, these problems can result in substantial revenue losses.

Telecommunications facilities are particularly at risk of direct lightning strikes—and the electrical surges that ensue—due to their tall stature and complex electrical makeup. 

However, there is a way for engineers to protect telecommunication facilities from the devastating and lasting effects of lightning damage. 

According to Above Ground Level Magazine, engineers can help protect telecom facilities from the dangers associated with lightning strikes using a six point plan of protection. Continue reading below to learn more about these six steps of lightning protection for telecom facilities.

3 Reasons Engineers Should Choose Copper-Bonded Ground Rods

Posted by Rohit Narayan on Jan 16, 2018 8:04:00 AM

Picture yourself driving your car on the highway when all the of the sudden you see brake lights and are forced to slow down because of construction. As you come to a stop, you see workers repaving a damaged road. Now, cars begin to line up in front of you and behind you. Where do you go? Nowhere—you’re stuck.

A ground rod, also known as an electrode, is similar to this highway scenario. It acts as the only electrical path to dissipate static discharge voltage (such as lightning) into the earth. When that path starts to break down, the static discharge has nowhere to go and puts the whole system at risk.

Many times, engineers are given the choice between three types of ground rods: copper-bonded steel, copper clad ground rods or galvanized steel for grounding systems. However, one material reigns supreme when it comes to strength, service life and overall investment. Hint: it’s copper bonded steel. 

Continue reading below to learn why copper is the better choice for grounding systems versus it’s steel alternative.

3 Ways the New Alliance of Telecommunications Industry Solutions Guidelines Deter Copper Theft

Posted by Rohit Narayan on Oct 17, 2017 8:06:00 AM

Copper has been the most widely used material in telecommunication wiring due to its conductivity , relatively low cost and reliability and corrosion resistance in a wide range of soils. Though, with copper theft on the rise, the industry is looking for alternatives to both deter thieves and lessen the risk of hazards like facility downtime or personnel injury.

The Alliance of Telecommunications Industry Solutions (ATIS) has released an updated guideline on copper alternatives. This new guideline, ATIS-0600037: Testing Guidelines for Copper Theft Deterrents in the Telecom Industry, provides information and recommendations on the use of alternative materials in both above and below grade grounding systems.

Read below to learn key recommendations from the new ATIS guideline to help deter copper thieves at your telecommunication facility.
