Flexible Grounding Electrode-Lightning Protection And Grounding Products
First,the basic overview of lightning protection and grounding products
1,Flexible grounding electrode is Oumaan Technology Group independent research and development,independent production of grounding products,is a solid,liquid coexistence,and has excellent electrical conductivity of the gel-like resistance-reducing materials.Lower resistance efficiency coefficient of 0.16.Flexible grounding electrode HD-R10 microscopic presentation of the honeycomb molecular structure,which is conducive to charge storage,enhance the ability of the grounding network of the dissipation of current.Therefore,it can quickly reduce the impact grounding resistance,fundamentally eliminate lightning overvoltage.After forming the Flexible grounding electrode moisture content of up to 65%,its low resistivity can be maintained for a long time.HD-R10 moulding is insoluble in water,itself does not contain heavy metals,in line with environmental standards.
2,Flexible grounding electrode is a liquid product before moulding,when used in the grounding trench poured,moulding and rock and metal grounding electrode surface in close contact with the two different media organically combined together,greatly increasing the effective contact area between different media,test contact resistance<1Ω.
Second,the advantages of lightning protection and grounding products
1,Strong water retention,conducive to long-term stable operation;
2,High resistance reduction efficiency,strong corrosion resistance,stable performance;
3,Can be closely combined with the metal,can be closely combined with the medium;
4,Stable shape,good conductivity,insoluble in water,will not pollute the surrounding environment;
5,Easy construction,small amount of work,on-site shaping,not subject to terrain restrictions,strong ability to absorb lightning current;
6,Industrial frequency grounding resistance and impact grounding resistance remediation effect is remarkable,reduce the lightning strike tripping rate.
Third,lightning protection and grounding products technical specifications
1,Flexible grounding electrode lower resistance efficiency coefficient of 0.16,much lower than the conventional resistance reduction products of 0.7~0.8,the resistance reduction effect is very significant,has been in the average soil resistivity of up to 18,252Ω-m of the booster station will be reduced to qualified grounding resistance;
2,Tested,HD-R10 own resistivity<0.1Ω-m,moisture content of more than 65%,conducive to long-term stability of the grounding resistance,the theoretical service life of 30 years;
3,Industrial frequency short-circuit test change rate of 2.22%,much lower than the national standard of 20%,for equipment safety is greatly enhanced;
4,Lightning impact characteristic change parameter 0.36%,far lower than the standard 20%,so that the grounding resistance in the high-frequency impact is not a big change;
5,Corrosion test coefficient 0.005mm per year,compared with the national standard provisions of 0.03mm per year,can achieve the extension of galvanised flat steel more than 6 times the service life.
Fourth,the application of lightning protection and grounding products
1,Alpine lightning protection grounding;
2,Rocky terrain grounding;
3,Underwater lightning protection grounding(water power station,alpine hydropower station,fishing and light complementary power station,etc.);
4,Desert lightning protection grounding;
5,Industrial grounding;
6,Laboratory lightning grounding(gravitational wave observatory,national defence field land lightning grounding).
