34. Copper Clad Steel/ Aluminium 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.

36. What is Exothermic Welding System?
Copper to Bi-Metal and Aluminium
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.

42. Lightning Risk assessment Study is actually the
measure of risk of a lightning strike and probability
of damages. As Per IEC62305-2.
All these calculations are based on:
lightning strike density in that particular area (provided by OMV i.e. Ng = 8),
Danger for people,
Occupation coefficient of structure,
Relative location of site,
Fire Risk,
Associated services,
Electrical Lines,
Lightning Protection Level,
Surge Arrestor and
Dimensions of installation.

43. Lighting Strike Density (Ng)
It is the measure of lightning strikes per kilometre square per year in the
particular area.
Higher the lighting strike density, higher the probability of lightning strike which needs higher level of
lightning protection level.
Danger for People (h)
It is the factor of presence of people and panic in the building in case of a
lightning strike
No particular danger 1
Low panic level(<=2 floors, < 100
persons
2
Medium risk of panic (< 1000 persons) 5
Difficult to evacuate (disabled people,
hospitals)
5
High risk of panic (> 1000 persons) 10
Hazard for surroundings or environment 20
Contamination of surroundings or
environment
50
Occupancy Coefficient (Lf1)
It is the risk reduction factor with respect to theoccupancy of the building / installation. For example, loss due to lighting strike is higher in
hospital as compared to a store / warehouse.
Structure unoccupied 0.1
Structure normally occupied 0.01
Relative Location of Site (Cd)
It is the risk reduction factor with respect to the location and surrounding of the building / installation. For example, chance of lighting strike is
minimized if the building is near to a high tower.
Structure surrounded by higher objects
or trees
0.25
Structure surrounded by similar or
lower objects
0.5
Isolated structure-No other objects
nearby
1
Isolated structure on top of a hill or a
hillock
2
Fire Risk (rf)
It is the risk reduction factor with respect to the flammability of the material present in the building / installation. For example, in case of lighting strike, loss will be very high at a
gas station as compare to the cement store.

High 0.1
Ordinary 0.01

45. PASSIVE PROTECTION SYSTEM

46. The Simple Rod air terminal is composed from a metallic rod with 2 to 8 m height
dominating the structure to protect, and linked to 2 down conductors minimum,
and 2 earthing systems. The protection radius ensured by this air terminal which is
limited to 30 m more or less (Protection level IV, height = 60 m), especially
dedicated to the protection of small structures or areas like towers, chimneys,
tanks, water tower, antenna masts…
The EN 62305-3 standard describes the installation procedure for these air
terminals.
13 Simple Rods, 13 down conductors, and 13 earthing systems are necessary to
ensure the protection below :

47. The meshed cage protection is composed from a meshing in roof surface and in
the front face around the building. Surrounding the roof surface, and on high
points, capture points are positioned. A conductors’ network is placed at the outer
perimeter of the roof. This network is completed by transverse conductors. The
size of the meshing is 5 to meters, and depends on the efficiency needed for the
protection. On the front face of the building, the down conductors are linked at the
top to the meshing of the roof. And, down, to specific earthing systems. The
distance between two conductors is 10 to 25 meters, and depend on the efficiency
needed for the protection. The EN 62305-3 describes the installation procedure for
this method.
Generally, this method is heavy and expensive, due to the complexity of the
structures to protect.
26 capture points, 26 down conductors and a grounded loop earthing system are
necessaries to ensure the protection of the structure here below :

48. The catenary wires protection is a method closed to the meshed cage
principle, because it is constituted with meshing of the conductors far
from the structure to protect, to avoid any contact with lightning
current. Catenary wires are located over the structure to protect,
connected to down conductors and specific earthing systems. The
width of the meshing and distance between the down conductors must
respect the same rules as for the meshed cage. The EN 62305-3
describes the installation procedure for this method.
Generally, this method is heavy and expensive, due to the complexity of the
structures to protect.

49. The ESE air terminal is a terminal which enables to generate artificially an upward leader
earlier than a simple rod, with an ionization system, in order to establish a special impact on
its point. The capture of the lightning strike being faster than a simple rod, this technology
enables to benefit from larger protection areas, ensuring protection for large dimensions
structures.
The generated protection radius depends on the early streamer emission value of the air
terminal (Δt in µs), its height, and the efficiency of the protection. The protection radius
ensured by this type of air terminal is 120 m (Protection level IV, height = 60 m , early streamer
emission time 60µs) The NFC 17-102 standard describes the installation procedure for this
type of air terminal.
The installation of this type of air terminal is easy and cheaper than other technologies. It can
protect whole buildings with one E.S.E. air terminal. It enables the protection of a structure
and its environment, the protection of opened areas and well integrate in the architecture of a
structure without aesthetic alteration.
1 ESE, 2 down conductors and 2 earthing systems are necessary to ensure the protection below :
