The basic insulation must be capable of withstanding the possible
stresses during the functioning of the equipment without losing its integrity.
Electric fields, mechanical collisions, high temperatures, and
the aging of the insulating material are the possible causes of failure
of the basic insulation. It is essential, then, that the basic insulation has
sufficient mechanical strength to withstand the stress caused by the
normal operation of equipment. As a consequence, insulating paints,
and similar products, cannot be considered suitable for the basic
insulation; however, they can be used as the functional insulation
(e.g., insulation between windings of transformers or motors).
