Safe positioning of electrolytic ground terminal: protecting the foundation from the talik zone

Safe positioning of electrolytic ground terminal: protecting the foundation from the talik zone

The filler of the electrolytic ground terminal contains salts that lower the freezing point of the soil. As a result, a talik zone is formed, where the soil's freezing temperature is lower than it would be under natural conditions.  If the electrode is installed too close to the foundation, the difference in the deformation of the thawed and normal soil can create an uneven impact on the foundation, causing tensile forces. This fact must be considered when designing and installing electrolytic grounding.

New Securing Attachments for ZANDZ Lightning Protection Holders

New Securing Attachments for ZANDZ Lightning Protection Holders

When installing lightning protection, an important issue arises, i.e. how to maintain roof durability and water tightness. Drilling holes in the metal roof and walls to install holders may impair their integrity. Securing a holder using a self-tapping screw does not eliminate the corrosion and leaks at the points where the sheet metal was damaged. Rubber or polymer seals age and dry out due to UV and temperature drops, thus preventing the reliability issue.

We invite you to the webinar

We invite you to the webinar "The danger of extended underground communications in lightning protection."

Any metallic communication is a high-risk element in lightning protection because it can transmit lightning overvoltage over long distances. However, the defining word "underground" is included in the title. Such communication is not alarming, intuitively. There is a false illusion created by the enduring habit of believing that grounded is safe! The webinar will cover all particularly dangerous manifestations of overvoltage transport over such communications, with a focus on the consequences for the human body.
