JMV offers the exothermic JAMWELD powder to proceed with the exothermic welding procedure that provide the rigid joints. The JAMWELD powder, it is a mixture of copper oxide that generate easy connections in the earthing system. Exothermic welding is a permanent welding solution which can be achieved with the help of this material. At the time of installation, one just need to por it and ignite it. Becuse of the presence of oxygen along with copper it will ignite easily and will come into the molten form and fills up into the cavity of the joint. WIthin 2-3 minutes and exothermic coonection is ready which is one of the best technology when it comes to underground connections.
