Selection of bushing materials for German standard transformers

Selection of bushing materials for German standard transformers

Insulation material: Insulation paper is generally made of high-purity and high-strength cable paper, which has good insulation and mechanical properties. Aluminum foil, as a material for capacitor screens, requires high purity and uniform thickness to 

ensure stable performance of the capacitor core. The porcelain sleeve is made of high-performance ceramic materials, which have the characteristics of high insulation strength, aging resistance, and pollution resistance.

Conductive materials: Conductive rods, wiring terminals, etc. are usually made of high-purity copper or copper alloys, such as 

brass, bronze, etc., to reduce resistance, minimize energy loss and heat generation, and ensure good conductivity.
