Indeed, during the assembly of the transformer, and at the end of the winding drying phase, it is sometimes necessary <\/span><b>to adjust the height of the windings.\u00a0<\/b><\/p>\n<p><span style=\"font-weight: 400;\">When they are empty, the lifting bags are thin and flexible. It is then<\/span><b> very easy to slide them between the windings<\/b><span style=\"font-weight: 400;\">. Once inflated with air, they gently lift the coil without deforming it. The operator can insert or remove the shims to adjust the height of the coil.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This transformer winding adjustment system is <\/span><b>an alternative to the traditional hammer wedge<\/b><span style=\"font-weight: 400;\">.
