The scope of this specification covers the supply, installation and testing and earthing system of the entire installation and for lightning protection. IS Code of practice for the protection of building and allied structures against lightning.

Lightning Protection of Structures

It is used when the installation requires the tape to be secured 75mm away from the face of the building. These clamps are used for straight connection of tapes.

Being joints, it can also used as testing points for the network by disconnecting the joints. These earthing accessories are manufactured using high quality raw material of various diameters. We offering One Hole Cable Clip which is widely appreciated for long durability, dimensional accuracy, strong tensile strength, sturdy construction and outstanding performance.

These Bolted Type parallel connector clamps are used for making connection between two wire conductors. They are manufactured from brass with steel screws. Fasteners in earthing systems come in different sizes and materials. These Petunia four way connectors are suitable for crossing over two cable, making straight through joints in a continuous network. Brass one hole tower clamps are suitable for making of electrical connection between the conductor and steel structure.

High strength copper alloy 'U' bolt clamp designed to provide a high quality, low resistance connection between solid circular or stranded conductor and an earth rod or rebar. The earth bonding points, are used for making electrical connection of the rebar to the earthing or lightning protection system. It is provide convenient earth system connection point in concrete structures. Brass tape connector rod clamps are suitable for for use with end of copper conductor to be connected with earth rod, solid copper or stainless steel earth rods.

Crimping type copper tinned cable lug with a hole are used for make a easy connection to structures. These are used for connecting cable conductors in a test point as part of the lightning protection system. The base has a countersunk hole in the middle for securing the connector to the building surface. Petunia offer these Cable Clips where a long durability, dimensional accuracy, strong tensile strength, sturdy construction and outstanding performance required.

Lightning Conductor height may be increased by means of an elevation mast. We recommend, Lightning Conductor Mast should be galvanized steel, is to be min. Lightning Conductor It must be a fixed mounting surface with conductor fixing internal distance is 1 m. It should be installed in such a way that its path is as direct as possible. It should be as straight as possible along the shortest path without sharp bends or upward sections.

The Chem-Rod grounding rod solves problems found with conventional grounding rods by requiring less real estate and fewer electrodes to meet specified resistance. Each Chem-Rod creates an optimal electrical connection to earth with a large conductive surface for enhanced grounding rod lightning protection. The process forms a solid copper molecular bond that does not loosen or corrode throughout the life of the host structure. Compare to compression connectors, split bolts, crimp connectors, brazing, etc. Grounding Augmentation Fill GAF is a lightning protection product from Lightning Eliminators that is specially formulated to help create a low resistance earth interface, making it easier and less expensive to prevent lightning damage.

strike lightning protection, transient voltage surge suppression, and earthing / grounding solutions. For many years, LPI has been providing specialist lightning​.

Lightning Protection Installation Cost Study

A lightning rod US , AUS or lightning conductor UK is a metal rod mounted on a structure and intended to protect the structure from a lightning strike. If lightning hits the structure, it will preferentially strike the rod and be conducted to ground through a wire, instead of passing through the structure, where it could start a fire or cause electrocution. Lightning rods are also called finials , air terminals, or strike termination devices. In a lightning protection system, a lightning rod is a single component of the system. The lightning rod requires a connection to earth to perform its protective function.

Additional risks include injury and death due to lightning strikes. Fortunately, reliable lightning protection of buildings and structures is available. Data on the cost of installing lightning protection, however, has not been readily available. The purposes of this study, therefore, are 1 to understand the cost of installing lightning protection, and 2 to provide building owners and their architects, engineers, and risk management consultants with cost estimating guidelines for use during the planning and design phases of construction projects. The cost data, summarized below, confirm that lightning protection is economical and can be justified on a cost-to-benefit basis in at-risk buildings. The projects include a single-family residence, a low-rise building typical of educational, commercial, and industrial occupancies, and a five-story building typical of many office buildings, healthcare, and similar occupancies.

As a solution we offer you with risk assessment calculations, which helps you to remove the hazards or reduce the level of risk. Our wide range We help you in conducting the soil resistivity survey to determine the electrical resistance of the ground at a specific location. This is done An effective SPD should have a low let through voltage as this is the amount of voltage the equipment being protected will be subjected to

Чатрукьян знал: это первое, чего в любом случае потребует Стратмор. Выглянув в пустую шифровалку, он принял решение. На загрузку программы и поиск вируса уйдет минут пятнадцать. Скажи, что ничего нет, - прошептал.  - Абсолютно. Скажи папе, что все в порядке. Но нутром он чувствовал, что это далеко не .

Сказал, чтобы вы обязательно нам позвонили. Я прав. Сеньор Ролдан уловил некоторое замешательство на другом конце провода.

Какой номер вы набираете? - Сеньор Ролдан не потерпит сегодня больше никаких трюков. - 34-62-10, - ответили на другом конце провода. Ролдан нахмурился. Голос показался ему отдаленно знакомым.

Нельзя дотянуться до звезд, если чувствуешь себя ущемленной, - сказала как-то ее тетушка.  - И если уж попала туда, куда стремилась, постарайся выглядеть на все сто. Сьюзан сладко потянулась и взялась за .

Выдержав паузу, он как бы нехотя вздохнул: - Хорошо, Грег. Ты выиграл. Чего ты от меня хочешь. Молчание.
