Electropak Ltd has invaluable experience designing and manufacturing blowout coils for the rail industry. A blowout coil is a safety device used to suppress electric arcs created in the air gap between contacts when switching high currents. Magnetic blowout coils overcome this condition by providing a magnetic field that pushes the arc away from the contact field.

On recent blowout coils manufactured for UK trains, Electropak Ltd developed a machine that pre-heated the copper strip to anneal it as it was wound. The tight coils enable the blowout coils to fit in a small envelope of space and reduce the risk of fire on the trains.
