the air between phase conductors or phase
conductors and neutral or ground. Concentrated
radiant energy is released at the point of arcing
an a small amount of time resulting
in Extremely High Temperature.

38. Copper Cladded Conductor For Electrical
The Copper Clad Steel Grounding Conductor is made up of steel with the coating of 99.99% pure copper. These
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.
39. Most Efficient Joint Process/Fail Proof
It is efficient and superior to all existing surface –to-surface
mechanical retention connectors.
40. 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
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.

probability of damages. As Per IEC62305-2.
All these calculations are based on:

50. Lightning Protection As Per NF C 17 102/UNE 211186
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/UNE 211186 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.
51. 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, chi eys, ta ks, water tower, a te a asts… The EN 0 -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 :
