Recently, this has changed towards the approach used in North America. These are sometimes PVC sheathed copper earth tapes for aesthetic purposes only. If the building is above 20m in height or of an abnormal risk this distance should be reduced to 10m.
The most common terminations are copper earth rods driven into the ground. Internal bonds can however be of smaller cross section since they are mainly for equipotential purposes and are unlikely to carry a proportion of the lightning current.
The code of practice for Protection of Structures against lightning details these and are used to estimate risk. The various standards for earthing provide design limits to be met and together with codes of practice explain how the earthing system can be designed to meet these.
The most important difference is that the earthing system is designed to ensure that potentials in its vicinity are below appropriate limits. In general materials used for a lightning conductor are high purity copper or aluminium of a similar grade to that used in electrical conductors. The purpose of the down conductor is to provide kingsnill low impedance path from the earthibg termination system to the earth system.
The principal parts are detailed below. However, where this is not desirable for technical reasons, an earth potential equaliser can be installed between them.
This should be at least 0. This is to ensure that side flashing kingxmill not occur. The earth electrodes being positioned near the equipment where a fault current was expected to pass.
Click for more info. For this reason, the earth termination should be bonded to the kinsgmill of the earth electrodes. The function of this device is to only connect the earths should the voltage between them rise above a certain value.
To do this properly the lightning protection system must capture the lightning, lead it safely down to earth, and disperse the energy within the ground. For external bonds the cross section of the bonding material should not be less than that of the main conductors. There would therefore be a potential difference between them. Whether or not a building needs a lightning protection scheme depends on several factors.
There are differences in the design limits applying to consumer installations and to supply industry installations and earthnig should be made to the correct standard to check the limits which apply earthig each situation.
However, this needs to be assessed in relation to the consequences of a direct strike.
Lightning Protection & Earthing – A Brief Guide By Kingsmill Earthing
The low impedance materials are required to ensure that the lightning energy will flow safely to the ground. History of Kingsmill Earthing. From a simple modification to a complete new bespoke item.
Kingsmill thrive on solving customer products problems. Since their inception inKingsmill have gone from strength to strength and have developed into one of the industry market leaders – Kingsmill have done this by focusing on service, quality, price, delivery, commitment and trust. At all times consideration must be given to the possibility of side flashing. There is typically one down conductor for every 20m or part thereof the building perimeter at roof or ground level. In the past, it was normal practice to design an earthing system to achieve a certain impedance value.

Where practical they should be routed directly from the air termination to the earth system and be spaced symmetrically around the outside walls of the structure. Elements of a Lightning Protection System In general materials used for a lightning conductor are high purity copper or aluminium of a similar grade to that used in electrical kinsgmill. Kingsmill Industries UK Ltd are a leading manufacturer and supplier of earthing materials and lightning protection products for the UK and international markets.
The ring conductor is made from copper tape or cable aluminium is not permitted for use below ground and also helps to provide potential equalisation at ground level, in addition to potential grading. See – Copper Earthing Mats Lattice For Combatting Step Potentials Problems ii Touch Potential the potential kingsmil during fault conditions between exposed metalwork and a point on the soil surface iii Transfer Potential the potential difference between as insulated cable connected to a remote earth reference and the earth rod A number of factors will determine whether or not a person experiencing any of these potentials kintsmill be at risk, and the standards attempt to take these into account to ascertain the limits below which the design will be considered acceptable.

Kingsmill Earthing have been manufacturing excellence since Soil resistivity The external dimensions of the structure including any adjacent structures that are electrically connected The flash density in thunderstorm days per year for the area The type of construction Height above sea level Proximity of other structures such as tall trees The length of any overhead cables entering the structure. Earthing The various standards for earthing provide design limits to be met and together with codes of practice explain how the earthing system can be designed to meet these.

In their dedicated workshop, using kigsmill combination of high tech machinery and skilled staff Kingsmill Earthing have the ability to engineer or modify product items to your exact requirements. Any good conductor which forms part of the building structure can be employed as a down conductor with appropriate connection to the air termination and earthing systems.
Kingsmill are proud to be a UK owned, family run business, located in the heart of lingsmill UK and are pleased to say that they have been supplying excellent service into the industry for the last 15 years.
Down Conductors The purpose of the down conductor is to provide the low impedance path from the air termination system to the earth system. Traditional taper-pointed air kingsmiol are not as frequently used today but when they are they should be positioned near those points where a strike is most likely to hit the building.
If exposed metalwork such as pipes or ducts etc.

This commitment to quality follows throughout all aspects of the company including manufacture, development, customer support and service. An important element in the design of a lightning protection system is the consideration of bonding of exposed metalwork on or near the structure. Kingsmill aim to provide the highest standard of Earthing and Lightning Protection Products:
