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.

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.

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.
Exothermic Weld System
Exothermic Weld Joints Vs Mechanical Joints
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 can be done on Copper, Copper Clad Steel, Galvanised Iron, Stainless Steel, Steel Rail, Bronze, Brass, Monel, Cast Iron, Columbium, Niobium, Wrought Iron

Process of making Exothermic Joints Label
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)
Mould Lid Igniter Starting Powder Weld Powder Graphite Mould Steel Disc Tap Hole
Weld Cavity
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.
