Copper Bonded Grounding And Earthing

BHF Earth Rods are made from high tensile-low carbon steel
compling with requirements of BS 4360 Grade 43 A. Each rod is
molecularly bonded by 99.99% pure, high conductivity copper
bondings, each rod is treated with Benzol-triozole derivatives.
Threads on rods are formed by roll threading process, giving
threads extra strength, eliminating risk of chipping the threads
while driving the rods in the ground.
Solid Copper Earth Rods
BHF Solid copper earth rods are made in two types. Externally
threaded and internally threaded. Solid Copper earth rods are used
where the factor of corrosion is very high and expectionally long life
is required. Hence these rods are manufactured from pure and high
conductivity hard drawn copper to BS 2874-C 101. These rods are
also available with tin plating in order to reduce the risk of oxidation
and increasing shelf life.
