Any mortgage or other instrument executed by a gas or electrical utility or electric cooperative transacting business in this State which by its terms creates a lien upon any real property interest then owned or thereafter acquired and which is recorded as a mortgage of real property in any county in which the property is located or is to be located shall have the same force and effect as if the mortgage or other instrument were also recorded or filed in the proper office in the county as a mortgage of personal property. Recordation of the mortgage or other instrument shall cause the lien thereof to attach to all after-acquired property of the mortgagor of the nature therein described immediately upon the acquisition thereof by mortgagor and the lien is superior to all claims of creditors of the mortgagor and purchasers of these real property interests, except prior liens of record, affecting the property. The gas or electrical utility or electric cooperative shall file a notice in every county in which the utility intends to claim the benefit of this provision of law and referencing the book and page number of the mortgage or other instrument which is entitled to the benefit of this provision of law. Thereafter, there shall be no further document necessary to create or give notice of the lien upon the real property interest thereafter acquired by the gas or electrical utility or electric cooperative.
