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.

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.

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.

Lightning protection of a traction substation in the Novosibirsk region

According to RD 34.21.122-87 "Instructions for lightning protection of buildings and structures" (hereinafter RD), the probability of a lightning breakthrough is a parameter characterizing the failure of a lightning rod as a protective device. It equals the number of lightning discharges into the protected structure divided by the total number of lightning discharges into the lightning rod and the protected structure. The standard degrees of reliability are 0.95 and 0.99.

A brief analysis of the requirements of the SP RK 2.04-103-2013 (Code of Regulations of Republic of Kazakhstan 2.04-103-2013) to lightning protection in Kazakhstan

Like many other countries, Kazakhstan has a set of regulations outlining the process and safeguards against lightning strikes. After reviewing it and taking into account our experience using the Russian Federation's comparable standards, we have chosen to share with you some of the features of this document. When studyingSP RK 2.04-103-2013 “Lightning protection device for buildings and structures” it becomes obvious that the document attempts to link together many European standards. The attempt is of great interest, let's take a closer look at it.

An instance of figuring out how to protect an acetone warehouse and filtration pumping station in the Samara area from lightning

As long as it creates the necessary zone of protection, a single lightning arrester (single lightning protection system) can be used to protect many structures on the property from lightning strikes. A free-standing lightning mast that has the necessary height is one of the best kinds of lightning receivers in these situations. The mast is installed into the ground using a concrete foundation. Its design accounts for the environmental loads (temperature, wind, snow, and earthquake) that the mast would encounter while in operation to ensure dependable and reliable service. The Technical Center ZANDZ.com has suggested a lightning receiver of a similar kind to safeguard an item made up of two buildings.
