The plastic shell of power supply is equivalent to our clothes, which plays an important role in protecting the appearance of power supply. If the power supply is exposed to the air for a long time, and if some dust or other sundries enter the power supply and affect the normal use of some parts and accessories, the service life of the power supply will be greatly reduced, and there will be some hidden dangers. Moreover, for some electricians, there will be some hidden dangers if there is no plastic shell of the power supply during operation, For example, the aging or loose wires inside the power supply lead to leakage, which are important hidden dangers that affect our life safety.

Especially for some businesses, when selling power supply, they will choose some good-looking shells to match, which mainly plays a visual marketing effect. Therefore, there are different types of plastic shells of power supply flowing in the market now.
