AP1001 series

Since 2002, Yangzhou Daheng Electric Technology Ltd (DHE) has been dedicated to design and manufacture secondary bushings for ANSI transformers, including epoxy, tri-angle, porcelain and other polymer type.

High performance polymer materials

Improved polymer to endure larger temperature rating, UV stability, and service life.

High mechanical strength：

Higher impact resistance in comparison to porcelain. Strict inspection of torque force 100% coverage.

High electrical performance：

Higher dielectric strength and superior electrical performance compared to a porcelain assembly. Removal of air gaps and assembly hardware improves partial discharge performance and reduces potential leak paths.
