Earthing

Hi Friends

My host here at Trivandrum (capital of Kerala State, called Gods own
country, India - yes the place is really glorious) runs a small
factory and wants to produce earthing kits.

He says the galvanized iron pieces that are normally used in this wet
and hot climate get rusted in no time and become poor conductors.
Copper too gets thick greenish coatings with the same effect.

My host is actually doing small things using stainless steel and needs
to know how he can about making stainless steel earthing kits that
will last longer than the steel and copper ones - different types
according to usage.

Google search has thrown dome information on grounding but not much of
help in tnis instance :-(

Does anyone already manufacture stainless steel earthing products
Stateside or Europe?

Any leads, links welcome.

Frankly I myself am not of much help. Though I dabble in electronics
occasionally it is more a hobby. But I am a regular here as well as
SED and I have seen post earlier on earthing and thought I can get
help here.

Many thanks for your time and help.

http://www.google.co.uk/search?num=...nding+rod&meta=

The above link shows plenty of makers of stainless steel grounding
rods.

Below are some more taken from that Google search...

"In a grounding system, the ground electrode provides the physical
connection to the earth and is the instrument used to dissipate
current into it. There are two main types of electrodes.

"Natural" electrodes are intrinsic to the facility and include metal
underground water pipe, the metal frame of the building (if
effectively grounded), and reinforcing bar in concrete foundations.

"Made" electrodes are installed specifically to improve the
performance of the grounding system and include wire meshes, metallic
plates, buried copper conductor and rods or pipe driven into the
ground.

The ground rod is the most widely used grounding electrode. ERICO is
the world's largest manufacturer of ground rods and offers a complete
line of rods and accessories to meet the needs of every user.
Features

# Type 304 solid stainless steel
# Service life up to 40 years
# For use in highly corrosive soils
# Pointed and sectional rods available
# Contact ERICO for other sizes
Applications

The ERITECH range of stainless steel ground rods includes pointed and
sectional rods."

""ACE" stainless steel ground rods are used to overcome many of the
problems caused by galvanic corrosion which can take place between
dissimilar metals buried in close proximity. Other advantages of
stainless steel rod are that they are highly resistant to corrosion
and are much more anodic than copper.

Thanks for the information, Mike, it was quite useful.

Thanks again for your time,
