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.

New extended zandz interception rods

New extended zandz interception rods

Sometimes conventional interception rods are insufficient. In this case, they may be extended by only several dozen centimeters to increase the reliability of the lightning protection. This extension may be required, e.g. to compensate for the interception rod's height fluctuations due to flat roof sloping.

Specifics of Lightning Protection of Treatment Facilities

Specifics of Lightning Protection of Treatment Facilities

Treatment facilities are a critical set of devices and structures for treating water to the parameters established in regulatory documents and sanitary requirements. The set of facilities usually includes devices for mechanical, biological, and physical/chemical treatment of sewage water. Passing through the treatment facilities, industrial and urban sewage water is separated from mineral, organic, radioactive, and other harmful substances. After this treatment, water is direct to the urban drainage system for additional treatment, drained into the environment, or used for technical purpose.

Why do you need conductor holders on a flat roof?

Why do you need conductor holders on a flat roof?

It is unsophisticated to install conductors on a flat roof. However, there are some nuances in the lightning protection. When building lightning protection systems at the facilities with flat roofs, conductors should be installed in special holders. Such installation ensures both correct conductor positioning and greatly improves its service life.

What is the issue with active lightning arresters? Professor E.M. Bazelian explains

For decades, experts have debated the viability of active lightning protection. It is quite clear that to improve the protective effect of the lightning arrester, it is necessary either to increase the electrical strength of the air along the path of the lightning to the object, or to reduce it on the way to the arrester.

Why is a compensator necessary for lightning protection?

Why is a compensator necessary for lightning protection?

Lightning protection is a system that is operated in fairly harsh conditions. The components on the roof that defend against lightning may easily reach 70 degrees or more in the summer, while negative thirty degrees is quite common in the winter. The thermal expansion effect of metals becomes evident within a temperature range of 100 degrees Celsius. Such a significant temperature change can cause an increase when hot and a decrease when cold in the running length of the lightning grid's or current collector's conductor. Temperature fluctuations will be approximately 11-12 cm for every 100 meters of zinc-plated or copper-plated steel conductor. This increases the possibility of harm to the roofing's firmly fixed lightning protection equipment.
