Exothermic Welding
Exothermic welding fuses conductors into one molecular copper joint with a current capacity at least equal to the conductor — it never loosens or corrodes, which is why IEEE 80 and IS 3043 recommend it for buried grid joints. LPES supplies weld powder cartridges, graphite moulds for cable, rod, strip and steel joints, handle clamps, igniters and starter kits.
