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.

How do you correctly design lightning protection for cultural heritage sites?

How do you correctly design lightning protection for cultural heritage sites?

The design of lightning protection comes with extra requirements that must be met because these kinds of structures were typically constructed prior to the development of the Standards and Technical Documentation for Lightning Protection. Preserving the items in the original state is one of these requirements.

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.
