Disaster Management and Warning Systems June 2017
Safe Practice in Earthing and Protection
Almost 30000 people die due to Nature Disaster . 20 % of death occur due fires in Forest .
30 % deaths that occur in Earth Quake 30% deaths due to Lightning due to Rail 10% death due to Floods 10% deat due to wind
Disaster MEAN(Emergency)
• Any incident which impact Mass Live comes under disaster reason may be Weather • (Wind,Water,Cloud) and Earth Reaction. • Another may Fire in Jungle. • Prevention • Managing Alert Messasge by Authorties. • Early Warning Ligthning,Earthquakes,Sunami,High Wind Speed • Countinous Collection of data from Warning Devices and Analyse • Awarness and Education Programme

Lightning can occur cloud to cloud, cloud to ground, cloud to air, or within a cloud
Typical Cloud to Cloud Lightning Stroke
(a) Negative charge descends the cloud in a series of steps (roughly 50-100 long)—called a 䇾stepped leader䇿
Typical Cloud to Cloud Lightning Stroke
(b) As the stepped leader approaches the surface, positive charges moves upwards to meet it. When the potential gradient (volts per meter) increases to about one million volts per meter, the insulating properties of the air begins to break down
Typical Cloud to Cloud Lightning Stroke (negative lightning)
(c) With break down, a return stroke begins, with negative charge surging downward in the cloud.

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