Lightning Conductors
When designing a structural lightning protection system using the Faraday Cage principle, it is possible to use one or more of a variety of available conductor system; namely tape conductor or stranded conductor.
The decision about which type to use is often based more on country-specific historical preferences or aesthetic considerations than the superiority of one type over another. High quality Kumwell conductors, plus appropriate fittings are available for all three systems.
Tape Conductors
Tape conductors are easy to install, with no need to straighten for a neat finish. Available in copper or aluminium, tape conductor can be installed bare or with a choice of PVC covering to enable the tape to blend with modern building fabrics
Circular Conductors
Circular conductors can be used in applications where aesthetic considerations are important. Circular conductor is less conspicuous than the tape conductor system and lends itself much better to being concealed. Available in copper or aluminium, circular conductors can also have PVC covering.
Bare Copper
Made from BS EN 13601 copper, bare copper passes IEC 62561-2 standard. It is suited for grounding systems and lightning protection systems.
Tinned Copper
Made from BS EN 13601 copper and coated with tin (durability enhancing), tinned copper passes IEC 62561-2 standard. It is suited for humid or saline areas, such as seashores.
Bare Aluminium
Made from BS 2898 aluminium, Bare aluminium passes IEC 62561-2 standard. It is suited for installation on metal roof in lightning protection.
Galvanized Steel
Made from galvanized steel with low resistivity, Galvanized Steel passes IEC 62561-2 standard. The electrical resistivity is less than 0.15 µm and tensile strength is less than 490 N/mm².
Stainless Steel
Made from 316L stainless (all-superlative chemical resistance), stainless steel is a low carbon type making it unites stronger when exothermic welding. Also, it passes IEC 62561-2 standard. It is suited for high corrosive soils, especially acid soils (pH < 6).
Copper with PVC
Made from BS EN 13601 with high conductivity copper and green PVC cover with low smoke halogen free (LSHF), Also copper with PVC passes IEC 62561-2 standard. It is suited for down conductor in lightning protection.
Aluminium with PVC
Made from BS 2898 aluminium and Green PVC cover with low smoke halogen free (LSHF), Also aluminium with PVC passes IEC 62561-2 standard. It is suited for down conductor in lightning protection.
Copper with Lead
Made from BS EN 13601 copper with lead, also copper with lead passes IEC 62561-2 standard. It is suited for down conductor in lightning protection.
Tinned Copper with Lead
Made from BS EN 13601 copper with lead, also tinned copper with lead passes IEC 62561-2 standard. It is suited for down conductor in lightning protection.
Copper-Bonded Steel
Made from a bonding between low resistivity steel and electrolytic copper, copper-bonded steel has 254 copper thickness and passes IEC 62561-2 test. It is suited for grounding and lightning protection systems in neutral grounds (pH 6-8).
Annealed Copper-Clad Steel Wire (CCS)
Made from a cladding between steel and copper, CCS is a grounding grid according to IEC 62305-3 and IEEE 80-2013 standards. It also passes ASTM B910-B910M and IEC 62561-2 standard tests. It is suited for grounding systems and solutions for thefts prevention.
