Description
External lightning protection represents the system providing interception of a lightning and branch it to the earth, thereby, protecting the building (construction) from damage and the fire. At the time of a direct stroke of a lightning in construction object correctly designed and built lightning protection device has to assume current of a lightning and take away it on conductor cables vsisty grounding, where energy of the category has to dissipate safely. Passing of current of a lightning has to happen without prejudice to the protected object and to be safe for the people who are as inside, and outside of this object.

There are following types of external lightning protection:

  • molniyepriyemny network;
  • the tense molniyepriyemny cable;
  • molniyepriyemny core.

Besides the above-mentioned traditional decisions (provided both in the MEK 62305.4 international standard, and in the Russian normative documents of RD 34.21.122-87 and CO 153 — 343.21.122-2003) from the middle 2000kh years the lightning protection with system of early streamer issue which is also called by active lightning protection gains distribution. Use of this system is normalized by several standards, first of all the French NFC 17-102.

Generally external lightning protection consists of the following elements:

  • The lightning rod (the interception rod, the lightning rod) — the device intercepting a lightning discharge. It is made of metal (stainless or galvanized steel, aluminum, copper)
  • Conductor cables (descents) — the part of the lightning rod intended for withdrawal of current of a lightning from the interception rod to a grounding conductor.
  • Grounding conductor — the carrying-out part or set of the carrying-out parts connected among themselves which are in electric contact with the earth directly or through the carrying-out environment.
