aluminum vs copper lightning protectionrichard allen davis obituary

In fact, its modulus of elasticity is 50% greater than steel. The phase conductors are made of aluminium, while the same-diameter neutral conductor is of copper, enabling it to carry a greater current and thus making the cable better suited to coping with the harmonic pollution problems that are so commonly discussed today. ALUMINUM . Using aluminum foil might be more unsightly, but it would work better than paint. Product Image. Round vs Flat Wire Braid | Allied University Aluminum A 5 / L It should be used . This technique created an aluminum core cable surrounded by a thin layer of copper. The hope here is to dissipate the massive currents from direct or nearby lightning strikes to the earth by conducting the energy to the soil surrounding the ground rod. • During this research I have found that: - Grounding/lightning protection is a relatively complex subject. Cable to steel structure must have 8 in.2 contact with steel. Copper is well known for it's excellent conductivity and has proven itself useful in many electronics production environments. Bonded Parts . 14. The difference is in the reactivity of aluminum vs. copper. Bonding conductors are used for potential equalization between metallic metal bodies and the ligh. test typical values (not for specification use) 3. But a round braid wire normally takes up less space than a flat braid wire would. Set spire base over mounting bracket and attach using fasteners provided. Nominal Diameter (Inches) Weight Per 1000 Ft. (lbs) 24. These include expanded metal foils, interwoven wire, conductive paints and coatings, and plated fiber. Download AutoCAD File. Grounding with Copper:Tinning vs. Non-tinning Two applications typically require bonding to steel: (1) grounding indoor and outdoor structures, reinforcing bars (rebar) in concrete construction, fence and gateposts, steel enclosures, etc. What is Tinned Copper? Copper and copper alloys are widely used because they combine unique properties at an economical price. Bonding to steel is one of the toughest types of grounding connections.

If the connection does not extend on to other types of electrodes that require a larger size conductor, the grounding electrode conductor is not required to be larger than 6 AWG copper . Sounds simple but there's more to it than that. x 16" long. The lightning rod requires a connection to earth to perform its protective function. The LPS (Lightning Protection System) is required to: Intercept the lightning strike (the air termination network) Conduct the lightning strike safely to ground (using down conductors, such as copper earth tapes) Class II conductors interconnect and carry current between strike termination devices and grounding electrodes on structures greater than 75' in height. - The average ham cannot usually implement an ideal ground system. If you have a cell tower close by, shielding only the wall facing the cell tower should be enough to shield you. Metal mesh and expanded foil (copper and aluminum) continue to be the most frequently selected LSP solutions for direct LSP effects because they exhibit the high conductivity and high heat of vaporization necessary to handle massive lightning strike current levels. Exterior copper wiring weathers to a pleasing dark shade." Copper looks better with a darker color and shorter points. If they do not already exist, they must be added at the time of lightning rod installation. Class I conductors interconnect and carry current between strike termination devices and groundin.
