When does a power adapter use insulation cover technology?

In general, there are three common insulation cover techniques for power adapters, one is reinforced insulation technique, the second is additional insulation technique, and the third is basic insulation. Under what circumstances will insulation cover technology be used?

For example, in the working process of the power adapter, occasionally there will be circuit inrush suddenly higher than the risk voltage, and then in order to ensure the normal use of the switching power supply, we must use insulation cover technology.

First of all, we first analyze the strengthening of insulation technology, this method is more common, its main role is equivalent to the double insulation effect, in the use of this technology for the power adapter circuit design, in the inside of a single layer of the minimum thickness of greater than or equal to 0.4mm for the best, so that there can be a number of layers of insulation to protect, and this technology is also to avoid electrocution of the many insulation system one.

The second type of insulation cover is the basic insulation. This way is very common, but also to solve the switching power adapter insulation cover the most basic method

Finally, let's talk about the additional insulation technology of power adapter, applying this way, first of all, we have to pay special attention to, the minimum thickness of the additional insulation single layer must be greater than or equal to 0.4mm, so that it will be effective. And the principle of this technology is independently added to the basic insulation, which is the cover of the power supply secondary.
