A bushing attached on the low-voltage side and the high voltage side of an electric pole transformer

摘要

PURPOSE: A bushing installed in high and low voltage sides of a pole transformer is provided to prevent breakage by using a polymer composite material for easy delivery and treatment and for high impact strength. CONSTITUTION: A bushings(1) is installed in a high voltage side of a pole transformer(100), and a bushing is installed in a low voltage side of the pole transformer(100). The bushings(1) are formed of a composite material, and include conductive cores(3) which are screwed with internal clamp terminals(5) in the upper part to introduce voltage into the pole transformer(100). The bushings(1), the cores(3) and the clamp terminals(5) are integrally formed and molded to prevent formation of holes. The conductive cores(3) have the shape of an ellipse or a rectangle. The bushings(1) have high impact strength and light weight to be easily fabricated and delivered.
