What do you mean by breakdown of insulators?
Breakdown of insulators refers to physical damage to the materials used to insulate electrical wires or other electrical equipment. Rubber or plastic can crumble away, it can be abraded, it can crack. No form of insulation is indestructible although some types of insulation are more durable than others. This is particularly a problem if you have wiring on the floor, and people step on it. Just as the soles of your shoes eventually wear away, so will insulation, if you are walking on it. But even without that kind of stress, rubber does tend to become more brittle with age.ANOTHER ANSWER'Breakdown' describes the failure of insulation that occurs when the voltage applied across that insulation exceeds its dielectric strength. This results in the failure of that insulation, and the passage of current through it.
What are the likely causes of your 1995 Mercedes C220 idling erratically like the ignition switch was momentarily turned off?
One possibility is the underhood wiring insulation breakdown. The factory wiring is junk and needs to be replaces after a few years of service, particularely if the car has been operated in the tropics. You purchase the wiring as an assembly and just replace all. The underhood is the largest and most important assembly to replace, but there ia also an assembly going to the transmission. I had to replace all the wiring after about 7 years and 200 000 km of operation in the Florida heat. Even if this is not the problem you may want to consider this replacement, if you plan to keep the car. A very high number of Mercedes cars from the mid 90s, of all models, have this insulation breakdown problem.
