Composite insulator (Polymeric insulator)
What is a composite insulator? The composite insulator is also called the polymeric insulator. It is developed after toughened glass insulator and ceramic insulators, whose main insulation structure is consists of a fiberglass core (rod) and silicon housing and sheds. One both sides, 2 metallic fittings are installed on each side with crimping technics. These […]
