Abstract :
A unique design of a composite polymer bushing is introduced and evaluated. A comprehensive test program defined the mechanical and electrical performance of a conical silicone polymer composite bushing. This evaluation also included aging and pollution tests to assess the long-term stability of the new design. Results show that the composite bushing offers technical and safety benefits over conventional porcelain bushings
