Flyaford
Engineered for superior mechanical strength, high CTI value, and extreme flame retardancy across global power infrastructure.
Addressing the rigorous thermal, mechanical, and dielectric demands of modern electrical distribution systems through advanced thermoset polymer chemistry.
In modern industrial power grids, low and medium-voltage standoff insulators serve as critical structural linchpins. They are charged with providing unwavering mechanical support to heavy copper or aluminum busbars while simultaneously maintaining absolute electrical isolation under high short-circuit electrodynamic stresses, transient thermal surges, and harsh environmental contamination.
ZHEJIANG FLYAFORD ELECTRON CO., LTD. operates at the convergence of advanced polymer material formulation and automated precision compression molding. Utilizing state-of-the-art formulations including Bulk Molding Compound (BMC), Dough Molding Compound (DMC), Epoxy Molding Compound (EMC), and Phenolic Resin (PF), our industrial power insulators deliver superior tracking index resistance (CTI ≥ 600V), zero-halogen flame retardancy (UL94-V0), and mechanical cantilever strength exceeding conventional porcelain and standard unfilled plastics.
Designed to eliminate internal micro-voids, our composite insulators resist electrical breakdown under extreme surge conditions, boasting dielectric strengths >20 kV/mm and partial discharge levels strictly controlled under 10 pC at rated voltages.
Integrated brass and galvanized steel inserts (M3 to M20) undergo specialized anti-torsion knurling and pull-out stress modeling. Rated to withstand installation torque up to 500 N.m without resin cracking or insert detachment.
Formulated to operate continuously from -40°C to +140°C, withstanding short-time thermal excursions up to 300°C. Fully compliant with UL94-V0 and ISO 4589-2 high oxygen index standards for fire safety.

Yes. We operate an in-house mold design and tooling manufacturing center. We custom manufacture threaded metal inserts made from high-tensile brass, copper, or galvanized steel in thread sizes ranging from M3 to M20 (metric or imperial UNC threads). Custom height, creepage distance, and base footprint designs are fully supported with fast turnaround sample prototyping.
Our microcomputer-controlled torsion testing equipment verifies that our standoff insulators achieve torque resistance ratings between 20 N.m and 500 N.m, depending on insert diameter and insulator height. Thread inserts feature deep knurling profiles that prevent rotational slippage and axial pull-out during heavy busbar installation.
With 35,000 m² of factory area and 60+ automated compression molding presses, Flyaford produces over 200,000 insulator units daily. Our comprehensive digital quality telemetry and automated line parameter control maintain a strict defect rate under 100 PPM (Parts Per Million).
