输出端子/套管

Output terminals and bushings are specialized electrical components designed to safely conduct high-voltage electricity from test equipment to external circuits while providing robust insulation and mechanical support. These components feature conductive cores surrounded by insulating materials that prevent electrical leakage, corona discharge, and flashover, with threaded or bolted connections for secure attachment. They are engineered to withstand extreme electrical stresses, thermal cycling, and environmental conditions typical in high-voltage testing applications.

Output terminals and bushings operate by providing a controlled conductive path for high-voltage electricity through an insulating barrier. The conductive core (typically copper or aluminum alloy) carries the electrical current, while the surrounding insulating material (such as porcelain, epoxy resin, or silicone rubber) creates a high dielectric strength barrier that prevents current leakage to the ground or adjacent components. The geometry is optimized to distribute electrical field gradients evenly, minimizing corona discharge and partial discharge effects that could degrade insulation over time.
