Pure copper ground rod

Resistivity of copper and steel in 20 ℃ respectively is 17.24 x 10-6 (Ω mm) and 138 x 10-6 (Ω mm). If the conductivity of the copper is 100%, the conductivity of the standard 1020 steel is only 10.8%, the conductivity of the galvanized steel is only 8.6%, so the conductivity of the copper is about 10 times of steel. 

 

Pure copper ground rod is the conductivity of zhongke electric to provide you with the best ground rod, can use H90, H70, H68, a variety of specifications H65 and H62 brass to make ground rod body, suitable for the use of lightning protection conductive to demand higher occasion. 

Why did you choose zhongke electric pure copper ground rod 

Low electrical conductivity, high electrical conductivity copper plating steel grounding rods is the same diameter length of 10 times, is the conductivity of the hk regal can provide you with the best ground rod material 

More low appearance bright and clean, no burr senior craftsman using high-tech tools to build perfect tongbang, using advanced manufacturing technology, perfect surface; 

Low convenient installation: the installation is simple and can be manual or mechanical construction, installation cost more economical; 

 

Low service life is long: copper in the soil corrosion rate is about 1/10 ~ 1/50 of steel and galvanized steel is more than three times of corrosion resistance, and electrical performance stability, theoretical service life of more than 60 years. 

Low quality accessories products: using high quality materials to build product accessories, 8 years manufacturing experience to bring you more smooth installation experience.
