A cover apparatus can cover an electrical insulator and an electrical conductor. The cover apparatus includes one or more leg sections for covering a portion of the electrical conductor. The cover apparatus includes a cover section coupled to the one or more leg sections and covering a portion of the electrical insulator. The cover section includes a body portion and an adjustable portion coupled to the body portion at a coupling location. The adjustable portion can be adjusted such that a dimension of the adjustable portion is adjusted according to a dimension of the electrical insulator. An example method of forming a cover apparatus for covering an electrical insulator and an electrical conductor is also provided.
