Termination with porcelain insulator is mainly comprised of porcelain sheath, stress cone, tail pipe, supporting insulator, lug and other accessories. Porcelain sheath has the structure of high strength electrical porcelain and rain-shed of different sizes. It is with good antipollution flashover performance and the porcelain sheath is filled with polyisobutene. This product has mature operational experience and reliable quality.

Pre-fabricated dry termination is integrally composited of stress cone and silicone rubber insulation material.

Dry GIS termination has composite structure of stress cone and epoxy sheath, making the surface of pre-fabricated stress cone clinged to the inner wall of epoxy sheath through spring assembly to reach reasonable interface pressure.
