Air cored reactors are manufactured by building the winding on a former with suitable insulations and spacers to hold the winding in strength and to restrain the turns from any movement caused by compressive forces. Reactors are made of Aluminium / Copper winding without any core. The reactors can be assembled in vertical as well as horizontal construction.
There may be Dry Type or ONAN Cooled Reactors under Air cored reactors category.
