10. The French Standard for Early Streamer Emission (ESE) lightning protection systems
NFC 17-102 (September 2011 Version)
Harmonization with EN 62305 Series
EN 62305 series standard is recognized as a reference in the field of
lightning protection of conventional type. This standard explains how to
select, install and verify conventional systems of protection against
lightning.
Since there is no particular reason for the rules systems with passive rods
differ from those governing systems with ESE Lightning Protection systems,
NF C 17102, 2011 version has been created to harmonize the two sets of
constraints.
Including stress tests of the previous editions of the NF C 17102 had to be
more severe than passive to ensure proper functioning of ESE Active
Lightning Rod.
Series EN 62305 does not cover ESE Lightning Rod technology devices,
revision of the NF C 17-102 appeared essential to provide the design
requirements of an ESE lightning rod and those of a lightning protection
system that implementing them.

11. The French Standard for Early Streamer Emission (ESE) lightning protection systems
NFC 17-102 (September 2011 Version)
Harmonization with EN 62305 Series
Continued
An international working group was formed to create an entirely new
standard. It was important to have international commentary to use this
standard as a basis for all countries already using ESE Lightning Rod Systems
or those who wish to use it. These countries have taken or will take
standard NF C 17102 (2011 September version) as a reference to create
their own national standards.
So this new NF C 17102 Edition (Version 2011) is a complete overhaul of the
standard following the publication of the series of European standards EN
62305 and EN 62305-3 particularly giving the requirements for protection of
structures against lightning.

12. The French Standard for Early Streamer Emission (ESE) lightning protection systems
NFC 17-102 (September 2011 Version)
Harmonization with EN 50164 Series
The standard EN 50164 is the standard reference for lightning protection
components for which manufacturers and suppliers must test their lightning
protection components to verify the design and quality. As with the standard EN
62305, there is no particular reason that the rules of passive lightning protection
components differ from those governing by ESE lightning protection systems,
revision of the NF C 17-102 was created to harmonize the two sets of constraints.
Furthermore, as the series EN 50164 does not address ESE lightning protection
components technology, revision of the NF C 17-102 appeared essential to provide
the design requirements and quality for ESE lightning protection components.

Harmonization with EN 62 305-2
 The method of lightning risk analysis of the 62305-2 standard Ed.1 was fully
integrated in Appendix A of the NFC 17-102 standard without any modification. It
will be necessary to update the 17-102 standard to reflect the Edition 2 of the
European standard.

Conclusion
The French Standard NFC 17-102 (September 2011 Version) is a
comprehensive standard that refers to many installation and product
standards in the lightning protection domain.
The NFC 17-102 (September 2011 Version) is an exacting standard to
ensure product quality.

26. Copper Cladded Conductor For Electrical
Installation
The Copper Clad Steel Grounding Conductor is made up of steel with the coating of 99.99% pure copper. These
conductors/ wires
or strands are equipped with the strength of steel with the conductivity and copper with the better corrosion
resistance property. The concentric copper cladding is metallurgic ally bonded to a steel core through a continuous,
solid cladding process using pressure rolling for primary bonding. The copper cladding
thickness remains constant surrounding steel. We use different steel grades for the steel core result in Dead Soft
Annealed, High strength and Extra High Strength Characteristics.
The Copper Clad Steel Wire yields a composite conductivity of 21%, 30% and 40% IACS, and available in Annealed
and Hard drawn. We are delivering products with varied conductivity and tensile strength as per the customer need.
Further, the wire can be processed to be silver plated or tinned copper clad steel wire.

27. Most Efficient JointProcess
It is efficient and superior to all existing surface –to-surface
mechanical retention connectors.

28. What is Exothermic Welding System?
Copper to Bi-Metal and Alumenium
Types of Exothermic Joints:
Possible to join any bi metal except aluminum
Exothermic welding is a process of making maintain free highly molecular bonding process is superior in
performance connection to any known mechanical or compression-type surface-to-surface contact connector.
Exothermic weld connections provide current carrying (fusing) capacity equal to that of the conductor and will
not deteriorate with age.
 It offers Electrical connections between two or more copper to copper and copper to steel conductors.
 Highly portable method as it does not require any external power source or heat source, so it can be done
almost anywhere.
 It provides strong permanent molecular bond among metallic conductors that cannot loosen and further will
not deteriorate with age.
 Connection does not corrode with time and it offers permanent conductivity.

follows:
a) 50% of the lightning current will flow through
the ground
b) 50% of the lightning current will flow over the
connected metal parts out of the building:
• about 10% to the water pipe (metal)
• about 10% to the gas pipe (metal)
• about 10% to the oil pipe (metal tank)
• about 10% to the sewage pipe
• about 10% to the power supplier’s incoming feed
• max. 5% or 5 kA shared across all data lines
