It is important and vital to keep the resistance to soil as small as possible in areas where humans and animals are present. Attention should be paid to this issue as the ground resistance is as small as possible and the side jumps and hazards that will occur in the Protection facilities from lightning in atmospheric electrical discharges.
Ground installation is as important as the lightning itself. Each lightning rod should have its own ground. The purpose of the ground is to flow lightning current into the soil and distribute it in the soil.
They are 99.9% pure electrolytic copper coated products on a low carbon steel body.
These products are in the form of bars , wire,strip. The steel used has a high tensile strength of 600 N/mm2, which ensures that copper coated steel grounding products have high mechanical strength and are extremely resistant to corrosion. Copper thickness on the steel body is minimum 254 Micron and offers 20 years of service life. MIRAYSAN Elektrik manufactures copper coated rod and other grounding products , according to TS en 62561-2 “lightning protection components” standard.It has been used extensively in Turkey and the world markets in recent years.
Copper bonded earthing rod are made from low carbon steel of grade BS 970 or AIS11018 with a high tensile strength of at least 600 N/mm2 . Low carbon steel core are molecularly tended with 99.9% pure electrolytic copper.
Copper Bonded Earthing Rod is a product that helps in dissipating the fault current to help your assets being damaged from the hazards of fault current. copper bonded earthing rod are manufactured according to the Customers which is internationally accepted.
The copper layer is bonded to steel core through an electrolytic process that ensures a perfect and tough bonding between the steel and the copper the Earthing Rods are fully covered with copper without any cracks, holes, cavities etc. and prevent exposure of the steel core to soil and moisture. Therefore it can resist corrosion better and has capacity of being driven to great depths.
Exothermic Welding is used to Joint Copper to Copper or Copper to Steel where conductivity act a very essential role.
Exothermic weld is a effortless, profitable and durable welding connection that adopt a high-temperature exothermic reaction to invent a molecular bond. It does not need an external heat or power source. Exothermic welding is the universally approved method for manufacturing enduring copper-to-copper and copper-to-steel electrical connections. Its achievement star is admirable to all existing surface-to-surface mechanical connectors.
The Exothermic Weld Process is a simple, self- contained method of forming high quality electrical connections. The compact process requires no external power or heat source, making it completely portable. Connections are made inside a semi-permanent graphite mould using the high temperature reaction of powdered copper oxide and aluminium.
An Exothermic Weld Connections is actually a molecular bond formed between two metals such as
copper/copper, copper/steel and steel/steel.
Copper oxide and aluminium are combined and ignited.
Exothermic Weld is a process that achieves the molecular binding among two or more metallic conductors by a chemical reaction. This molecular binding improves mechanical, electrical and anti-corrosion properties compared with any mechanical connection. Exothermic Weld is the best way to make permanent, reliable and high conductivity connections any installation requiring an earthing system.
Exothermic weld is often used to join copper conductors. The Exothermic Weld process joins two electrical conductors by use of superheated copper alloy. An Exothermic Reaction requires no external heat or current source. The reaction occurs between a copper thermite composition that heats the copper. The chemical reaction is aluminothermic, occurring between aluminum powder and copper oxides. The reaction reaches very high temperatures. Reactant powders and a spark is all that is needed for a high energy reaction.
The Process of Exothermic Weld is a method of making electrical connections of copper to copper or copper to steel in which no outside source of heat or power is required. In this process, a special weld material is placed into a high temperature resistant mold and ignited. The process of igniting the particles creates extremely high heat and molten metal (exothermic reaction) up to 1400 degree celsius, and produces a molten metal slag. This liquid copper metal flows into the weld cavity, filling any available space and completes the weld. The weld is then allowed to cool and solidify before it is removed from the mold. The mold is ready for the next weld after a brief cleaning with a brush. This entire process takes only seconds to complete.
Exothermic Weld Connections produce a permanent connection, superior in performance to any known mechanical or pressure type surface-to-surface contact connector. Because the connection produced is a molecular bond, an exothermic welded connection will not loosen or increase in resistance over the lifetime of the installation.
Grounding enhancement powder is a conductive powder, which can dramatically enhance the performance of earthing/grounding systems for superior electrical protection of assets and can create safe zones in areas where traditional earthing methods are unsuitable or ground conditions are of slate or rock.
