What Is the Difference Between Copper-Clad and Copper-Bonded Steel?

Posted by Martin Havelka on Sep 4, 2018 8:02:00 AM

When discussing the components in an electrical grounding system, we often hear the terms “copper-clad steel” and “copper-bonded steel” used interchangeably. Though it may seem inconsequential, each term represents a different copper plating process, in which the copper is composite on the steel core.

The Science of a Lightning Strike and How to Safeguard Your Facility with a Lightning Protection System

Posted by Martin Havelka on May 22, 2018 8:02:00 AM

Lightning is a random, yet devastating phenomena. Across the U.S., a lightning strikes on average 25 million times per year and occurs at a rate of 100 flashes per second worldwide. And according to the National Weather Service, the average strike has an average magnitude of nearly 30,000 Amps.

While lightning strikes are unpredictable and no location or facility is immune from the threat of a lightning strike, there are ways to reduce the risk or damage. Reducing the risk of damage from a lightning strike, direct or nearby, with the installation of a lightning protection system is not always a part of new construction projects. However, shouldn’t it be?

With modern urban and provincial development, commercial and residential facilities contain valuable digital electronic equipment used for day-to-day work and entertainment functions, meaning large investments are at risk during thunderstorms. A direct lightning strike delivers damaging energy, which even the most robust electrical devices and systems cannot withstand if protection measures are not correctly taken.

Lightning strikes are unpredictable and random events. There is no technology available that can prevent lightning from striking a structure or guarantee 100% protection. Lightning protection is based on statistical probabilities and the risk tolerance of the property owner.

Continue reading below as we uncover the science of a lightning strike, and how you can reduce the likelihood of damage to your facility from lightning.

How Grounding System Helped Gold Mine Overcome Rocky Soil Conditions

Posted by Martin Havelka on Jun 27, 2017 8:08:00 AM

The Peak Gold Mine, located in New South Wales, Australia, provided gold deposits and copper concentrate throughout the Asian Market from 1896 to 1920.

While the Peak Gold Mine concluded production long before the change of the millennium, production resurfaced at the mine in the mid 2000s, thanks to the discovery of additional gold.

Despite challenging ground conditions, miners at the Peak Gold Mine have uncovered 99,072 ounces of gold, along with 9,070 tons of copper, and have a predicted working life through 2020. 

So how was this massive amount of materials unearthed from a century-old mine? Continue reading to learn how ERICO Ground Enhancement Material (GEM) improved the grounding system and power quality at Peak Gold Mine.
