As Y\u0131lkomer, as a result of our long-standing efforts, the concept of insulated lightning protection systems has gradually begun to be established in our country. However, the insulated lightning protection system that we try to explain within the scope of IEC standards<\/strong> has started to be understood and implemented in our country merely as connecting a medium-voltage cable to a lightning rod system. Unfortunately, over time, every subject in our country turns into a commercial matter, and we consistently move away from technical principles. As Y\u0131lkomer<\/strong> <\/span>, we wanted to explain the insulated lightning air terminal<\/a><\/strong><\/span><\/em> system to you once again. This subject is an extremely important technical matter that directly concerns life and property safety, especially for flammable and explosive areas, and has the capability to eliminate fire risks and electrical system damage.<\/p>\n

First of all, this subject must be addressed as a \u201cSYSTEM\u201d. If lightning air terminals to which the insulated conductor is connected are used on metallic surfaces, they must be insulated. Moreover, the separation distances must have fully insulating properties and must not be less than 1500 mm. The insulated conductor must be mounted internally within the air terminal so that surface contact is eliminated when an impulse occurs. The insulated conductor must be grounded to a metallic surface both inside the air terminal and along the entire route. Fundamentally, the steps can be listed in this manner.<\/p>\n

Use of insulated lightning down conductor<\/p><\/div>\n

Primarily, the kiloampere-based test value of the insulated lightning down conductor is of critical importance. This value, ranging between 150 kA and 200 kA, must have 200 kA withstand capability<\/strong> for explosive environments. The S separation distance<\/span><\/strong> mentioned for lightning down conductors is also valid for insulated down conductors in explosive environments. For this reason, special conductors that ensure the required \u201cS\u201d separation distance are manufactured. Especially in flammable and explosive areas, each manufacturer must specify the \u201cS\u201d distance of the cable. This distance generally appears at the level of 0.75 or 0.50 cm and is of great importance. For magnetic field protection, direct mounting to the wall does not pose a problem. In addition, manufacturers have determined the maximum usable height of the insulated conductor through testing. As practiced in our country, performing unlimited down-conduction on a 100-meter building using insulated conductors is not an appropriate application.<\/p>\n

Insulated conductors should also be used in building and roof applications.<\/p><\/div>\n

As Y\u0131lkomer, we use HVI series products manufactured in Germany. We use two models, Long and Power, in our systems together with the insulated lightning air terminal system. In particular, the HVI Power insulated down conductor system can be described as the safest insulated down conductor system due to its 200 kA withstand capability and EX environment certification. The most important point in these matters is product certification and testability. Manufacturers should emphasize the withstand capacities and ex-proof characteristics of insulated systems in the declarations they publish.<\/p>\n

In conclusion, the Insulated Lightning Protection System requires a design consisting of system components.<\/p>\n<\/blockquote>\n
