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