Copper Bond Earth Rod & ACC

Copper Bond Earth

Copper bond earth rods are the ideal driven earth electrodes, as they offer the installer an economical and efficient earth rod grounding system. Pure electrolyte copper is uniformly molecularly bonded into a high tensile steel core to a minimum thickness of 0.254 mm, as UL467 (1996) States:
“The copper jacket shall not be less than 0.010 inch (0.25mm) thick at any point and shall comply with the adherence requirement and bending requirement thus ensuring excellent corrosion resistance and eliminating electrolytic action.”
Deep driven Petunia copper bond earth rods are an economical method of achieving a low earth resistance.

Non Treaded Rod

These rods have no threads. The rods can be deep driven with power hammer or placed in a hole back filled with “Pet Infill”.

Treaded Rod

Coupling threads are formed by a rolling process to ensure thread strength and to maintain the integrity of the molecularly bonded copper

Coupling

Petunia Couplings have a high copper content to ensure excellent corrosion resistance. They facilitate deep driving and also protect the rod threads while using the driving head. GRUN couplers are used for non-threaded and GRU couplers are used for threaded rods.

Special Spike

These spikes protect the tip of the rods and let installer to push the rods to earth easily when driving.

Driving Head

These reusable high tensile steel driving heads are suitable for driving earth rods by hand or with a power hammer. Special driving head are used for thread or non-thread earth rods, but normal driving heads screws into the coupling to allow deep driving of the earth rods.

Solid Earth Rod

These rods are designed for use where extremely high corrosion resistance and exceptionally long life is required. When the solid rods are required, it is necessary to put them into a bore hole and back fill the hole.
These rods are manufactured from hard drawn copper with purity and mechanical properties to BS 2874, hard drawn grade C101, C102

Stainless Steel Earth Rod & ACC.

اThese rods are designed for use where problems may be caused by galvanic corrosion due to dissimilar metals being buried in close proximity. In this situation a copper rod may react adversely with the buried metal, thus allowing corrosion to take place. The solution is to use stainless steel rods or austenitic stainless steel to BS 970 Grade 316S12.

Earth Plates

These solid earth plates are used as a part of an Earthing system. The material is pure electrolytic copper as BS Standard. They can provide long lasting solution where earth rods are not suitable.
Other dimensions are available too.
