Abstract
Embodiments of the invention are directed to a method for manufacturing a composite polymer insulator. The method includes: providing an elongate core having a core axis, the core including a first core main section, a second core main section, and a core midsection axially interposed between the first and second core main sections; and mounting a joint sleeve around the core midsection. The method further includes molding a polymeric first housing onto the core such that: the first housing surrounds the first core main section; and a joint section the first housing overlaps and bonds to the joint sleeve. The method further includes molding a polymeric second housing onto the core such that: the second housing surrounds the second core main section; and a joint section of the second housing overlaps and bonds to the joint sleeve.
