Leading The Nation Towards Electrical Safety

Chemical Earthing System as Per IEEE 80 and IEC
62561 Standards
The term grounding means connect your equipment or appliance to the ground
by making some arrangement. The grounding can be done by two types: Neutral
Grounding and Body Grounding. Neutral grounding removes the problem of
arcing ground. It is useful in discharging over- voltages to the earth due to
lightning. While body grounding is used for safety of personnel by grounding of
non- current carrying metal parts to earth.

The earthing systems are of two types:
Conventional Earthing- This is a traditional earthing which uses salt, charcoal,
GI/Copper plate, GI/Copper pipe, clamping, brazing, bolting, cemented chambers
etc. The salt and charcoal requires replacement in every 3-4 years. Due to more
moisture, the plate and pipe get corroded after sometimes which results in the
reduction of life. And sometimes it fails to provide safe discharge path for fault
current due to corrosion. The installation requires more area as it needs the
depth of 30-40 feet. The connections made by pressing and tightening contact
connection get loosened after sometime. This causes the current to get hold and
may damage your system. The cemented chambers are highly weighted material
which cannot be removed easily when the earthing requires maintenance.

Leading The Nation Towards Electrical Safety
Chemical Earthing- This is a modern earthing which employs latest technology.
The components that are involved in the installation process are vertical
conductors, connecting conductors, exothermic welding, earth enhancement
compound and pit covers. The vertical conductor requires the depth of 8-10 feet
only. This type of earthing is maintenance free and offers long life up to 20-25
years. A copper bonded rod of 250 micron copper coating over mild steel is used
as vertical conductor which enhances its conductivity and manufacturing strength
since it is physically stronger than copper. Copper clad steel is used for connecting
the equipment to the earth which is flexible in nature, corrosion resistant material
and will not tear or crack if bent. The earth enhancement compound absorbs the
water and provide safe discharge path for fault current which makes it free from
maintenance. We are offering an absolute solution of earthing which offers low
resistivity.

Installation Process
 Make a borehole of 250 mm diameter and 10 ft. deep into the earth.
 Lower the copper bonded rod of dia. 14.2mm, 17.2mm or 23.2mm and 3
meter length into the depth of ground.
 Fill the annular space between the rod and the borehole walls with earth
enhancement compound.
 Cover the top of the borehole with a pit cover.