Ground Rod Installation Instructions
MOST OF US HAVE OVER THE YEARS SIMPLY POUNDED THE GROUND RODS WE USE DIRECTLY INTO THE GROUND AND THEN MADE OUR CONNECTIONS. I HAVE LEARNED THAT THIS IS NOT THE BEST WAY TO INSTALL A GOOD GROUND ROD. IN FACT, POUNDING THE GROUND ROD ALL THE WAY IN DAMAGES THE GROUND ROD AND WILL REDUCE THE LIFE OF THE ROD. WHEN YOU POUND IN THE ROD, THE ROCKS IN THE GROUND SCRATCH OFF THE COPPER PLATING EXPOSING THE UNDERLYING STEEL. THE STEEL CORRODES AND THUS YOUR ROD STARTS TO DETERIORATE. LOCATION CONSIDERATIONS: CHOOSE A LOCATION AS CLOSE TO THE CONTROLLER AS POSSIBLE. ALSO LOOK FOR ROUTES FOR YOUR GROUND WIRE WHICH WILL BE AS STRAIGHT AS POSSIBLE. KEEP IN MIND THAT ELECTRICITY, LIKE WATER, WILL TRAVEL THROUGH THE PATH OF LEAST RESISTANCE. BENDS, CURVES, AND DISTANCE CHANGE CONDUCTIVE CHARACTORISTICS. IF USING A MULTIPLE ROD CONFIGURATION, AND IF YOU HAVE THE REAL ESTATE TO ACCOMODATE, INSTALL THE RODS 2 TIMES THEIR LENTH FROM EACH OTHER. THE GEOMETRIC SHAPE IS NOT AS IMPORTANT AS THE SPACE BETWEEN THE RODS. IF THE ROD IS 10 FEET LONG, SPACE THE RODS 20 FEET APART EITHER IN A STRAIGHT LINE OR IN A TRIANGLE. STEP 1. WITH POST HOLE DIGGERS OR IF YOU’RE FORTUNATE ENOUGH TO HAVE A POWERED POST HOLE DRILL, DIG A HOLE AS DEEP AS YOU CAN OR AS LONG AS THE GROUND ROD. THE ROD NEED ONLY STICK OUT OF THE GROUND ENOUGH TO MAKE A WIRE CONNECTION. IF YOUR ROD IS LONGER THAN YOUR HOLE IS DEEP, POUND THE ROD IN TO ACCOMMODATE THE SIZE DIFFERENCES. STEP 2. BACK FILL THE HOLE WITH A) BENTONITE IF THE ROD IS INSTALLED IN AN ENVIRONMENT WHICH WILL NOT FREEZE, OR B) AN 80/20 MIXTURE OF CONCRETE AND CHARCOAL OF WHICH THE CHARCOAL IS PULVERIZED TO A POWDER. IF YOU PREFERE A PREMIXED COMPOUND, CONTACT US TO ORDER IT. NOTE: FOR THOSE APPLICATIONS WHERE A GROUND PLATE IS USED OR THE GROUND IS SUCH THAT YOU CAN NOT DIG A HOLE; DIG A TRENCH OR EXCAVATE FOR THE PLATE. SURROUND AND COVER THE GROUNDING DEVISE BEFORE COVERING WITH SOIL. ALSO DIRECT BURING BARE COPPER WIRE 2 FEET UNDER GROUND IS VIABLE. THE GOAL IS TO GET AS MUCH GROUNDING DEVISE SURFACE AREA IN CONTACT WITH THE SURROUNDING SOIL. STEP 3. THIS STEP WILL GREATLY INCREASE THE PERFORMANCE OF YOUR GROUND ROD. FROM THE NEAREST VALVE, RUN A DRIP EMITTER LINE TO THE BASE OF THE GROUND ROD SO THAT THE SOIL SURROUNDING THE GROUND STAYS MOIST. IF SO DESIRED, YOU COULD DEDICATE A DRIP ZONE FOR THE GROUND ROD. STEP 4. MAKE YOUR WIRE CONNECTIONS USING 6 TO NO LESS THAN 10 GAGE SOLID COPPER WIRE. MAKE THE WIRE RUN AS STRAIGHT AS POSSIBLE. IF YOU NEED TO MAKE TURNS, USE WIDE SWEEPING BENDS. DO NOT PUT SHARP BENDS IN THE WIRE. USE A GOOD QUALITY COPPER CLAMP TO ATTACH THE WIRE TO THE ROD USING AT THE MINIMUM A STURDY GROUND CLAMP. THE PREFERED METHOUD WOULD BE TO WELD THE WIRE TO THE ROD UTILIZING A FLASH TYPE WELDING KIT. DO NOT JUST WRAP THE WIRE AROUND THE ROD! STEP 5. USE A MEGER, MEGOMETER, OR GROUND RESISTANCE METER TO DETERMINE THE RESISTANCE OF THE GROUND SYSTEM. (IF YOU DO NOT HAVE SUCH A METER YOU CAN PURCHASE ONE FROM CONTROL TECH) YOU SHOULD SHOOT FOR A READING OF 5 OHMS OR LESS, ESPECIALLY IF YOU ARE PROTECTING A VERY EXPENSIVE PIECE OF EQUIPMENT. IT MAY BE YOU’LL HAVE TO USE A MULTIPLE ROD DESIGN TO GET THE DESIRED OHM READING.
