    Embedded Ceramic Insulation Posts with High Mechanical Strength and Excellent Dielectric Performance for Epoxy-Cast Instrument Transformers

    Embedded Ceramic Insulation Posts | High Strength Support Insulators for Epoxy-Cast Instrument Transformers

    Our embedded ceramic insulation posts are structural insulating components designed to be cast inside epoxy-resin current and voltage transformers. These ceramic posts provide mechanical support for internal winding assemblies while maintaining superior dielectric performance within the cast resin body.

    Unlike pure resin structures, our ceramic-reinforced posts offer higher thermal conductivity, better dimensional stability and enhanced partial discharge performance—a preferred solution for premium-grade instrument transformers used in utility and industrial switchgear.

    Key Features
    • High mechanical strength for winding support
    • Excellent dielectric performance within epoxy matrix
    • Low thermal expansion, matching epoxy resin properties
    • Smooth surface for optimal resin adhesion
    • Custom geometries: cylindrical, stepped, flanged designs
    • Ultra-low partial discharge when embedded in cast resin
    • Suitable for 12kV to 40.5kV instrument transformers
    Applications
    • Epoxy-cast current transformers (CT)
    • Epoxy-cast voltage transformers (VT)
    • Combined transformers (metering units)
    • Indoor MV switchgear instrument transformers
    • Post-type insulation support in resin-insulated assemblies
