Copper-Bonded Ground Rod

Copper-Bonded Ground Rod Built from high tensile steel, Kumwell copper-bonded ground rods can be hammered to the ground. Also, the ground rods are made of a nickel-plated technology, resulting in high-adhesive-copper bonding, which is not disunited when planted to the ground. The copper has a minimum thickness of 250 microns, a lifespan of around 40 years (pH6-8), and extended capability. The copper thickness can also be increased to 1,000 microns for an even longer lifespan. There are two series of Kumwell copper-boned grounds, which are the UL Series and TIS Series.

 UL Series Passes and UL listed, UL Series ground rods also complied with IEC 62561-2 and TIS 3024-2:2020.

 TIS Series 
TIS Series passes the TIS standard and abides by TIS 3024-2, which complies with IEC 62561-2.

 Solid Copper Ground Rod 
Kumwell solid copper ground rod is built from pure electrolyte copper, which has high resistance in various grounding environments, such as pH>8 or saline area (e.g., seashore). It also passes IEC 62561-2 standard.

*Caution: Do not directly hammer the ground rod into the ground; please dig a borehole before ground rod installation. Otherwise, the ground rod will be chipped and damaged.*

 Stainless Steel Ground Rod 
 Stainless steel ground rod is IEC 62561-2 certificate. It is built from 316L stainless, which has high chemical resistance in all types of grounds, especially pH<6. Additionally, 316L stainless is a low carbon type, and it has a stronger weld than 316 stainless when proceeding exothermic welding.

*Caution: stainless steel ground rod under IEC 62561-2 standard must have molybdenum composition >2% for rust prevention. Consequently, an ordinary 304 stainless cannot be used as a ground rod abided by the IEC standard. *

Bare Copper 

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.

  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-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.

Grounding Components Importance

There are several main objectives for well-designed grounding systems: personal safety, equipment protection, signal reference quality, faults & surges return path, and static dissipation. Also, connections in the ground network are subjected to severe corrosion, high mechanical stress due to electromagnetic force, and thermal heating due to high current magnitude during fault conditions. Grounding components are crucial grounding support to meet the well-designed goals, which are maintaining a low contact resistance under adverse conditions for the expected lifetime of the groundings systems.
