7. Minimum Requirement and Earthing Calculation

9. Surge Protection Devices
Surge is defined as a significant increase in voltage above the designated level in a flow of
electricity, which lasts for 3nano seconds. It is a sudden or quick increase in voltage. According
to IEEE amendments, a transient surge event is an extremely large overvoltage more than 1.8
times the normal voltage which lasts for 3nano seconds.
One Cycle (16667µSec)
Transient S urge E vent
0 90 180 270 360
According to a study the most frequent reason of
damaging an electrical & electronics devices is SURGES.

The sources of surge generation are:
Direct Lightning Distance Lightning On-off Switching
Ground Potential Rise Cloud to Cloud Strikes Signal Surge Generation

Earth Enhancing Compound
We are offering RoHS compliant earth (ground) enhancement compound, which is a highly
conductive material designed to lower grounding system resistance and improve grounding
effectiveness in high resistivity soil conditions. They can be used in sites installed in areas with
poor soil conductivity (such as rocky ground and sandy soil).
Our optimum quality earth enhancing compound complying IEC 62651-7 standard according to
which the compound has passed various tests like Leaching, Sulfur, Resistivity and Corrosion test.
The range of Earth Enhancing Compound is as given below:
 JAM Plus.
 JAM Fill.
 JAM Magic.

Copper Clad Steel Conductor
 Complying IEEE 80, ASTM B 869-96 and ASTM B 452-93 standard.
 The bimetallic component offers a strong conductor, which can
withstand more mechanical abuse than solid copper wire.
 Superior mechanical strength makes Copper Clad Wire less likely
to be damaged during installation or fatigue from vibration or
bending.
 Copper Clad wire and strand has been specially designed with a
low carbon steel core to give the maximum amount of flexibility,
while maintaining high strength.
 Copper cladding is permanently bonded to the central steel core.
 It has very little scrap value, discouraging theft and leaving the
grounding system intact.
 Copper Clad Wire and strand exhibits the same corrosion resistant
properties as copper, but maintains the high strength of steel.
 Excellent Fault Current Carrying Capacity varied as per the
dimensions.

14. Continue…………………
Advantages:
 Best alternative of Solid Copper.
 Physically stronger than Copper.
 Easy to install, hard to damage.
 Theft proof and cost effective.
 Reduces the number of joints.
 Cut it, Lay it and connect it.
 Durable and flexible.
 Less scrap value.
 Harder to cut.

Earthing Accessories
Along with earthing rods and compounds we are also a leading manufacturer and supplier of best
quality Earthing Accessories to provide user friendly earthing installation. Our earthing accessories
consists.
 Earthing Pit Covers.
 Clamps & Couplings.

16. Exothermic Weld System
Exothermic Weld is the globally accepted
method to make permanent, reliable and safe
connections for any electrical installation.
It is a method of making superior quality
electrical connections between two or more
copper to copper and copper to steel
conductors.
Exothermic Weld Joints Vs Mechanical Joints
*Exothermic can be done on Copper, Copper Clad Steel, Galvanised
Iron, Stainless Steel, Steel Rail, Bronze, Brass, Monel, Cast Iron,
Columbium, Niobium, Wrought Iron

Mould Lid
Igniter
Starting Powder
Weld Cavity
Graphite Mould
Weld Powder
Steel Disc
Tap Hole
Step 1
Place the conductor in
the mould after cleaning.
Step 2
Close the mould with the
help of handle clamp.
Step 3
Place the disc into the
mould. Pour the weld
powder into the mould.
Step 4
Close the lid & ignite
using flint igniter.
Step 5
Open the mould after few
minutes once the metal
solidifies. Remove the
slag from the mould
before making the next
connection.
Exothermic Welding System meets or
exceeds:
 UL 467
 IEEE 80, 837 and 1100
 NFC 15-100
 NEC Article 250
 BS 6651
National Electrical Safety Code (NESC)
