You will find minimum pointers for connections, rod measurement, base thickness, cable configuration. Copper is a far better conductor than aluminum even so the Aluminum components are created greater than the copper product for that reason producing up for aluminum’s lesser conductivity.

Supplies ideal for use in lightning protection units are listed, labeled, and analyzed As outlined by UL Typical ninety six. Thought for conductor style features maximizing area area to hold lightning and suppleness in the configuration to make bends and turns needed in installation methods. Air terminal bases efficiently accomplish the transfer of a strike from termination device to cable conductor and securely mount to numerous constructing surfaces underneath extreme climatic conditions.
To deliver the most effective experiences, we use systems such as cookies to store and/or accessibility gadget info. Consenting to those systems enables us to course of action knowledge including browsing habits or one of a kind IDs on This website.
Bonds join metallic roofing elements and grounded creating devices to the primary conductor, avoiding lightning from leaping in between objects.
A passive grounding system like lightning protection just isn't quickly assessed by laymen – you may’t flip a swap or here turn on a faucet to find out if it is in Functioning situation.
Our enterprise continues to be in business enterprise given that 1966, and household owned. We’re not just below now to provide you a thing but are going to be in this article to suit your needs later on When you've got a concern and wish us.
The strike termination system defends the construction from lightning attachment by offering chosen attachment details. Copper or aluminum air terminals are preferred normally dependent on their own conductivity and suitability to publicity to weather conditions. Capable outstanding metallic setting up elements could also provide the function.
A ground loop encircling a structure interconnecting all downlead cables at their foundation and/or grounding electrode units is The easiest method to equalize prospective for a whole lightning safety method.
The truth is, most buildings need multiple lighting rod, Willard describes. The rods needs to be spaced through the structure’s key ridge, by using a maximum distance of twenty toes among them.
When being forced to use a cable splice often known as an “finish to end” or “straight” or “tee”, or “twin”, There's two types offered.
Given that splitting the lightning together several paths commences in the strike termination stage and follows through the conductor process to floor, different resistance values of electrodes can upset this operate. An in-floor loop solves this prospective challenge and offers an in depth wire community to boost the grounding process.
When it comes to lightning and its stupendous Power, the bottom line, says Willard, is lighting rods, when set up accurately, present a powerful route to floor for electrical Electricity, So mitigating or avoiding harm to properties.
In advance of setting up the lightning rod procedure, it's vital to organize the roof appropriately. Start out by pinpointing The best locale for your lightning rod, ensuring it's the highest stage in the construction.
