KINGSMILL EARTHING PDF

Earth Bars Disconnecting Links Earth bars manufactured from copper with single or twin disconnecting links and multiple earthing points up to 30 way are available from stock — tinned copper versions available for high corrosion atmospheres. Customised bars and earth bosses made from copper or stainless steel can be designed to suit project applications to provide a common earth connection point for buildings and steel structures. Earth bars are made from high conductivity 50 x 6mm hard drawn copper bar with M10 stud fittings for cable lug termination or earth tape connection — suitable for mounting to wall, switchgear or electrical equipment via countersunk wood screws. Selection considerations: Environmental Conditions — earth tape conductor must withstand installation application with respect to corrosion, temperature, UV, aesthetic and structural factors.

Kagalrajas For external bonds the cross section of the bonding material should not be less than that of the main conductors. The most common terminations are copper earth rods driven into the ground.

The earth electrodes being positioned near the equipment where a fault current was expected to pass. Traditional taper-pointed air terminals 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.

The purpose of the down conductor is to provide the low impedance path from the air termination system to the earth system. Kingsmill Earthing have been manufacturing excellence since The most important difference is that the earthing system is designed to ensure that potentials in its vicinity are below appropriate limits.

In the past, it was normal practice to design an earthing system to achieve a certain impedance value. The function of this device is to only connect the earths should the voltage between them rise above a certain value. Elements of a Lightning Protection System. Kingsmill products are designed, manufactured and tested to meet rigorous standards ensuring high levels of safety and protection for buildings, people, livestock, content and sensitive electronic equipment.

Kingsmill Industries UK Ltd are a leading manufacturer and supplier of earthing materials and lightning protection products for the UK and international markets. In the resulting calculation, if the risk is found to be less than 1: History of Kingsmill Earthing. Whether or not a building needs a lightning protection scheme depends on several factors. 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.

Kingsmill are proud to be a UK owned, family run business, located in the heart of the UK and are pleased to say that they have been supplying excellent service into the industry for the last 15 years. Each down conductor should also kingsmi,l provided with a test point as a means of isolating the earth electrode for test purposes. 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 Kingsimll type of construction Height above sea level Proximity of other structures such as tall trees The length of any overhead cables entering the structure.

The purpose of a lightning protection system is to shield a building, its occupants and contents from these adverse effects. Click for more info. Kingsmill thrive on solving customer products problems. There are differences in the design limits applying to consumer installations and to supply industry installations and reference should be made to the correct standard to check the limits which apply in each situation.

However, this needs to be assessed in relation to the consequences of a direct strike. Recently, this has changed towards the approach used in North America. Elements of a Lightning Protection System In general materials used for a lightning conductor are high purity copper or earthung of a similar grade to that used in electrical conductors. This commitment to quality follows throughout all aspects of the company including manufacture, development, customer support and service.

The earth system should be designed as a whole since the complete installation should rise in potential together, to avoid excessive voltage differences. The ring conductor is made from copper tape or cable aluminium is not permitted for use below ground and also helps to provide mingsmill equalisation at ground level, in addition to potential grading.

Any good conductor which forms kingamill of the building structure can be employed as a down conductor with appropriate connection to the air termination and earthing systems.

A number of factors will determine whether or not a person experiencing any of these potentials will be at risk, and the standards attempt to take these into account to ascertain the limits below which the design will be considered acceptable.

If the building is above 20m in height or of an abnormal risk this distance should be reduced to 10m. Go kingsmlil to blog index.

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. 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.

Kingsmill aim to provide the highest standard of Earthing and Lightning Protection Products: Since no part of the roof should be more than 5m from the nearest horizontal conductor, a 10m x 20m lattice is generally used on large buildings. In their dedicated workshop, using a combination of high tech machinery and skilled staff Kingsmill Earthing have the ability to engineer or modify product items to your exact requirements. From a simple modification to a complete new bespoke item.

In the past, it was normal practice to design an earthing system to achieve a certain impedance value. There is typically one down conductor for every 20m or part thereof the building perimeter at roof or ground level. This is to ensure that side flashing does not occur. Since no part of the roof should be more than 5m from the nearest horizontal conductor, a 10m x 20m lattice is generally used on large buildings.