With the increasing of demand security system lightning protection, a lot of lightning protection manufacturers to develop security market, but these companies don't quite understand security industry.Under the condition of the market demand increase, of course, many security engineering contractor will also be lightning protection products in addition to the monitoring system, which creates a lightning protection the myth that lead thunder carelessly.And that's what the author at the beginning of the article of interlaced as the hills.Currently exist in the concept of "lightning" two kinds of typical myth: 1 security monitoring support to install the lightning rod.Believe that a lot of people believe that install the lightning rod in the monitoring support to ray causing underground is the safest method, wrong!Isolated poling outdoor camera to prevent direct lightning shall set up independent lightning rod, poling and independent lightning rod distance should be greater than 4.5 meters, the use of wood or cement poling is more advantageous to the insulation insulation materials, camera is best engineering plastic holder, in order to improve the insulation level.2 multipoint earthing invasion of security system provides the path to ground potential, system damage.Multipoint grounding is suitable for high voltage and in monitoring light-current system, single point grounding protection products.Man-made security system of multipoint earthing, introduce the grid "potential" through the loop security system, causing voltage "surge".Weak current system pressure is low, the pressure difference is too big, the damage once the system bear or would be devastating. Through the above analysis, we can understand that, after the correct understanding of lightning protection way, the method in the installation of lightning protection equipment can real protection.To the development of security market of lightning protection I have another concern, given the strong lightning weather occurrence probability and the probability of being struck by lightning, a set of outdoor surveillance system lightning protection equipment is necessary to install?Late prophase construction costs, maintenance and so on, these costs add up and over budget?Security product homogeneity product prices drop, if the replacement of a lightning strike equipment cost is less than the cost of the installation of lightning protection equipment, so the future of the security market of lightning protection in where?Market development breakthrough in where?Official department and how to put forward the standard, how to make a decision this is we should continue to focus on.
A lightning rod is a device which is used to divert electricity from lightning into the ground, where it can dissipate harmlessly, rather than damaging structures and trees or injuring animals which happen to be walking around above the ground. You may also hear a lightning rod called a lightning conductor or a Franklin rod, after the famous inventor Benjamin Franklin. Lightning rods are widely used all over the world in lightning protection systems, and they appear to be highly effective, since lightning-related fires and structural damage have been greatly reduced. Incidentally, English includes the slang term “lightning rod” for someone who seems to attract controversy.
Classically, a lightning rod is made from metal, ideally a very conductive metal such as copper. When lightning strikes, it is drawn to the rod, and it follows a grounding cable into the ground. Lightning rods are supposed to attract lightning, drawing it away from vulnerable structures, and they are also mounted on the roofs of some buildings so that if lightning does strike, it will be pulled to the lighting rod rather than the conductive materials in the structure.
Structures in areas with lots of lightning are often fitted with lightning rods. Many structures also have lightning arrestors, grounded cables near their utility boxes which are designed to divert excess current into the ground, rather than allowing it to blow through the phone and electrical lines, potentially causing a power outage or fire. Some people also use surge protectors at their power outlets which automatically turn off if the current spikes, ensuring that if a lightning arrestor fails, their electronic equipment will not be damaged.
Credit for the invention of the lightning rod is generally given to Benjamin Franklin. Franklin did a number of experiments with lightning, including the famous kite and key experiment, and he was very interested in exploring lightning and electricity. Realizing that lightning was a major threat in some communities, he came up with the bright idea of the Franklin rod, and it quickly grew to be a big hit. Hundreds of years later, people still use his basic design, and lightning rods are even required by building codes in some regions.
There is some debate about the end of a lightning rod. The original Franklin rod was designed like a giant needle, coming to a point at the top. Many Americans prefer this design, believing that the point is highly effective. Some British designers, however, think that lightning rods should be topped with balls, and other designers have come up with variations in which the rod is topped with an array or rack of metal, theoretically increasing the ability to attract lightning. All of these systems seem to work, with design being a matter of personal preference and regional tradition.
