However, even without these technical details and the various variations and modifications based on the following embodiments, the technical solutions claimed in the claims of this application can be achieved.

[0021] The embodiment of the present utility model relates to an insulating protective cover, such as Figure 1 and Figure 2 Shown, including:

[0022] In this embodiment, a wire end protection sleeve 1 is provided at one end of the insulating protective cover; the wire end protection sleeve 1 is mainly used for protecting the wire end;

[0023] The lower part of the wire end protection sleeve 1 is connected to one end of the transformer outlet end protection sleeve 2; an angle is set between the wire end protection sleeve 1 and the transformer outlet end protection sleeve 2. The transformer outlet end protection sleeve 2 is mainly used to protect the transformer outlet end.

[0024] An angle is set between the wire end protective sleeve 1 and the transformer outlet end protective sleeve 2. While ensuring the insulation strength, the technical problems in the prior art that the insulation protection cover requires many accessories for installation, is time-consuming to install and disassemble, occupies a large space, and is costly are solved.
